BEST Seiko Dive Watches

As a watch enthusiast and commentator, I try my hardest to approach my articles unbiasedly. With that said, I must admit that an unbiased approach will be difficult with this article, though I will try my best. I am commonly referred to as a Seiko fanboy or someone who is so in love with the Seiko brand that they rarely make mistakes in my eyes. 

Now, I am not entirely blind to Seiko’s rampant QC issues, continuous price creep, and the insane number of limited editions. But even with some of the problems Seiko is notoriously known for, they will always hold a special spot in my heart as a watch enthusiast.

You see, when I first started out my watch-collecting journey, there were a plethora of options when it came to purchasing my very first automatic timepiece. But being young and eager with a very limited budget, I knew there was only one watch that was going to do everything I needed and make me smile every time I looked at my wrist.

Enter the Seiko SKX007, the watch that started it all. A timepiece that is affordable, omnipresent, stylish, and a timepiece that still influences me to this day. So, strap on your floaties and cue up The Abyss, Apocalypse Now, Commando, or Predator because we are talking about the 20 Best Seiko Dive Watches.


I think it is safe to say that for many of us in the watch enthusiast community, me included, Seiko represents a fantastic entry point into the world of automatic watches. They are ubiquitous and affordable and offer the consumer a durable and reliable timepiece that will be the perfect companion for everything short of a black-tie event.

But how, why, and when did Seiko create their first dive watch, leading to the fervent following that they have today?


In order to answer the burning question above, we need to take a trip back in time to the 1960s, a time of political and social unrest, countercultures, and an era where recreational diving was starting to pique the public’s interest and enter its heyday.

Seiko introduced its first dive watch, the 62MAS, in 1965. We will be discussing the 62MAS or rather modern variations at length later in the article. The 62MAS was a watch that personified the skin diver and was fundamental in creating the skin diver silhouette we know and love today.

After the launch of the 62MAS, Seiko opted to take a dual-avenue approach to their burgeoning dive watch program. Seiko would create a professional and more accessible recreational line of dive watches aimed to give both professional and recreational divers timepieces that would meet the needs of the tasks at hand.

For the remainder of the 1960s, Seiko would continue to produce classic and iconic dive watches, giving the world their first 300m dive watch in the 6215-010 and their first hi-beat movement in the 6159-7001. The 70s and 80s were a dark time for the Swiss watch industry due to another development from Seiko; the quartz movement. 

With that said, Seiko continued to innovate throughout the decades, giving us more memorable dive watches for recreational and professional divers, including the saturation-ready Seiko Tuna, some alternatively powered movements like solar and kinetic, and a tiny icon called the SKX.

So, as you can see, in their nearly 60-year dive watch history, Seiko has produced some true icons that have stood the test of time and laid the groundwork for the modern Seiko divers on today’s list.


To begin, we need to have a good understanding of who Seiko dive watches are made for and what purpose they serve. As we discussed earlier, Seiko does a great job of producing watches for the average consumer who might use their dive watch in the pool, at the beach, or for some recreational dives while on vacation. 

But, they also produce very capable dive watches that can be used on a professional level as well. While the latter is becoming less common due to dive computers, there are still Seiko dive watches capable of extreme depths.

Before we get into our list of the best Seiko dive watches, I think it is important to discuss some attributes that make Seiko worthy of your hard-earned money. Below are some characteristics to look for in a Seiko dive watch to make sure it fits your needs.


I think one of the most important things to look for in your Seiko Diver is the water resistance rating. This is the time in your search and evaluation process when you need to be honest with yourself and ask yourself what the watch will be used for. For most, a dive watch will never actually see a dive unless you are diving between the couch cushions to find the remote, in which case a 200m or 300m dive watch is more than enough. 

But for those who like to adventure on the weekends, Seiko, as mentioned earlier, makes highly capable timepieces that will take you to the depths of the ocean, where the only thing you should really worry about is the nightmare fuel that surrounds you.


While I briefly mentioned it earlier, Seiko has been known to have some QC issues from time to time. More often than not, it is alignment issues with the chapter ring or other smaller things. It goes without saying it is something to keep an eye out for when purchasing a Seiko dive watch.

While many of the QC issues are generally found on the entry and mid-level Seiko timepieces, it can still be found on watches nearing the $1,000 mark. QC issues aside, Seiko generally has a solid build quality that will take most things you throw at it.


Last but certainly not least, it is crucial to understand where Seiko lands on the price scale. The prices for many of the entry and mid-level Seiko dive watches have been slowly creeping up over the last few years.

But, it is worth mentioning that many of the timepieces on today’s list can be had for well under $1,000, some for less than $500, but it is worth noting that Seiko runs the gamut when it comes to price as we will see as we get to our list.

The Best Seiko Dive Watches

Alright, now that we have had a chance to learn a little bit about the history of Seiko dive watches and what characteristics to look for in one, let’s get into our list of watches.

1.  Seiko SKX007

As mentioned in the introduction to today’s article, the Seiko SKX007 was my gateway to the wonderful world of watches. While the Rolex Submariner is the quintessential and most iconic dive watch for the luxury market, the SKX007 is the most iconic dive watch for the affordable market.

The Seiko SKX007 has a case width of 42.5mm, a lug-to-lug distance of 46mm, and a case thickness of 13.25mm, meaning it is a great size for an array of wrist sizes. For anyone hesitant, I urge you to give it a chance. The short lug-to-lug makes this watch wear closer to a 38-40mm case watch.

The SKX007 is powered by the Seiko 7S26 movement and has unfortunately been discontinued, which makes pricing the SKX a bit difficult. However, due to such high production numbers, well into the millions, you can still find excellent pre-owned examples for under $200.

2. Seiko Prospex “Turtle” SRPE95

The Seiko “Turtle” is the first watch on our list that has been given a nickname by the enthusiast community. While it might be obvious, the Turtle was affectionately named after a sea turtle due to the case shape, which resembles a turtle’s shell.

With a case diameter of 45mm, the Turtle could scare off many a watch wearer, but it is worth noting that the lug-to-lug distance of the Turtle is only 48mm, and with a case thickness of 13.4mm, this classic Seiko design wears very well on smaller wrists.

Like the SKX007, the Turtle comes equipped with a Seiko proprietary Hardlex crystal. While it isn’t as scratch-resistant as a sapphire crystal, Hardlex, for the price point, is a great option. With an MSRP of $380, the Turtle can be found pre-owned for under $300.

3.  Seiko Prospex “Samurai” SRPF03

Of the watches on our list so far, the Seiko Samurai is the first to have a truly modern design language. Released in 2004, the first generation of Samurai was well received by consumers and has continued to evolve to this day.

The angular case was a design choice that helped appeal to a modern consumer looking for a great dive watch that didn’t rely on a design language from previous Seiko models.

With a case diameter of 43.8mm, a lug-to-lug distance of 45mm, and a case thickness of 13.4mm, the Samurai wears smaller than the Turtle but certainly has great wrist presence due to its modern and angular case.

We will be discussing the evolution of the Samurai with another entry on our list, but this black-dialed variant has an MSRP of $525 and can be regularly found pre-owned for under $400.

4.  Seiko Prospex “Sumo” SPB101

The Seiko “Sumo” is another Seiko dive watch that has become immensely popular due to its availability, robustness, design language, and price point.

Like many watches on today’s list, the Sumo is just one of the many Seiko references that Seiko enthusiasts love utilizing the Seiko 6R35 movement, which has a power reserve of 70 hours. The 6R35 is a rock-solid movement that offers a robust movement with a solid power reserve, making it a great option as a daily driver.

The Sumo has a case diameter of 45mm, a lug-to-lug distance of 52.6mm, and a case thickness of 12.9mm, which means that the Sumo is the largest watch on our list so far but also the thinnest.

The Sumo, much like the Turtle, has the crown positioned at 4:00, allowing for a better wearing experience for those with smaller wrists. You can find the Sumo SPB101 for $850.

5. Seiko Prospex “Shogun” White Dial SPB191

The number five spot on our list goes to the first titanium watch, the Seiko Shogun. While every entry thus far has been cased in Stainless Steel, the Shogun is a wonderful example of a robust dive watch without the weight of steel, meaning it can be worn comfortably on smaller wrists.

The titanium construction has the added benefit of being an allergy-safe metal and stronger than steel, with the only drawback being that it scratches more easily than steel.

The Sumo has a case diameter of 43.5mm, a lug-to-lug distance of 51mm, and a case thickness of 13.3mm, meaning much like the Sumo, it has a longer lug-to-lug and would wear best on a bigger wrist but due to its titanium construction should accommodate smaller wrists as well.

The Shogun comes on a black silicone strap, is the first watch on our list to have a magnifier for the date complication, and has an MSRP of $1,350 but can be found pre-owned for under $1,000.

6. Seiko Prospex “Monster” Save the Ocean Special Edition SRPG57

The Seiko “Monster”, as it has been dubbed, might imply a watch that is absolutely massive, but surprisingly enough, its dimensions are rather tame.

With a case diameter of 42.4mm, a lug-to-lug distance of 49.4mm, and a case thickness of 13.4mm, the Monster is a well-proportioned dive watch that might just be one of the more divisive watches on our list.

I think the Monster design as a whole is a bit divisive; people either love it, or it’s just not for them. But being that this version of the Monster is a Save the Ocean Special Edition, you can bet on it not being your average Monster.

The standout feature of the SRPG57 is the gradient dial of whites and blues meant to represent the colors of the Antarctic waters and the penguin feet pattern, which give the Monster a beautifully textured dial. The Monster has an MSRP of $525 but can be found brand new for under $400.

7. Seiko Prospex “King Turtle” SRPE05

I know what you’re thinking. Haven’t we already read about the Seiko Turtle? Well, the answer is yes, but also no. The Seiko “King Turtle” is the Turtle that Seiko enthusiasts have been asking for, for years. While the Turtle had a massive following, worn by countless watch enthusiasts, there were some drawbacks and a few improvements they wanted to see.

First, the proprietary Hardlex Crystal. While it works just fine, it is still a mineral-based crystal, meaning it is less scratch-resistant than sapphire. So, after listening to the consumer, Seiko replaced the Hardlex with sapphire, and all were happy.

Second, the aluminum bezel insert of the original Turtle was a fine and efficient material, but much like the Hardlex, it was prone to scratches. For some, that is a huge bummer; for me, the scratches and patina give the watch more character.

But to meet the wants of the consumer, they replaced the aluminum bezel insert with a virtually scratch-proof ceramic insert. I think one of the standout features of the King Turtle is the OD Green waffle dial, which resembles the frag pattern of a grenade.

The King Turtle has an MSRP of $595 pre-owned for under $400.

8. Seiko Prospex “King Samurai” SRPE35

Much like the King Turtle, the Seiko King Samurai is the evolution of a tried-and-true Seiko design that was embraced by the masses.

While the watch’s dimensions have remained the same, the devil is in the details. Much like the King Turtle, the King Samurai received the same upgraded specs with a sapphire crystal, ceramic bezel insert, and a waffle-patterned dial.

While I’ll admit the Samurai and Turtle upgrades were just what the watches needed, I wish they would have also upgraded the movements. While both the 4R35 and 4R36 are solid movements, it would have been nice to see an upgrade to a movement that has a better power reserve.

But still, for an MSRP of $625 and commonly being found pre-owned for well-under retail, the King Samurai is a great option for someone looking for an upgraded version of a beautifully designed modern diver watch.

9. Seiko “Darth Tuna” S23631

The Seiko “Darth Tuna” is the first watch on our list to feature a quartz movement (GASP!). But in typical Seiko fashion, the accurate and robust quartz movement is the perfect choice for a professional dive watch like the Darth Tuna.

While we can argue the pros and cons between automatic and quartz movements, it is safe to say that it is a universally accepted fact that quartz movements will always be more accurate and reliable, which is the reason you would use it in a professional tool.

But the dimension that makes this dive watch capable of the 1,000m depth rating is the case thickness, which comes in at a stout 16.3mm.

It is also worth noting that due to a case construction of ceramics, titanium, and steel, you have a dive watch that is lighter than it may look.

Being that this is a professional tool, the Darth Tuna comes with a professional price with an MSRP of $2,400.

10. Seiko Prospex 1968 Diver’s Modern Re-Interpretation GMT SPB381

Seiko Prospex 1968 Diver's Modern Re-Interpretation GMT SPB381

Aside from the wildly pleasant dial of the Save the Ocean Monster, the Seiko SPB381 has one of the most pleasing dials on our list, and it’s a GMT to boot.

The newest “Modern Re-Interpretation” of the famed 1968 Diver is an outstanding timepiece that offers you the ability to track a second timezone with a GMT hand that can be adjusted independently, which is commonly known as a “Caller GMT” as opposed to a “Traveler GMT” which has a jumping hour hand to adjust for local time when you arrive at your destination.

With a modestly sized case diameter of 42mm, a lug-to-lug distance of 48.6mm, and a case thickness of just 12.9mm, this vibrant green GMT is a great size for any world traveler. There is something romantic about a dive watch GMT. It is a watch that is just screaming to go on adventures, and I think that the SPB381 could be you go anywhere do anything (GADA) watch.

With similar specs as the “King Seiko’s” above, the sapphire crystal and ceramic bezel insert mean that this GMT is ready for you to hop on a plane and then off a boat without worrying about some bumps and bruises.

The SPB381 has an MSRP of $1,500.

11. Seiko Prospex SPB143

Now, of the watches on our list so far, I have owned an SKX007, Turtle, Samurai, and Monster, but one Seiko that has been calling to me since its release in 2020 is the SPB143. I have always been a massive fan of the 62MAS and its skin diver design, but my issue with a lot of skin divers is the size.

They have always been a bit small for my 7.3-inch wrist. So, when I saw Seiko released a modern interpretation of the 62MAS with a 40.5mm case, a lug-to-lug distance of 47.6mm, and a case thickness of 13.2mm, I knew I had to one day get my hands on one.

But to this day, it has still evaded my collection. It isn’t because it is hard to find; quite the contrary. It is readily available, which means for anyone looking to find a great dive watch with a vintage flare, the SPB143 is the watch for you.

The 62MAS-inspired dive watch has a domed sapphire crystal and a beautifully designed sunburst gray dial that catches the light wonderfully. And, with an MSRP of $1,200 and commonly found pre-owned for under $800, the SPB143 is a great piece for a fan of vintage with the benefit of modern materials.

12. Seiko Prospex Marinemaster 300 SLA023

The Seiko Marinemaster 300 is a legendary watch from Seiko that has had more variants than I can count, but the SLA023 is among my favorites. I’ll be honest: I’ve never been drawn to blue watches, green, absolutely, but blue has never been a color I’ve owned.

That said, the SLA023 is a blue timepiece I would own in a heartbeat. There is something about the perfect shade of blue, devoid of any green tones, that keeps it from looking teal in certain lighting conditions, which really appeals to me.

Another huge characteristic of the SLA023 that I am a huge fan of is the Monobloc case. The one-piece case design aids in water resistance by eliminating the need for a case back gasket, removing a possible point of entry for water.

The classic and iconic MM300 SLA023 is timeless and is an incredibly robust dive watch with an MSRP of $3,100, but it can be found pre-owned for under $2,500.

13. Seiko Prospex SPB317

Seiko Prospex SPB317

Remember Shrinky Dinks? Those fun art projects you used to do as a kid, well, the SPB317 is kind of like the Shrinky Dink version of the venerable Seiko Turtle with a few minor changes, the biggest being the case size (obviously).

With a case diameter of 41mm, a lug-to-lug distance of 46.9mm, and a case thickness of 12.3mm, the SPB317 is an amazing dive watch for enthusiasts who love the design of the Turtle but don’t necessarily have the wrists to wear one making it, ostensibly, the smallest wearing diver on our list so far.

Some other upgrades worth mentioning are the sapphire crystal as well as the improved movement. The SPB317 utilizes the 6R35 with 70 hours of power reserve.

While you might think it is just a smaller version of the OG Turtle, the SPB317 is most definitely the sum of its parts. With an MSRP of $900, the SPB317 is an option and one that competes with other divers of its size.

14. Seiko Prospex LX SNR029

Seiko Prospex LX SNR029

The LX SNR029 is the second watch on our list to have a case constructed entirely of titanium. But before we move on, I want to discuss the elephant in the room, and I’m not talking about the dimensions of the LX SNR029.

While it is a larger piece, with a case diameter of 44.8mm, a lug-to-lug distance of 50.9mm, and a case thickness of 15.7mm, the elephant I’m referring to is the price tag. 

With an MSRP of an eye-watering $6,000, the LX SNR029 is priced like a timepiece that should have a “Grand” in front of the Seiko name due to its high-quality finishing and the utilization of the 5R65 Spring Drive movement, both qualities usually reserved for Grand Seiko timepieces.

I’ll be the first to admit that, for this amount of money, I probably wouldn’t be putting it into a Seiko, but with that said, this is the absolute top-of-the-line watch for Seiko and does a great job of being the perfect balance between rugged and beautiful.

15. Seiko Prospex Dive GMT SFK001

The next watch on our list is the SFK001, which is the second GMT on our list, and I think the better of the two options for those who do a lot of adventurous traveling.

While there is no denying that the SPB381 is an amazingly design and finished dive watch, it is still a “caller” GMT, which, for those doing business with folks around the world, makes for the perfect companion. It makes much more sense for those who bounce around from timezone to timezone to have a “flyer” GMT.

Enter the SFK001 or the Sumo GMT. The Sumo GMT is not just a flyer GMT but the first GMT of its kind with the brand new Solar Powered 5K65 GMT movement. The 5K65 is definitely the star of the show, boasting a nine-month power reserve, which, if it ever runs down, only takes 15 hours in sunlight to get back to full capacity.

The Sumo GMT has an MSRP of $775 and is my pick for the world traveler looking for an ultra-reliable diver GMT.

16. Seiko Prospex “Arnie” SNJ025

Picture this: it’s the mid-90s, and you are casually watching two of the greatest action films of all time with your buddies. On the screen is the biggest movie star you know, Arnold Schwarzenegger, and on his wrist, one of the coolest watches you’d seen up to that point in your life, the Seiko H558-5000, which would come to be known as the “Arnie.”

That is a 100% true story. As a kid, I loved two things more than anything: badass action movies with buff dudes and a gratuitous kill count and my Timex Indiglo. But it wasn’t until I watched Commando (1985) and Predator (1987) that I realized there was a whole world of watches way cooler than what I was wearing, and I knew one day I had to have that watch.

Luckily for me, Seiko decided to re-issue the H558-5000 in the SNJ025, a Solar Powered Hybrid diver that has a case diameter of 47.8mm, a lug-to-lug distance of 50.5mm, and a case thickness of 13.8mm.

The SNJ025 comes equipped with a multitude of functionality, including a chronograph, daily alarm function, full calendar until December 31, 2100, and an LED light. The construction of the Arnie is a steel case with a plastic shroud.

The Arnie has an MSRP of $525, and for those eager to know, yes, I did get it into my collection and still wear it in rotation every week.

17. Seiko Prospex “Willard” SPB151

Seiko Prospex “Willard” SPB151

Another Seiko made famous and immortalized on celluloid in one of the greatest films of all time, Apocalypse Now (1979), is the Seiko 6105, which has been reissued much like the Arnie for modern consumers using modern materials in the SPB151 or the “Willard.”

For those who might not be a cinephile like myself, the SPB151 gets the Willard nickname after the main character of the previously mentioned film Apocalypse Now. Captain Benjamin Willard sports a Seiko 6105 for the entirety of the film, and it is because of the icon status that Seiko released the modern version, the SPB151.

With a case diameter of 42.7mm, a lug-to-lug distance of 46.6mm, and a case thickness of 13.2mm, the Willard is a downsized version of the original 6105, making it a joy to wear.

The Willard’s dial design is almost the exact same as its original counterpart, with the biggest differences being the Prospex logo and 200m printed on the dial.

The Willard has an MSRP of $1,300.

18. Seiko Prospex LX GMT SNR025

The LX GMT SNR025 is our final GMT on the list and one much like our last Seiko from the LX line; the SNR029 comes with a hefty price tag with an MSRP of $5,000

Like others in the LX line, the SNR025 utilizes the 5R66 Spring Drive Movement, meaning that this ultra-reliable and incredibly accurate GMT is capable of +/- 1 second per day. To put that into perspective, a COSC-certified movement needs to be accurate to +4 to -6 seconds a day!

The wonderfully finished titanium case has a diameter of 44.8mm, a lug-to-lug distance of 50.9mm, a case thickness of 14.7mm, and a rotating compass bezel, which gives this timepiece a rugged and adventurous look.

One thing that I haven’t mentioned yet in this article but pertains to and is used on every Seiko watch is their proprietary LumiBrite. This luminous material is brighter and more long-lasting than others. The application of LumiBrite means every Seiko watch glows like a torch in low-light conditions.

19. Seiko Prospex Solar Diver SNE591

Seiko Prospex Solar Diver SNE591

Much like our previously mentioned Solar Powered Sumo GMT, the Solar Diver SNE591 is an amazing option for a grab-and-go everyday watch that can handle any task you ask of it.

One of the standout features for the SNE591 is again going to be the power reserve from the solar-powered movement. When fully charged, the V157 movement will run for 10 months, which, again, is going to make a great watch for the enthusiast who doesn’t mind an alternatively powered timepiece. 

The “Pepsi” style dive time bezel is another great characteristic on this watch, with the red portion of the bezel from the 12 o’clock to the 15-minute marker indicating a final countdown for ascent to the surface.

With a case diameter of 42.8mm, a lug-to-lug distance of 49.2mm, and a case thickness of 10.7mm, this thin and uniquely powered dive watch has an MSRP of $525 but can be found brand new for under $400.

20. Seiko Prospex Solar Dive Chronograph SSC807

For our final entry on the list, we have another solar-powered timepiece, but one that packs a bit more functionality than the previous time-only Solar Diver.

The SSC807 is a dive chronograph that definitely packs some features into its stainless-steel case, measuring 44.5mm in diameter, with a lug-to-lug distance of 51.6mm and a thickness of 13.7mm, the most obvious being the 60-minute chronograph function.

The SSC807 is also equipped with a 24-hour hand, power reserve indicator, and a very useful rotating dive bezel. Personally, I find more use in timing things with the dive bezel than I do in an actual chronograph function.

With an MSRP of $750, the Solar Dive Chronograph is a great option for anyone looking for a dual-purpose sports watch. 


To sum it up quickly, Seiko dive watches represent innovation, adventure, and the entry point for millions of people into the obsession of watch collecting. Without Seiko, I wouldn’t be here writing this article; without Seiko, I’d probably never have done and seen the things I have just because I wanted to use my watch for its intended purpose.

So, with that, I just want to say thank you, Seiko; you’ve given me and millions like me a reason to look at our wrists and smile because behind every Seiko are memories that will last a lifetime.

BEST Seiko GMT Watches

Imagine the thrill of standing at the edge of an ancient citadel, gazing out over a sprawling metropolis as the sun sets behind distant mountains. Or picture yourself sipping espresso in a quaint café along a cobblestone street in a European city you’ve never visited before. 

These moments are the essence of travel. But as we go on exploring new cultures, we all need that one watch that will serve as our trusted companion, ensuring we never miss an appointment, a cultural event, or a flight back home. 

Fortunately, a GMT (Greenwich Mean Time) watch comes to the rescue. It is a type of timepiece that allows us to track multiple timezones simultaneously and has the power to transport us, not just through minutes and hours, but across oceans and continents.

These time-telling devices are valuable tools for travelers, professionals, and anyone who needs to stay connected with the world across different timezones.

Whether you’re an adventurer at heart, a globetrotter, or simply someone who cherishes the moments that make life unforgettable, here are 10 of the very best Seiko GMT watches that will not only mark hours but etch memories.

About Seiko GMT Watches

The concept of GMT watches can be traced back to the development of global travel, aviation, and the need for accurate timekeeping across different timezones.

For Seiko, the journey into the GMT realm began in 1964 with the launch of its first World Time watch – the  6217-7000 (MASWT). The World Timer could display the time in multiple timezones simultaneously and was powered by an automatic movement: the caliber 6217A. Its internal rotating bezel displayed 24 timezones, and the GMT hand came in either black or a warm sandy color.

A few years later, Seiko released the second generation of its GMT watches: the 6117-8000. The timepieces featured a bright-red GMT hand calibrated to the main hour hand and came in a stainless steel tonneau case that measured 38.5mm.

The highly functional GMT watch also featured a date window at 3 o’clock, a bezel with 24-hour denotations, and an automatic movement; the 6117A.

Seiko continued to innovate so that among its impressive repertoire, GMT watches have carved a niche for themselves. The brand produces a wide range of GMT watches, both mechanical and quartz, with various levels of complexity. 

In more recent years, Seiko has incorporated GPS technology into some of its watches so that the timepiece can automatically adjust to the correct local time using GPS signals. An example of this is the Astron GPS Solar LE | SSJ017.

Among Seiko’s impressive repertoire, GMT watches have carved a niche for themselves. Seiko GMT watches are popular among travelers, pilots, and professionals who frequently need to reference timezones worldwide. They are also useful for individuals conducting international business or communicating with colleagues or family in different timezones. 

What To Look For in Seiko GMT Watches?

When looking for a Seiko GMT watch, there are several key features and factors to consider to ensure you make the right choice:

Watch Style

GMT watches are not only functional devices but are also fashion accessories. Seiko offers a wide range of GMT watch designs, from sporty to dressy, so you have to find one that suits your taste.

Watch style is an essential consideration because it impacts the watch’s aesthetics and suitability for various occasions, comfort, and long-term satisfaction. Plus, if you choose a GMT watch that complements your style, you’ll be more inclined to wear and enjoy it.

Again, different occasions and settings call for different watch styles. If you attend many formal events, a dressy GMT watch with a sleek design is more appropriate. On the other hand, a sporty or rugged-styled GMT watch will be ideal for enthusiasts who often engage in outdoor activities or dress casually more often than not.

Additional Functions

Additional functions in a GMT watch refer to any features or complications beyond the basic timekeeping function. These functions are important to consider when buying a GMT watch because they can enhance its usefulness and versatility for various purposes. 

Some additional functions commonly found in Seiko GMT watches include a world time function (which allows you to view the current time in various cities around the world), a date display, and a chronograph.

If you’re a frequent traveler, you’d find the world time function of great importance. However, just a date function will do if you’re purchasing your GMT watch for everyday wear.


Seiko offers a wide price range, so there’s likely a GMT watch in its catalog for you. The prices often correlate with the watch’s features, materials, and craftsmanship, so set a budget before you explore Seiko’s GMT watch offerings.

By determining your budget, you can strike a balance between the features you desire and what you can afford. This helps you narrow down your choices and prevents you from overspending and regretting later on.

How To Read A Seiko GMT Watch

Before we get down to brass tacks, let’s shed light on an important issue: how to read your GMT watch. Setting up a GMT watch correctly for the first time and understanding how to adjust it can be confusing for some people, leading to occasional misreadings.

Here’s a step-by-step guide on how to read a GMT watch:

Identify the GMT Hand

Every Seiko GMT watch comes with three hands: the main hour hand, the minute hand, and the GMT hand. It is easy to identify because it’s always with a different design or color and points to a 24-hour scale on the watch.  

This GMT hand is what is used to track a second timezone. The main hour and minute hands on the dial only indicate the local time, just like any standard analog watch. 

Set The GMT Hand

You would find a 24-hour scale printed on the periphery of the dial of Seiko GMT watches or the bezel. This 24-hour scale helps you distinguish between AM and PM in the second timezone and is convenient for reading time in various settings, including military, aviation, and international timekeeping.

To set the GMT hand to the desired second timezone, use the watch’s crown to align the GMT hand with the reference timezone you want to track. Please ensure the bezel is in its correct position, with the 24-hour marker at noon.

Read the GMT Time

Once the GMT hand is correctly set, you can read the second timezone by noting where the GMT hand aligns with the 24-hour scale. Let’s assume that you’re traveling from Naples, Florida, to London, United Kingdom.

Before leaving, set the GMT hand on your watch to point to the current time in Naples. Naples, Florida, is in the Eastern timezone (ET), which is typically UTC-5 during Standard Time (EST) and UTC-4 during Daylight Saving Time (EDT).

Maintain the main hour and minute hands of your watch set to the local time throughout your journey, but as soon as you arrive in London, manually adjust the GMT hand on your watch to account for the time difference.

So if your home time is 09:00 on arrival, manually adjust the GMT hand on your watch to indicate 02:00 PM (14:00) as London is typically on Greenwich Mean Time (GMT), which is UTC+0.

This way, you can easily track the time in your reference timezone while keeping the local time on your watch without using phone apps or online converters.

So, choose your Seiko GMT watch, wear it proudly, and let it remind you that time, like life itself, is a precious journey meant to be cherished, celebrated, and savored to the fullest.

Seiko Metronome Watches

Metronomes are an essential tool for musicians. Playing in time is one of the fundamental skills necessary to be successful in performing almost any style of music, let alone getting called to perform with others. 

To practice this, musicians often rely on metronomes to provide a steady pulse to practice to, and illuminate their mistakes. Because of this, metronomes are sometimes referred to as one of the great equalizers in the field of music. 

Metronomes function by making a noise at a steady rate, which is set by the user. For example, if practicing a piece performed at 140 bpm (beats per minute), the user would set their metronome to that pace and attempt to perform the passage at that pace. Depending on what needs to be addressed and the user’s goal, they may slow or speed up the metronome.

Conventional metronomes you may have seen on a relative’s piano required a mainspring to be wound, and a counterweight would be used to adjust the tempo. More modern ones are digital devices that are pocket-sized and easily fit in instrument cases. With that, there are great apps for smartphones today that are powerful metronomes with extensive tools that aid musicians in their practice routines.

For watch enthusiasts, there are some overlaps between watches and metronome devices. Patek Philippe made a metronome pocket watch around 1880. Cadenzia Palmer also made one that was much more mass-market, and examples can still be found today. However, to the best of my knowledge and research, there has not been an analog display wrist-worn metronome watch until the Seiko Metronome watches released in 2022.

About Seiko Metronome Watches

Seiko Watch Company actually does not produce these watches. Seiko Instruments is responsible for the manufacturing of the Seiko Metronome watches, along with a myriad of technology products. Seiko Instruments has a long history of making metronomes, including conventional mechanical metronomes. 

For the watchmaking component, one may think that Seiko Instruments may be out of bounds making a watch and that they may rely on Seiko Timepieces for that portion. While there probably is some overlap, Seiko Instruments makes clocks in various sizes and with numerous functions, meaning there is plenty of know-how within Seiko Instruments to pull off this impressive watch. 

The Seiko Metronome watches are obviously a unique proposition in the watch world, given the quirky set of complications. For musicians, they propose a handy set of tools to be worn on the wrist. Punctuality for rehearsals and concert call times is essential. 

A metronome, as already described, is a valuable practice tool. Given its ability to mark tempos from 40 bpm to 304 bpm, it allows for a wide variety of practice speeds, in addition to noting smaller note values at slower tempos. 

For example, you could set the metronome at 240 bpm to mark eight notes and 120 bpm. There is also a tuning pitch function, sounding an audible pitch that can be set to A or Bb. You can also adjust the pitch of the A to 440 Hz, 442 Hz, or 443 Hz. 

In-Depth Guide to Seiko Metronome Watches

To cover the more conventional aspects of the Seiko Metronome watches, here are the technical aspects of these unique timepieces.

Case Dimensions

The Seiko Metronome watches measure 36.5mm wide, 39mm lug-to-lug, 10mm thick, and have 18mm lugs. The compact dimensions make them suitable for a wide audience and a number of situations. 

With the design being mostly the dial, it will fill space on the wrist more so than the case dimensions may suggest. The case is rated for daily-use water resistance, which means it can only handle daily hand washing and being caught in a rain storm while on the wrist. 

Model Variations

There are two main dial designs split between two lines: the standard line and the casual line. The standard line has more markings for the metronome, offering more accurate measurements of tempos. The casual line has more colorful dials and fewer metronome markings. Below are the various models separated by product lines. 

Standard Line

SMW002A: White dial, rose gold case, white strap

SMW005A: Turquoise dial, gold case, beige strap

SMW006A: White dial, steel case, black strap

SMW003A: Silver dial, gold case, brown strap

SMW004A: Blue dial, black case, blue strap

SMW001A: Black dial, gold case, brown strap

Casual Line

SMW004B: White and blue dial, steel case, blue strap

SMW001B: White and black dial, steel case, black strap

SMW002B: Pink and white dial, gold case, white strap

SMW003B: Purple and white dial, gold case, white strap

All of the various models come with calf leather straps. There are also special editions with different straps to change the overall look and formality of the watch. 


With the various functions of this watch, it is likely best to look at the owner’s manual to fully understand how to utilize the watch. That being said, here is a brief overview of how to operate the various functions.  The pusher at the lower left side of the watch (8 o’clock) is the function button.

Each press cycles between the different functions. Assuming one is starting in the time-telling mode, a single press puts the watch into metronome mode. Both hands will move to 12 o’clock, and the minute hand will start oscillating back and forth to indicate the desired tempo. 

The hour hand will move to the indicated tempo. The upper left pusher (10 o’clock) controls the audible click for the metronome, and the pushers on the right-hand side of the case (2 o’clock and 4 o’clock) control the tempo. 

The next mode is the pitch mode, with the two pushers on the right-hand side of the case used to cycle through the different pitches. 

To set the time, a long press on the 10 o’clock pusher starts the time setting mode, with the two pushers on the right side of the case used to adjust the time. Another press of the 10 o’clock pusher sets the time, and the watch will begin to run. 


Inside the Seiko Metronome watch is the quartz caliber PA50, which runs on a standard CR 2016 battery that is rated for 2 years. The movement is rated to an accuracy of +/- 15 seconds a month. 

On the Seiko Instrument Japan website, there is a brief explanation of the two specially designed motors for the hands, allowing them to move in both directions for the metronome functions. It is clear that some clever engineering was involved in creating this watch. 

Seiko Metronome Watches Pricing & Availability

Even though the Seiko Metronome Watches have proven popular amongst watch enthusiasts, their availability is limited to the Japanese market. Platforms such as eBay will facilitate global powers being in touch with Japanese dealers, but these platforms may charge a premium above the 26,400 JPY retail price (about 180 USD at the time of writing). 

In addition to the limited market availability, they seem to sell out quite quickly, but with the promise of more being available. With patience, securing a Seiko Metronome Watch should not be too difficult. 

Should You Buy a Seiko Metronome Watch?

As with almost any watch, if it is affordable and interesting, there is no reason why someone should not buy one! With its fun design and complications, it will likely provide some levity to one’s watch collection. 

For musicians who are also watch enthusiasts, a Seiko Metronome Watch will probably be a frequently worn and used watch in their collection. While apps may be more immediately useful, watch enthusiasts know that there is something charming about a more analog wrist-worn experience.


It is always exciting when a watch company releases a unique product, and Seiko Instruments definitely did so here. While its intended use is only immediately practical to a relatively small audience, watch enthusiasts, in general, will likely enjoy interacting with the metronome function. 

Seiko Instruments did a great job of designing an attractive watch while incorporating the indications needed for the metronome and tuner functions. If one is willing to do the extra leg work of locating one, the affordable price makes them attainable to a wide audience.

skx007 vs skx013

If you’re standing at the crossroads of Timepiece Avenue and Decision Lane, you’ve come to the right place. Think of this as a battle of the Titans; instead of clashing on Mount Olympus, they’re vying for space on your wrist. Choosing between a Seiko SKX007 and SKX013 is a decision that demands more than just a coin flip. 

Why? Because they’re both legendary pieces with unique styles and strengths. With the SKX007, you’ve got the quintessential dive watch – a chunky and reliable timepiece. On the other hand, the SKX013 offers a subtler, more compact take on the classic design. Which one will be your go-to? The bold SKX007 or the understated SKX013? 

Not to worry – I’m not here to swing your vote in favor of one or the other. Instead, I’ll arm you with all the sumptuous details you need to make an informed decision. We’ll look closer at the aspects that set these two Seiko gems apart: case dimensions, wearability, dial proportions, hands, and strap options. So, let’s get to it.

About The Seiko SKX

The Seiko SKX collection is like the original Star Wars trilogy. It has its stalwarts, each with a distinct personality and set of fans. The group’s Darth Vader is the SKX007 — a mean-looking watch with its sleek black dial and versatile persona.

Then comes the SKX009, the “Luke Skywalker,” with its “Pepsi” blue and red bezel. Ideal for those who like a splash of color or a solid alternative to Rolex’s soda-themed GMT Masters. It’s the same classic design as the 007 but with a more playful edge.

Last but not least is the SKX013, the Yoda of the trio. It’s smaller and subtle but boasts the same horological finesse as its larger counterparts. If the 007 and 009 are your weekend warriors, the 013 is your everyday sage.

While some watches can dive deeper than the Mariana Trench, they cost more than a semester at an Ivy League school for the most part. But the Seiko SKX, with its ISO 6425 certification, water resistance up to 200 meters, and automatic movement with its affordability, tops them all.

Perhaps the most appealing aspect is its accessibility – they cost a couple hundred dollars and are readily available at retailers.

History Of The Seiko SKX

The history of the Seiko SKX dates back to 1996, when dial-up internet was all the rage and “Friends” had just started dominating TV screens. Seiko unleashed the SKX series onto an unsuspecting world, and the series has become a mainstay in the world of dive watches. 

It would seem that Seiko’s mission was to create a dive watch that was dependable, versatile, and affordable. Hence, the Seiko SKX was born – a timepiece featuring an automatic movement, a day-date window, and water resistance up to 200 meters. Talk about an overachiever, right?

Now, you might be wondering why it garnered such cult-like devotion. Well, it’s not only for its sophisticated appearance. It also delivered on performance. We’re talking ISO 6425 certification and an automatic movement that made it as accurate as a Swiss watchmaker’s ruler.

And the best part? You didn’t need to be a hedge-fund manager to afford one. But all good things must come to an end. In 2019, after more than two decades of being the darling of the dive watch community, Seiko decided to discontinue the SKX series.

Why did Seiko do it? Probably to make room for new models, or the SKX had reached its endgame, with its arc complete and its legacy assured. Either way, today, the Seiko SKX enjoys its status as a modern classic. New models, like the Seiko 5 Sports, attempt to fill the SKX’s rather large shoes. But for many, the original will always have a special place in their hearts.

SKX007 vs SKX013: The Similarities

The SKX007 and SKX013 are like two peas in a pod. They share the same features and are so closely related that you’d think they were separated at birth and reunited at a watch convention. In fact, choosing between them is like picking a favorite child; it’s best not to, or at least not to let the other one find out.

Here’s what makes these Seiko siblings so similar.


When it comes to materials, the SKX007 and the SKX013 are as identical as two parallel lines that decide to take a nap on the same geometric plane. Both models come in stainless steel cases, strongly built to handle more than just the occasional accidental knock against the door frame.

And like true dive watch models with stainless steel cases, they’re also incredibly lightweight. So whether you’re dodging coral reefs or office desk corners, these models are up to the task.


The SKX007 and the SKX013 share a unidirectional rotating bezel with the kind of satisfying click that ASMR artists only dream about. Both bezels are so similar that it’s as though one bezel said to the other, “I want to be just like you when I grow up”.

They can be your underwater timer, makeshift egg timer, or even your “how-long-until-I-have-to-get-back-to-reality” timer.  There are no differences here – save for the bezel in the SKX013, which is slightly smaller than the SKX007.


Have you ever had a wrist accessory that required you to summon the strength of a Greek god just to set the time? Fear not! 

The screw-down crowns are located at the 4 o’clock position on both models, ensuring that your time-telling endeavors are a breeze. Easy to grip and pleasing to the touch, their crowns are the quintessence of usability. Simply pull out and turn the crown clockwise to adjust the time and date, and push the crown right back in to ensure a watertight seal.


Still, on the similarities, let’s talk about the crystal – a watch’s window to the world. Both SKX models come equipped with Seiko’s Hardlex crystal. The Hardlex crystal is probably Seiko’s answer to the “How can we make this thing as sturdy as Captain America’s shield?” question.

Sure, it is not a sapphire crystal, but neither watch is pretending to be the Hope Diamond of wristwear. They’re hard, durable, and incredibly similar in their scratch resistance.


Last on our list of similarities, let’s talk about what makes these watches tick. Beneath the rugged exteriors of these Seiko siblings lies a shared heartbeat – Seiko’ very own Caliber 7S26 automatic movement. This movement boasts a day/date complication, 21 jewels, a 43-hour power reserve, and a 21,600 bph.

Recently, Seiko diver models have been powered by the 4R movements, which come with hacking. So, if you’re a purist keen on getting the original movement, it is advised that you are a lot more vigilant during purchase.

SKX007 vs SKX013: The Differences

The saying “no two people are alike” doesn’t just apply to people. It also holds when evaluating the features of twin or sibling watches like the SKX007 and its charming counterpart, the SKX013. 

Both watches steer their course with captivating and uniquely appealing features. Note, though, that these differences, albeit minute, can swing your vote in favor of one another. So, here are the aspects in which the SKX007 and the SKX013 differ:

Case Dimensions

If size matters to you, pay close attention because this is where the SKX007 and SKX013 begin to differ. The SKX007 is the big brother (literally) of both watches, with a case diameter of 42.5mm, while the SKX013 is smaller at 38mm

Think of it this way: the SKX007 is the Dwayne “The Rock” Johnson of this Seiko pair – bold and impossible to ignore. The SKX013, on the other hand, is more like Joseph Gordon-Levitt, slightly more understated but no less captivating.

There is only a 1mm difference in case thickness, so there is no wide disparity in weight. However, if you’re a member of the “bigger is better” clan, you’ll be inclined to purchase the SKX007. And if you fancy small, or should I say “standard” dive watch sizes, then go for the SKX013 model.


Because of the size difference, wearability becomes an intriguing debate. If you have larger wrists, the SKX007 wraps around like it was always meant to be there. The SKX007’s broader case exudes a robust aura, perfect for those who embrace wrist presence with open arms.

But if your wrists are slender and you wear the SKX007, it might look like you’re a kid playing dress-up with your dad’s watch. Again, if you are a fan of big watches, this is not necessarily a bad thing, so long as you wear it well.

Conversely, the SKX013’s compactness ensures a snug fit as comfortable as a sailor’s hammock. The SKX013 sits more comfortably on smaller wrists and doesn’t shout for attention. But don’t underestimate it. Much like a cat waiting to pounce, its appeal is in its subtlety. It’s all about how you want to rock your maritime flair – bold or understated.

Dial Proportions

Aside from the case, the next obvious set of differences presents itself in the dial. This disparity is because although the Seiko models come in different sizes, they are powered by the same movement. Thus, the SKX007 has a larger dial proportion, with each element from the indices to the day-date window enjoying a little more breathing room.

The SKX013, although smaller, manages to fit everything without making it look like a cramped New York subway car during rush hour. The smaller dial does mean everything is just a tad closer together, so if you’re a fan of personal space, this is something to consider.


Both watches’ hands are styled similarly but scale differently to fit their respective dials. But beyond the room on the dial, subtle differences in its elements are only visible to the keen eye.

For instance, the hour and minute hands of the SKX007 are a lot thicker, with sharper edges and more intense lume application, allowing for brighter visibility in low-light conditions. The hour hand of the SKX013 features a gradual tapering to its arrowhead, while the SKX007 boasts a sharp arrowhead with a broader base.

Additionally, the second hand of SKX013 has a distinctive design with a thick, tapered tip and base, contrasting the slim design and black base of the SKX007’s second hand.

Strap Options

Both watches come with a variety of strap options. Well, not so much of a variety – you get to choose between the stainless steel Jubilee metal bracelet and the Seiko “Wave” rubber strap. However, the SKX007 offers a beefier bracelet, which can be a bold style statement due to its larger size. 

The SKX013 has similar options but scaled down to match its size, providing a more classic look. Think of it as the difference between wearing combat boots or loafers. Both are footwear, but the impression they create couldn’t be more different.

What About The SKX009?

The Seiko SKX009 model embodies the presence of the SKX007 and the SKX013 – it’s modest and unassuming with an aura that announces itself. It is the cherry (or Pepsi) on top of the SKX series sundae. Yeah, that’s our “Pepsi” bezel hero.

You see, while the SKX007 and SKX013 come in elegant black bezels, the SKX009 decided to up the ante with a Pepsi-colored red and blue bezel. It’s a mind-boggling color combo that screams, “Look at me!”. Yet the red and blue combo isn’t just eye candy; it serves a purpose for divers by offering a visual cue for elapsed time, making it both functional and fabulous.

Even if you didn’t, Seiko was ready to go over and beyond with this watch by switching up the dial from the conventional black in the SKX007 and SKX013 models to a blue in the SKX009 model. 

In terms of the size, the SKX009 shares its 42mm diameter casing with the SKX007. So, if your wrist can rock the latter, it can carry the former. But hey, big or small, there’s an SKX for all – no SKX009 for small wrists, though.

Also, the SKX007 and SKX009 offer options for rubber straps or metal bracelets, giving you the versatility to go casual or formal. The SKX013, on the other hand, prefers to come with a rubber strap – like its own personal choice of being a bit more understated.

Aside from the differences already stated, however, the other features of the SKX009 are similar to those of its siblings, the SKX007 and the SKX013. In essence, the SKX009 model is powered by the Seiko Caliber 7S26 automatic movement and sports Seiko’s Hardlex crystal and luminesce coating.

SKX007 vs. SKX013: Which Should You Choose?

Choosing between the Seiko SKX007 and SKX013 is always challenging, except for people whose choices are influenced by case dimensions. If you are a watch enthusiast, saying no to a Seiko is like refusing a free ticket to Disneyland, Hogwarts, or Narnia. You get the idea.

Both models have a die-hard following and are highly functional. We’re talking about water-resistant, stainless steel marvels with a unidirectional bezel and that classic “take-me-seriously-I’m-adventurous” look.

These watches say you can wrestle a bear in the morning and negotiate a merger by afternoon (PS: please don’t try wrestling a bear). Since both models are so awesome, we are back to the question, “Which SKX model should you choose?” And here’s my take:

If you have wrists like tree trunks or your personality can only be described as “the life of the party,” go for the SKX007. Its 42mm case screams attention but in a sophisticated, “I-read-The-Economist” way. Moreover, the larger dial means it’s easier to read the time even if you’re squinting through fogged-up diving goggles 100 meters underwater.

However, if you’re the quiet genius type who knows seven languages and can solve a Rubik’s Cube behind their back, you don’t need to shout; your accomplishments speak for themselves. The SKX013 is your perfect match. Its 38mm case, it’s not as shouty as its counterpart but still commands respect.

SKX007 vs SKX013: Pricing & Availability

When buying an SKX model, the pricing really shouldn’t be a bother. You’re buying a Seiko here, not Patek Philippe. That means you won’t have to mortgage your home, sell your car, or enter a blood pact with a mysterious stranger to afford one. But don’t get too comfortable.

First off, a heartbreaking fact: Seiko has officially discontinued both models. Yup, it’s like learning that your favorite TV show won’t be returning for a new season. But don’t lose hope; like DVD box sets and Netflix reruns, new and used versions of these classic divers can still be found if you know where to look.

If you’ve got your heart set on a brand-new SKX007 or SKX013, you’ll be hunting in the wild terrains of authorized dealers with leftover stock. Expect to shell out around $300 to $450 for a new SKX007 and around $250 to $400 for a new SKX013.

Now, if you appreciate a good “pre-loved” or “fairly-used” item, the used market has its own set of rules. On various auction sites and forums, you can find a used SKX007 for around $200 to $350 and an SKX013 for approximately $180 to $300. 

Of course, those prices are as variable as a cat’s mood, depending on factors like condition, age, and whether the seller thinks they’re parting with a family heirloom or just a watch.


In sum, the Seiko SKX007 and SKX013 offer an excellent introduction to the world of automatic dive watches, embodying durability, functionality, and timeless design. The core difference lies primarily in the case size, making the SKX007 more suited for those with larger wrists or who prefer a bolder wrist presence. 

On the other hand, the SKX013 serves well for those with smaller wrists or who favor a more subtle look. Both models boast similar features like the reliable 7S26 movement, ISO-rated water resistance, and a day-date complication.

The decision boils down to personal preference in size and wrist comfort. Either way, you’re investing in a watch with decades of Seiko’s horological expertise, offering both form and function that will serve you well whether you’re 200 meters underwater or simply going about your everyday life. Choose the one that speaks to you, and you’ll have a reliable timepiece that stands the test of time.

Should You Buy Seiko's Tank Watch?

In the world of horology, few timepieces command the same reverence and admiration as the Cartier Tank. Like a bridge connecting the realms of art, design, and precision engineering, the Tank watch stands as an emblem of enduring elegance. 

However, owning one of the most distinctive dress watches ever made comes at a high price. There’s also the problem of limited availability due to high demand, and this is where the Seiko Tank watch steps in.

By creating its version of a Tank watch, Seiko pays homage to this uncharted horological territory. This allows a broader range of consumers to experience the elegance and charm associated with this historical timepiece at a more accessible price point.

Let’s take a closer look at Seiko’s interpretation of the iconic tank-style watch and whether you need one in your collection.

About The Seiko “Tank” Watch

The Tank watch design was born in the early 20th century when Louis Cartier was inspired to design an eccentric dress watch.

The geometric aesthetics of the watch were based on the utilitarian appearance of the tracks of an armored combat vehicle, such as the Renault tank. 

Cartier’s Tank pioneered the rectangular watch style, and other brands have taken inspiration from it to create their unique interpretations. One of these brands happens to be Japanese giant Seiko.

The particular date when Seiko started introducing rectangular watches similar to the ‘Tank style’ is unknown. However, it was in the 1970s that the brand gained significant attention for its watches with rectangular cases, such as the Ref.4120-5010 and Ref. 7830-5000.

These timepieces were successful because they offered a departure from the traditional round watch shape, allowing for creative and varied designs that appealed to different tastes and preferences.

Seiko continued producing these eccentric dress watches, and in the late 2010s, one of the brand’s most popular ‘Tank-inspired’ watches, the SUP880, was released. The SUP880, which will be our focus today, is heavily inspired by the Cartier Tank‘s design, leading to it being nicknamed ‘the Tank.’ 

The watch captures the essence of the Tank’s appeal while offering additional perks such as solar movement and affordability.

The Seiko SUP880 garnered a lot of popularity and appreciation among watch enthusiasts due to its timeless design, high-quality craftsmanship, and fitting case dimensions.

The Tank is a basic timekeeping watch with no additional complications. It boasts a minimalist and understated design, which makes it an ideal accessory for formal events or professional settings.

The watch features a stainless steel case and a minimalist dial with simple hour markers and hands. The rectangular-shaped timepiece is worn on a slim leather band and is powered by the reliable V115 in-house solar movement.

Since the Tank is primarily designed for dressier occasions, it has a limited water resistance of just 30 meters (100 feet).

History of Seiko Watches

Now that you know a bit about the Seiko Tank, let’s quickly take a broader look at the history of Seiko and its innovations in the watch industry. Seiko, founded in 1881 in Tokyo, Japan, started as a small shop by Kintarō Hattori that sold and repaired clocks and watches. 

In 1913, the young brand produced its (and Japan’s) first wristwatch, the Laurel. Eleven years later, the first watch with the Seiko brand logo was released.

The company continued to innovate, developing Japan’s first pocket watch with a chronograph in 1941 and the country’s first automatic wristwatch, ‘the Automatic’ in 1956.

Seiko made significant advancements in the 1960s and 1970s, too. In 1969, they introduced the Seiko Astron, the world’s first quartz watch, marking a significant shift in timekeeping technology. The 1970s saw the creation of iconic models like the Seiko Quartz Diver 7549 and the Seiko 5 series.

Other Seiko’s contributions to horology include the creation of the first digital watch with a six-digit display, the Seiko Quartz LC V.F.A. 06LC, in 1973. The Seiko Kinetic was launched under the name A.G.S. in 1988, a watch that converts kinetic movement into electrical energy. Seiko’s commitment to innovation continued, and in 1999, Spring Drive technology, known for its exceptional accuracy, was introduced.

The company’s dedication to precision led to Seiko’s involvement in various sports events as the official timekeeper, including the Olympics. The brand also played a pivotal role in the development of technical innovations, including several watches with computing capabilities.  

Seiko has maintained a reputation for precision, durability, and cutting-edge technology throughout its history. The company’s various lines, such as Grand Seiko (which is now fully an independent watch brand) and Prospex, cater to different markets and offer a wide range of designs and functionalities.

Overall, Seiko’s rich history is marked by continuous innovation, from its early days as a clock and watch shop to its status as a global leader in watchmaking, known for its exceptional craftsmanship and technological advancements.

Seiko “Tank” Watch: In-Depth Review

It’s over a century since the first Tank watch took the watch world by storm. Despite the ebbs and flows of fashion trends, the timeless appeal of ‘the Tank’ has not ceased to captivate millions of enthusiasts around the world.

The Seiko Tank is no different and resonates with thousands of consumers who value a unique and distinctive look compared to more common round watches.

But why the enduring appeal?  Let’s answer this by taking a closer look at the SUP880, which pays homage to the Cartier Tank watch while infusing unique Japanese craftsmanship.

Dimensions & Wearability

The dimension and wearability of the Seiko SUP880 is a fundamental element that contributes to its enduring appeal. The case profile is pretty low at around 38mm lug to lug and 28.4mm in diameter. Lug-to-lug is the distance from the edge of one lug (or horn) to the corresponding one on the other end of the case.

Historically, dress watches were designed to be thin so they could fit seamlessly under a shirt sleeve. This design principle has been carried through here, maintaining the association of thinness with formal elegance. The slim profile of 6.1mm makes it comfortable to wear, especially for extended periods, without feeling bulky or obstructive.

The lugs are straight, and there’s no curvature of the case back, so the proportions of the SUP880 are a bit larger. However, this doesn’t affect wearability as rectangular watches do provide a more snug fit on wrists due to their longer case.

It’s worth noting that the Tank was originally designed as a unisex watch, which means that its proportions are generally well-suited for both men and women. However, there is a smaller version, the SUP250, which measures 26 mm x 18 mm x 6 mm (LxWxH).

The strap width is 22mm, and the length is men’s standard. The watch is, thus, suitable for wrist sizes around 7 inches.

Build Quality & Durability

Seiko has a reputation for producing reliable timepieces that can withstand regular use and last for many years. While the Tank might not have the same level of craftsmanship as higher-priced models from the brand, the build quality and durability are spot-on.

As a matter of fact, you’ll be hard-pressed to find a sturdy and reliable ‘Tank-inspired’ watch at this price point.

The SUP880 features a stainless steel case and mineral crystal for the protection of the dial. While not as scratch-resistant as sapphire, mineral crystal is still quite durable and can withstand minor impacts without easily shattering.

The case is made of 316L stainless steel, which offers good corrosion resistance and durability while maintaining an affordable price point. The case is further coated with gold to provide aesthetic enhancements and offer additional protection against scratches and tarnishing.

Even though the Tank is an entry-level watch from Seiko, the robust construction, high-quality materials, and reliable manufacturing technique make it a very durable timepiece. The case also shows off a radiant, polished finish and comes with a thick fixed bezel, which gives the watch a sturdy impression. 


Seiko’s Tank watch features a clean and uncluttered dial layout. The focus is on simplicity and elegance, with a balance of negative space and functional elements.

The dial has a railroad-style minute track below the Roman numeral hour markers, which lie along the outer perimeter. This detail enhances legibility, adds a touch of vintage charm, and further emphasizes the watch’s timeless and traditional aesthetic. 

The numerals are printed in a bold, black font, and two thin Feuille hands are attached to a gold-colored center. The absence of excessive embellishments, complications, and texts contributes to the watch’s timeless aesthetic.

There is also no seconds hand, and the white background of the dial is finished with faint gray horizontal stripes. These delicate gray stripes lend an air of sophistication and depth to the otherwise pristine composition of the dial.


One of the standout features of the SUP880 is its solar-powered movement, the in-house V115, with an accuracy rate of +/- 15 seconds per month. The V115 solar quartz movement works by harnessing light energy to power the watch. It has a solar panel on the watch dial that captures both natural and artificial light. 

This light is then converted into electrical energy, which is stored in a rechargeable battery within the watch. This eliminates the need for frequent battery replacements, as the watch can keep running for years with continuous exposure to light. It can last for up to 12 months when fully charged.


The Seiko SUP880 is paired with a black calfskin leather strap stamped with a crocodile pattern. The strap is made from high-quality leather, offering a luxurious and elegant feel. 

Most users complain that the leather strap is hard and stiff, but you can try softening it by using leather conditioner or oil specifically designed for leather goods. 

Just apply a small amount to the strap and massage it gently. Let it sit for a while, and wipe off any excess. This should help restore some flexibility to the leather, but be cautious not to overdo it, as excessive conditioning can damage the strap.

Back to the description of the strap, it has a smooth texture, meticulous stitching, and a gold-tone stainless steel pin buckle. The buckle matches well with the Seiko SUP880’s case and helps keep the watch securely fastened to your wrist.

Should You Buy A Seiko “Tank” Watch?

Whether you should buy a Seiko Tank watch depends on your style and preferences. I believe it’s better to invest in the authentic and original Tank that respects the craftsmanship and design of Cartier, which is the brand that created it. 

However, the SUP880 Tank watch is a good option for those who are looking for a more affordable alternative to the luxury Cartier Tank.

While Seiko Tank watches might not have the same prestige as those from Cartier, they offer good quality and value for their price. This makes them a practical choice for individuals who appreciate the tank style but have a more modest budget.

The Tank watch’s versatility, ability to complement both formal and casual attire, and its place in horological history make it a captivating choice for watch enthusiasts and those who appreciate enduring styles.

Seiko “Tank” watch Pricing & Availability

Seiko Tank watches are widely available and can be found in numerous retail stores, both physical and online. You can purchase the SUP880 from official Seiko retailers, authorized dealers, and various e-commerce platforms. 

At the time of writing this article, the Tank watch retails for US$180 MSRP on Seiko’s website. Prices for a pre-owned Seiko Tank watch depend on its condition and fall between 160 and 290 USD.


Seiko Tank watches combine a timeless design with reliable Japanese craftsmanship and offer an accessible entry point into the world of tank-style timepieces.

Those who value a blend of affordability and elegant design might gravitate toward Seiko, while enthusiasts seeking a prestigious statement piece would find Cartier Tank watches more appealing. 

Whichever path is chosen, both Seiko and Cartier have left an indelible mark on horological history through their respective interpretations of the iconic tank-style watch.
