It’s no longer news that Seiko produces some of the best wristwatches on the market. Thus, it is understandable that the brand collaborates with PADI, the world’s largest diving network. Over time, these two have collaborated to produce some of the best Seiko PADI watches. These wristwatches have gained recognition by the best of the divers.

It is quite interesting that this collaboration has birthed several outstanding timepieces. Some people even think of Seiko and PADI as a single company. However, these companies are not the same. In this article, we will look at the best Seiko PADI wristwatches. Additionally, we will consider the Seiko and PADI collaboration and how it has impacted the diver watches industry.

What is PADI?

The Professional Association of Diving Instructors (PADI) is the world’s largest diver organization that deals with ocean exploration. The organization operates in 186 countries and has more than 6,600 resorts and dive centers globally. Additionally, this organization has more than 128,000 members scattered all over the globe. PADI has influenced the diver community for more than half a century. The brand is renowned for its high dive training standards, safety, and customer service.

With such influence, it was only logical for PADI to team up with one of the world’s most renowned watchmakers, Seiko. Seiko is a household name for professional divers who want the best features in their dive watches. Recently, Seiko released a new PADI collection that features the official logo and brand colors. Hence, the collection makes it the first divers watch with PADI’s credentials on timepieces. We will consider some of the most prominent Seiko PADI timepieces available for divers and watch enthusiasts.

You would be forgiven to think that Grand Seiko and Seiko are the same watches. Seiko is a popular brand but many people confuse it with the watch’s big brother – the Grand Seiko. Seiko watches have the reputation of being reliable, durable, and affordable. They are the watches to go for when looking for a quality and luxurious watch on a budget.

People who have been fortunate to come across both Grand Seiko and Seiko watches understand that although the two watches may look similar, there is a world of difference between them. The Grand Seiko came to cement Seiko’s place as a solid luxury watchmaker that commands the industry’s respect while still producing affordable watches.

It is no shock then that the Grand Seiko is ten times more expensive than a normal Seiko (such as the Presage). The lingering question here is: Why? What makes the Grand Seiko so unique? What is the difference between this watch and a Seiko watch you can grab off a street vendor for a few hundred bucks? This is what we seek to demystify here. Read on to learn the difference between the Grand Seiko and the Seiko watch so that you can make an informed decision the next time you think of buying a watch from the Seiko Company.

Seiko as a company – brief history

Before we compare the two watches, let us explore more about the company that manufactures these incredible watches. Seiko is among the oldest watchmaking companies in the world. The company traces its root to Tokyo, Japan, when Kintaro Hattori, a 21-year-old entrepreneur opened a shop selling watches in 1881. The company started producing and selling wall clocks before evolving into the production of pocket watches in 1895.

Kintaro was inspired to start the watchmaking company by the abandonment of the old ways of timekeeping in Japan. People needed a more reliable and accurate way of keeping time.
The pocket watches from Seiko paved the way for the production of the first wristwatch – the Seiko Laurel – in 1913. The first Seiko watch was produced in 1924 under the brand name ‘Seikosha’.

It was an instant hit and this was the watch that would shape the company’s heritage and establish dominance in the watchmaking industry. Over time, after a lot of improvements on the Seikosha watch, the first Grand Seiko model was manufactured in 1960. This was the company’s signature piece and it cemented Seiko’s place as a premium watchmaker.

Other models were released over the years, including Japan’s first wristwatch to have a stopwatch in 1964, and the first Japanese Diver’s watch in 1965. For over a century Seiko has continued to rebrand itself, adopting emerging technology to create fascinating timepieces that resonate with the masses. In 2017, Grand Seiko became an independent brand, setting itself apart from the company to mark its uniqueness and superiority as the best Seiko watch model.

As an independent brand, the Grand Seiko was able to penetrate other markets beyond Japan and establish itself as one of the best and among the most affordable luxury watches one can buy.
In the ensuing paragraphs, we shall compare the two watches deeply to understand what makes the Grand Seiko unique and more pricey than the Seiko watch.

Which watch should I go for – Seiko or grand Seiko?

Seiko creates watches that match almost every customer segment. Whether you can afford a Seiko or Grand Seiko, you will be proud to own either. The price point is what will eventually determine which watch you go for. But do not be fooled. There are distinct differences between a Seiko watch that you can purchase for several hundred dollars and a Grand Seiko that commands thousands of dollars.

Comparison of Grand Seiko and Seiko Movements

The Grand Seiko uses spring drive technology. The spring drive technology revolutionalized the watchmaking industry, placing Seiko on the same level as its competitors – The Swiss luxury watchmakers. This technology was invented by Yoshikazu Akahane, one of the world’s highly skilled watchmakers, in 1977. His main goal was to combine the best system from a quartz watch and a mechanical watch and create a unique product.

History tip: To understand how spring drive watches work, let’s quickly explore the evolution of watchmaking. The first batch of watches made in the mid-20th century were mechanical watches. These watches utilized a system where the movements inside worked through a distribution of stored energy via a gear train.

The main spring (located inside a barrel in the watch) was wound to coil tightly and then with the help of the barrel it could pass small releases of energy through the unwinding process. Despite the obvious advantage of not needing an external power source to keep this watch working, any disturbance to the oscillation (temperature, friction, etc) could make the watch gain or lose time easily.

In 1969, Seiko came up with the quartz-powered watch. This battery-powered device solved the limitations contained in mechanical watches. The quartz watches were more accurate than mechanical watches and they could be manufactured en masse easily. A simple quartz watch could outperform an expensive mechanical watch.

The spring drive technology idea came to tap into the super accuracy of the quartz watch with the endless power supply of the mechanical watch. 28 years later and with over 600 prototypes, the first batch of spring-drive watches was available for sale to the public in 2005. Similar to mechanical watches, the spring drive is powered by the uncoiling of the mainspring that gradually releases energy. However, instead of the typical escapement, these watches have a revolutionary tri-synchro regulator component installed.

The tri-synchro regulator does 3 functions;

  • It helps to control the release of energy from the mainspring
  • It assists in the conversion of the mechanical power from the mainspring to electrical power energy to the quartz
  • It generates a magnetic force to act as a frictionless brake to ensure accuracy in timekeeping

The electrical charge generated in the glide wheel is sent to the quartz crystal to create a vibration and then sent back to the integrated circuit. Instead of the constant locking and unlocking mechanism found in a quartz watch, we get a quartz oscillation frequency. Free rotation of the glide wheel allows for the beautiful movement of the second hand. The hand seems as if it is floating.

Quality, style, and build of Seiko Vs Grand Seiko

When you place the Seiko watch and the Grand Seiko watches side by side, you will notice several craftsmanship differences. The Seiko watch was designed to be an incredibly accurate yet affordable timepiece but it has nothing over the Grand Seiko. The casing does not have the luxurious look or feel of the Grand Seiko. We shall explore these structural differences between the two watches briefly in the preceding paragraphs.

Grand Seiko watch parts are handmade

There is a certain level of sophistication that comes with creating a product by hand versus using a machine. Seiko watches may be reliable but the company does not put much effort (or money) into designing these watches. And the price point reflects this. You can pick a Seiko watch for approximately $500 from a street vendor.

Grand Seiko watches demand a higher price point (with some selling for over $15,000 a piece). Why the huge price variation? Many components of the Grand Seiko watches are made by hand. Japanese watchmakers have an unrivaled reputation for being legends in their business.

It is not uncommon to find a person working on a single watch component for over a decade. Combine several experts, each with a ton of knowledge and understanding of how a particular component works, and what you get in the end is a masterpiece. The devotion that goes into making every component of a Grand Seiko watch is astonishing.

The Grand Seiko case and bracelets are well-polished

In some instances, both Seiko watch models are made from stainless steel. The difference is that the Grand Seiko watch is made from a higher-quality stainless steel material. In other cases (such as in the creation of custom pieces) higher-quality materials – such as titanium and platinum- are used. Although stainless steel is the standard material used by almost every watchmaker to design cases, you can instantly tell there is a big difference in the quality of the material used on a Seiko and a Grand Seiko.

when you place the watches side by side. The Grand Seiko SBGA211 watch, for instance, has a high-intensity titanium case. It has a diameter of 41mm, a lug-to-lug distance of 49mm, and a thickness of 12.5mm. The back of the watch is made of a see-through, screw-back case with dual-curved sapphire glass and an anti-reflective coating on the inner surface.

This titanium case is highly polished to deliver a mirror-like finish and to create beautiful, sharply defined edges. For comparison, the Seiko SARY 147 has a diameter of 38.3mm, a lug-to-lug distance of 43.6mm, and a thickness of 11.2mm. It is a mechanical watch with a stainless steel case and a beautiful texture. The second timer is painted blue, unlike in the Grand Seiko watch where the blue color is heated into the second timer.

The movement of the timer on the Grand Seiko is also incredibly smooth, thanks to the spring drive technology. Seiko has a logo and elongated diamond markers polished to a mirror shine and mounted to a pale blue sunray dial. The date enclosure also gets a polished metal frame. The Grand Seiko’s markers are rectangular and they are polished to the hilt. The date marker also gets a polished metal frame. The logo is engraved on the surface of the dial and the words GS are well-polished and sit squarely above the engraved name.

Accuracy comparison between Grand Seiko and Seiko

The spring-drive technology in the Grand Seiko watches gave fair warning to the watchmaking industry that Seiko was here to stay. The company was constantly evolving. The spring drive movements have over 500 parts depending on the watch’s caliber and specifications. The combination of mechanical and quartz technology makes the spring-drive watch one of the most accurate watches in the world.

The Grand Seiko SBGA011 titanium-case watch that debuted in 2005 uses a 9R65 movement that has a plus/minus 1 second per day with a 72 hours power reserve. Continued modification and development have seen these watches record better results over time.

For instance, the SLGA001 (2020) Grand Seiko watch with 9RA5 movement has a 120 hours power reserve with an accuracy of plus/minus 0.5 seconds per day. The Seiko SARY147 watch has an average deviation of minus 15 seconds to plus 30 seconds per day. The movement is reliable and easy to service.

The snow-white face of the SBGA211G Grand Seiko watch

The SBGA211G is among the best diving watches from the Grand Seiko line. It has a bright white dial and polished clock hands. Unlike most watches, the white dial on the Grand Seiko watch is not painted. The brilliant color is made of a special silver plating process that creates snow white texture.

A long and complex process is involved in the creation of the stunning snowflake dial. After silver plating, machining, drilling, and printing the letters follow. The logo and indexes are set by hand by a highly skilled watchmaker.

Watch band types

You have unlimited options when it comes to watch band types for both Seiko watches. You can have both clasp and strap bands on your Seiko watches. The width of the wristband in SBGA211G Grand Seiko is 20mm thick and 193mm long. The clasp type is a three-fold clasp design with a push button release.
Seiko watches have 3 band choices; a metallic band, a silicone band, or a polyethylene band.

Although none of these bands gives you a luxurious feel, they are practical and can easily be replaced when they get damaged. The metallic band is a standard stainless steel band. It is not polished and it features a simple three-fold push-to-release button. The different band parts have not been treated to withstand rust.

Water resistance of the Seiko watches

The degree of water resistance of your Seiko watch is indicated by markings on the back of the case. A watch’s water resistance is not permanently guaranteed because it can be affected by factors such as deformation, age, and damaged parts. That said, Seiko watches still give an incredible performance underwater. Seiko SARY147, for instance, has a 5 bar (50m) water resistance rating. While diving, follow these instructions;

  • Ensure that you wear the watch within the water depth specified on the dial. If you dive deeper than the recommended depth, water may seep into the watch
  • Do not operate the buttons or the crown underwater as this may create spaces for water to seep into the watch
  • Avoid rocks or hard surfaces that may damage the watch underwater
  • After diving, rinse the watch with fresh water and then wipe it thoroughly dry. While rinsing the watch do not pour running water directly from a faucet. Rather soak the watch in a container and wash it clean before drying it.

You may notice that the rotating bezel of your Seiko diving watch becomes tougher to rotate while underwater. This is not a malfunction. It is the pressure of the water working against the watch’s movement. Most watches are not designed to withstand warm water, and Seiko watches are no exception. They may withstand an occasional shower but continued exposure will certainly damage them in the long run. And this applies to dive watches too. There is no such thing as a waterproof watch.

Other top features

To achieve a top-notch distortion-free design, Grand Seiko uses a concept called Zaratsu. This is a combination of the hairline and mirror-like finishes on the hardy titanium shell. This ensures that there are no distortions and light and shadow reflect evenly on the surface of this watch. The markers also undergo Zaratsu polishing which makes them crisp, distortion-free, and stunning to look at.

To emphasize the level of craftsmanship that goes into these watches, a Seiko watchmaker needs about 5 years of Zaratsu training before they can work on watch cases that will eventually be sold to the final customer. The indexes and hands are diamond-cut.

FAQ section

What do the numbers behind a Seiko watch stand for?

The numbers behind a Seiko watch are used to date the watch. You can tell when your watch was manufactured from the serial numbers you see on the back of your watch. The dating format is as follows;

The first number indicates the last digit of the year your watch was manufactured
The second number indicates the month the watch was manufactured
The last 4 numbers are special production numbers that are unique to every watch. You can use these numbers to get any production information about any watch.

Is Seiko better than Rolex?

Both Rolex and Seiko are great names in the watchmaking spectrum. It would be hard to narrow down and offer an opinion on which one is better because each watch is unique. Rolex is synonymous with luxury and you will find that the price point agrees. Seiko watches are more affordable, but this does not mean that they are inferior to Rolex watches in terms of craftsmanship.

It all boils down to your taste and how much you are willing to spend on a good masterpiece. Both brands have a great history that goes back to over a century. They pride themselves on creating excellent timepieces. Rolex is from a Swiss company while Grand Seiko is from a Japanese company.

What are the different Grand Seiko collections?

We have 3 unique Grand Seiko collections namely;

The heritage collection (such as the 44GS and 62GS watches)
The sport collection (such as the SLGA015 and SBGH293 watches)
The elegance collection (such as the SBGY013 and SBGW263 watches)

Do Grand Seikos hold value?

Yes, if the latest craze is anything to go by. They are excellent timepieces that offer a lot of value for the money. Other luxurious watches offering similar value command mind-boggling prices. Watch enthusiasts who appreciate the value of the Grand Seiko can vouch for the longevity of the company and the watches. The Grand Seikos can only get better with time.


Seiko and Grand Seiko watches are excellent pieces manufactured by highly skilled craftsmen. No matter what you choose between the two pieces accuracy and reliability are guaranteed. Seiko watches are valuable to people seeking a good timepiece on a budget. They will deliver as required and having paid a few hundred dollars for the watch, you would certainly get value for your money.

Grand Seikos on the other hand belongs to the caliber of people seeking a certain level of luxury and sophistication without breaking the bank. Sure, they are approximately 10 (or more) times more expensive than standard Seiko watches but they are way more affordable than other watches at their level (such as Rolex and Patek Phillipe).

The design of the Grand Seiko is meant to dazzle, and it does that perfectly. This is a watch you will enjoy wearing to whatever occasion you wish. The Grand Seiko is powered by a spring drive system, as opposed to the quartz system powering the Seiko watches. This is what makes the Grand Seiko truly the ‘Grand’ of the two watches. Irrespective of what you decide to go for, you will not be disappointed. However, if you are looking for a true classic and are willing to spend extra, the Grand Seiko is the watch to buy.

Seiko vs Tissot

For a long time, Swiss watches have been counted as one of the top watches on the planet that evoke luxury, quality, and an unmatched history of craftsmanship, but with Japan bringing on watches that have become synonymous with toughness and style, advice is often sought after by design enthusiasts who need help when choosing between top brands like Seiko and Tissot

Wondering about what is special about Tissot and Seiko that put them head to head in this battle of the watches? Notable inventions!! So for the many people trying to decide which to go for between the Seiko and Tissot, this comparison will offer you information that will give you a clearer view and make your decision process easy.

Is Seiko better or Tissot

Both Tissot and Seiko are brands that are celebrated for their precision and provision of decent quality watches over the years.

It is not surprising that both of them produce watches that are tough enough and essential enough to be considered first-line gear and the passion for pushing boundaries in both brands has distinguished them as top-tier watchmakers today.

Movements & Quality

From old-school mechanical calibers to GPS-enabled solar-powered quartz units, both brands come through hundreds of years of innovations and quality developments. Seiko, which started as far back in 1891 as Seikosha, was established eleven years after its founder, Kintaro began the repairs of watches and clocks in Tokyo.

It began producing its first watch for scuba divers in 1965 and manufactured one of the first quartz watches with a chronograph complication. Since then, new calibers have continually been introduced so that the brand has grown rapidly and has now become a selection of iconic Japanese timepieces with a reputation for consistently creating good movements so much that it was dubbed  “the forerunner of the quartz revolution” because it presented Earth’s first quartz watch in 1969, called the Seiko Quartz Astron.

A  piece that was three times more accurate than the mechanical watches of its time and could keep accurate time to within one minute per year! However, some people still prefer mechanical watch movements (which have some advantages over quartz), and since Seiko always puts desires first, it never abandoned its mechanical watch movements.

Its 7S line is an iconic example of Seiko’s mechanical workhorse wristwatches and they’ve always had excellent quality. From the well-praised  7S26, to the famed 4R36, all of Seiko’s mechanical watches use a traditional mainspring and share profound design ideas, even though they are all a bit different. 

Tissot watches on the other hand – in a bid to retain its status as a high-end watch brand – has always used materials of the highest quality and movements powered by ETA (ETA is Switzerland’s biggest and leading movement maker and brands like Omega, Longines and IWC use this movement) or Swissmatic movements (this one has a power reserve of 70 hours and guaranteed accuracy of about +/-10 seconds a day). 

Tissot introduced the first mass-produced pocket watch as well as the first pocket watch with two time zones as far back as 1853 and went further to present an anti-magnetic watch around 1930. Apart from Tissot watches being crafted under strict conditions that ensure quality, It has worked hard to build a legacy of offering excellent-quality watches that are water resistant to a depth of up to 200 meters

Style & Design

Next to outstanding quality and impressive history of craftsmanship, Swiss-made watches also come with an outstanding style and elegance. There’s a reason behind Swiss’s exclusivity. While both Seiko and Tissot produce exceptional timepieces praised for their designs and accuracy, Seiko has a strong focus on Haute Horlogerie, grand complications, and elegant dress watches.

Think of the legendary Seiko 5 SNXS73 and the oblong, timeless SWR053P1. There are also the noble complications of grand Seiko titanium watches that feature complex additional functions like flat surfaces polished to a mirror finish, minute repeaters, and perpetual calendars. The exclusivity of Seiko is directly tied to the fact that creating these highly crafted timepieces takes a whole lot of time.

Tissot, on the other hand, is much more renowned for its iconically-designed sports and gear watches – think of the Tissot Chrono XL, the Tissot PRC 200, Tissot Seastar, and Tissot Quickster (among others). Though Tissot produces dress watches as well, a lot of Tissot’s most popular models are iconic sports watches, loved by thousands of wrist watch enthusiasts for combining luxury alongside durable, accurate, and efficient components that are built to last beyond a lifetime without sacrificing functionality.

All of Tissot’s watches offer a stylistic versatility that Seiko doesn’t offer, but to match this Seiko presents finely created watches, with added innovations and movements found in more expensive watches among other brands. We can add at this point that Seiko has its own sports watches, like the Seiko 5 Sports.

But at the end of it all, Seiko is more focused on exquisite, complicated dress watches, and its range has always included some gorgeous ones and Haute Horlogerie pieces, such as the SARB065, SARB066, and Presage SSA343J1, whereas Tissot has a much sharper eye for high-end sports watches. So we see that the two brands have entirely different expertise, making it a bit difficult to say that one is better than the other.

Detection of Water Permeability

The water resistance of most contemporary watches from top brands is guaranteed so you should know that scratch and water resistance are features typically offered by both brands. Tissot has for a long time, utilized a touch-control sapphire technology, and produces highly functional timepieces with top-notch features that come without sacrificing a sleek design.

Both brands have watches that withstand up to 100 meters of water and some of Tissot’s diving watches are always tested in a pressurized tank in other to ensure water resistance. Seiko on the other hand offers watches that can be used for swimming and other everyday activities at 10 (20)-BAR.

Watch Case & Band

Tissot and Seiko always offer a wide array of watch band styles. From metal to leather styles, both brands continually combine materials to produce a strained, modern appearance. As far as closure styles go, Tissot watches come with ornate clape or the usual buckles. Nylon and rubber band watches (like Tissot T-Race T115417A) are also great options for some of the brand’s sports and field watches.

Seiko watches also presents watches with stainless steel bracelets, leather straps, and rubber and silicone bands. Fabric and nylon belts are also made widely available by Seiko so that you get the perfect fit for all your needs.

Popularity and Pricing

While neither Seiko nor Tissot openly releases distribution or production data, industry statistics estimate that in 2021 Tissot was exporting more than two million watches a year while Seiko was producing around 35,000 watches.

Tissot has been tied to sport to a great degree since the 1930s making it reputable and popular amongst athletes and other users across more than 150 countries according to World Tempus, it ranked number six in the top ten Swiss watch brands right after the Patek Phillipe.

In 2013, Swiss-made automatic watches made an unparalleled achievement by pairing down 51 parts (as against one hundred parts by other brands) to produce an entirely automated movement, and it combined all these parts with a single screw rapidly increasing its popularity and recognition.

Seiko on the other hand continues to be a recognizable brand popular for its simplicity of form and its understated elegance and productivity, such that in the first half of 2022, It launched 155 new models across its different product categories. One striking thing about Seiko and Tissot is their affordability. Seiko’s timepieces cost between $180 and $7,000.

While Tissot watches can be gotten for around $200 for the most affordable ones. Tissot’s sports watches even run somewhere between $200 and $3,000 and even though Seiko’s grand watches are more expensive, that doesn’t make them any better, and going from a Seiko to a Tissot watch should not be considered a downgrade. For a depth comparison, we are going to look at a more detailed analysis of watches within both brands.

Tissot Gentleman vs Seiko Presage

While many of our reviews are more on the higher-end side of the timepiece industry, we know that not all our readers and other watch enthusiasts can afford a Cartier or a Rolex which is why we are featuring modestly priced watches here that offer great value for money.

Recently, both Tissot and Seiko stepped up their game to a higher bar by upgrading their competition mechanically speaking, with upgraded automatic movements, adding finer details, and doing something more to create a timepiece that drastically challenges the watch industry every time.

Both watch brands offer their unique innovations and strengths and are dedicated to perfection. Now you may be wondering if you can pit them against one another, and pick the better of the two but we don’t think so. Here’s why.

Tissot Gentleman

Tissot Gentleman

If you are on the lookout for a perfect companion for everyday usage that can offer precision, reliability, robustness, versatility, and timelessness, ( so that your watch would not go out of style within a couple of years), then look no further because the Tissot Gentleman is an ideal multi-purpose watch that is both ergonomic and elegant for any circumstance.

It is suitable for wearing in business environments and can be worn where conventional dress codes apply. It is no news that Tissot has a long tradition of churning out reliable, and finely finished highly affordable watches. It is a part of the swatch group, and despite the affordability, these watches utilize superior industrial tools and are made under quality standards.

This automatic watch is made in such a way as to be powered by the energy of the person wearing it (the wrist’s movement enables the mechanism to run). Gentleman Powermatic 80 movement boasts up to 80 hours of power reserve, which is sufficient to keep on telling time accurately after three days of inactivity. This one was crafted to outperform its competition, whose movements generally provide less than two days of power reserve.

Seiko Presage

Seiko Presage

Presage not only combines a Japanese aesthetic sense with traditional craftsmanship but raises the essentials of watch production to the level of art. No doubt, Seiko’s mechanical watchmaking skills are top-notch and offer Japanese beauty, quality, and long-lasting performance in a package that is affordable, durable, and convenient.

True to its form, the Seiko Presage offers one of the most iconical mechanical GMTs on the watch world’s market in its elegantly detailed Presage family. Let’s take a quick look at just how they fare against each other on a closer level.

Best Seiko Sumo Watches

Seiko has a rich history in the development and manufacturing of world-class diver watches that are hugely popular and highly sought after by professionals and amateurs alike. To understand Sumo’s place in the pantheon of Seiko diver watches, I will provide a brief history and evolution of the diver watch.

1965- Seiko produces the very first Japanese self-winding diving watch that is water resistant to 150meters.

1968-Release of the 300-meter diver with a high beat self-winding automatic movement operating at 10 vibrations per second. By this time, Seiko has acquired twenty patents for the exterior of the diver watch alone.

1975– With the impetus of a letter that Seiko received from a professional diver, Seiko assembles a team to address the requests made in the letter. The diver explained that at depths greater than 300 meters, when using a diving capsule and saturation diving techniques, most watches sustained some degree of damage. This led to the creation of a diver watch made with a titanium case and water resistant to 600 meters.

1978– World’s first saturation diver watch with a quartz movement and water resistance to 600 meters.

1982– World’s first hybrid movement diver watch with alarm and chronograph functions and with a bilingual display. Water resistance of 150 meters.

1985– Improvement of the previous diver watch released in 1982, now water resistant to 200 meters.

1986– Development of a diver watch that is water resistant to 1000 meters. This is achieved through the use of a titanium case and a ceramic outside shell.

1990- The world’s first computerized diver watch is named the “Scuba Master.” This watch was equipped with a water and depth sensor and displayed both diving time and depth.

1992– Introduction of the world’s first kinetic diver watch. Power is derived by an automatic generating quartz movement. 200-meter water resistant.

1995– The creation of three distinct watches that are released during the year.

  • The “Diver Scuba” 200 meters. This timepiece calculates the depth of water and dive time. It also displays log data memory and air pressure.
  • 200-meter water resistant 24-hour hand kinetic “Scuba Master” with a titanium case and its battery does not need to be replaced.
  • The world’s first “Scuba Master” with an automatic calculating analog depth gauge and water resistance to 200 meters.

2000– Introduced a diving computer watch that displays the dive profile by recording the current depth of the dive and can also be used for nitrox diving.

2005– World’s first spring drive diver watch featuring a titanium case, 600-meter water resistance, and accurate to one second per day.

2007– The first Prospex Sumo watches are introduced.

The Seiko Sumo

The Seiko Sumo watch models are part of the Prospex collection of divers and sports watches. The Prospex name is a combination of the words professional and specifications and reflects the quality and design that are the earmark of the entire collection. These watches are inspired and manufactured in response to the requirements and desires of diving professionals worldwide.

They are surprisingly affordable given their quality and therefore are widely popular with both the diving community and those that enjoy larger case sporty timepieces. The Sumo collection is positioned as the middle tier of Seiko’s diver watch offerings, as reflected in its price.

The Sumo timepieces, as mentioned, are a subset of the Prospex divers watches and earned their nickname due to certain details reflected in the watch’s design. Some believe the Sumo name was given to the models because of the shape of the marker at the twelve o’clock position. The marker resembles an “oicho” which is the top knot worn by a sumo wrestler.

Others believe that the bezel reflects the shape of the “dohyo” which is the ring in which sumo wrestlers hold their bouts. Whatever the reason, the Sumo is one of the most popular and sought-after diver models in the Seiko collection.

The Sumo was first introduced in 2007 and quickly became popular for divers and sportsmen alike. The first three models were the SBDC001 in black, the SPDC003 in blue (also nicknamed “Blumo,” and the SBDC005 with an orange dial.

These initial models have been outfitted with an in-house manufactured 6R15 caliber mechanical automatic movement and as all Sumos water resistant to 200m. An additional earmark of a Sumo watch, and what makes it recognizable, is that the crown is at the four o’clock position.

The Sumo collection is also popular for its impeccable finishes and smooth lines which are uncommon for an otherwise large sports watch. The design team hit a home run in the marriage of the bracelet to the case and also the design of the case itself. The latest bracelet resembles the “oyster” style with a three-link pattern and again nicely finished lines. The watch has a very polished feel as you run your fingers over both the case and the bracelet.

Details of the latest generation of Sumo watches include the following:

  1. A 45 mm. Case with a measurement of 53 mm. From lug to lug.
  2. Stainless steel case (and bracelet) with a special hard coating to increase durability and appearance. 
  3. Unidirectional ceramic bezel allowing for 120 clicks per hour.
  4. Inhouse-produced 6R35 caliber mechanical automatic movement vibrating at 21,600 A/h and incorporating twenty-four jewels.
  5. Power reserve of 70 hours.
  6. Hacking function (Wearer can stop the second hand while adjusting the time, allowing for accuracy down to seconds}.
  7. Dial featuring large rhomboid markers and hands treated in lumibrite (luminous pigment).
  8. Sapphire crystal.
  9. 200-meter water resistance.
  10. Screw down stainless steel crown located at the four o’clock position.
  11. Three-year international warranty.

Seiko Sumo Chronograph

The Seiko Sumo Chronograph is a timepiece that celebrates the 140-year-plus existence of the Seiko watch corporation and all of its accomplishments in the area of timekeeping and time measuring. Four distinct events that contributed to the evolution of the present-day chronograph are the following:

  1. As the recognized official timekeeper of the 1964 Olympic Games, Seiko unveils the first Japanese watch that incorporates a stopwatch function.
  2. Seiko introduces the first automatic chronograph in 1969 that features a vertical clutch and column wheel.
  3. 1969 also sees Seiko manufacture the world’s first quartz watch movement which is a pivotal moment for the entire watchmaking industry and a revolutionary game-changer.
  4. With the advent of the quartz movement, sets the stage for the first solar-powered watch released in 1977 and the foundation for the present-day Sumo Chronograph.

The two models that are referred to as Sumo Chronographs, the SSC757 and SSC807 aren’t classic Sumo collection models but have been referred to as part of the collection due to the similar twelve o’clock marker as the regular Sumo models. The Sumo timepieces have manual automatic movements whereas these chronograph models are powered by the in-house V192 solar quartz movement produced exclusively by Seiko.

The Sumo Chronograph model SSC757

Details of the SSC757:

  • Stainless Steel case 44.5 mm. wide and 13.7 mm. thick.
  • Stainless steel screw-down crown, pushers, case back with a unidirectional bezel. Pushers are at the two o’clock and the four o’clock positions.
  • Sapphire crystal.
  • V192 caliber Seiko solar quartz movement (Remains charged for at least six months if charged by a direct light source).
  • Numberless dial with three subdials, one also showing the power reserve capacity of the charged movement. Each subdial has an independent motor and can be adjusted independently. Timing to 60 minutes in ⅕ second increments.
  • Numberless dial with Lumibrite hands, markers, bezel markings, and date display.
  • Date display between the four and five o’clock markers.
  • Water resistant to 200 meters.

The suggested retail price is $675.00

Details of the SSC807

The SSC807 is a 140th-anniversary limited edition watch that was introduced in March of 2021. This edition has all the components of the SSC757 but differs in the following:

  • Limited production of 4000 pieces.
  • Has a green dial
  • Comes with an additional silicone strap.

The Suggested retail price is $780.00

Seiko Prospex Sumo Green

This particular watch was created to celebrate the 50th anniversary of Seiko’s collection of divers watches and is available exclusively in Thailand. The Thai market is very important and strategic to Japanese manufacturing from both an expansionary aspect and in their worldwide marketing plans.

Every year some models are introduced only to the Thai community and make the country a treasure trove for watch collectors. The Sumo Green is one of these commemorative watches and is limited to 820 pieces. 

The watch has all of the characteristics and components of that generation of Sumo watches but has some unique aesthetic embellishments. At the heart of this timepiece is the Seiko in-house-produced 6R15 caliber automatic movement with a 50-hour power reserve.

The uniqueness of the anniversary model is found in the crafting of the dial. The green color lies upon a wave pattern that creates a three-dimensional effect. The green fades into a smoky gray towards the edges of the dial where it meets the bezel. There are also gold accents on the bezel and the crown and the sapphire crystal features a cyclops window magnifying the date. 50th is also reflected in gold below the hand pinion.

Seiko Sumo vs. Samurai

The Seiko King Samurai was originally manufactured from 2004-2008 and reintroduced in 2017. The watch got its nickname “King Samurai” because the hours and seconds hands supposedly resembled a Samurai sword.

The new model SRPE35K1 is outfitted with an in-house 4R35 caliber automatic movement with 23 jewels. The movement operates at 21,600 A/h and has a power reserve of 41 hours. The Stainless steel case is 44mm. and is completed with a sapphire crystal with a cyclops window over the date ceramic bezel, and a stainless steel bracelet. The watch is also water resistant to 200m.

In comparing the King Samurai with the similar Sumo model, I have chosen the SPD101. The features of the Sumo are listed in the Sumo description in this article. Where the two depart is in appearance and the feel on the wearer’s wrist. Though the Sumo is the larger of the two watches, the King Samurai can feel larger. 

The case and bracelet of the King Samurai are also different in that they are not as smoothly finished as the Sumo diver. The case and bracelet are blockier and edgier. The Sumo is smoother in appearance and feels very balanced on the wrist. The King Samurai also differs in the finish below the ceramic bezel. Instead of vertical grooves, it has a diamond etched surface as well as a milled stainless steel crown.

The crown is also at the three o’clock position as opposed to the four o’clock position on the Sumo watch. The one feature that does stand out on the King Samurai is the block-styled dial. It is attractive and really sets the watch apart in side-by-side comparisons.

Frequently Asked Questions

Is Seiko Sumo made in Japan?

The Seiko collection is manufactured and assembled in Japan. The watch may contain components manufactured in other Asian countries, but the watch is ultimately a product of Japan.

What is a Sumo watch?

As mentioned earlier in this article, Sumos became a nickname for the line of Prospex diver watches that had a particularly shaped twelve o’clock hour marker that resembled the top knot worn by a sumo wrestler. Technically the name refers to a subset of the Prospex collection of competitively priced high-quality diving timepieces.

These watches are manufactured to the specific requirements of professional divers using superior materials and the latest technology. They are also painstakingly fitted and finished and sit comfortably on the wearer’s wrist for their size and mass.

Why is Seiko Sumo popular?

The Seiko Sumo is popular for both its quality and reasonable price. There are many professional divers watches on the market that sells for much higher prices due to their brand names but offers similar features. There is a tremendous amount of value offered in the Sumo models.

Additionally, the Sumo offerings are quite diverse and there is a style for almost every taste. Attractive dial colors and color combinations contribute to their allure amongst sports enthusiasts.

What is Lumibrite?

Lumibrite is a luminous paint that absorbs light energy from either the sun or another light source, and stores it to be used and seen in the dark. The luminous properties do degrade over time.

Padi stands for the Professional Association of Diving Instructors. This is the world’s leading scuba diving training organization.

The Seiko “Padi” models are an excellent choice for divers who desire that added sense of certification to their diving instruments.

The Ice Diver gets its name from the colors that are reflected off of a glacier. The series sports a beautiful block pattern dial in either gray, green, or ice blue.

The answer to this question is a definite yes. If you refer back to the list of Sumo models earlier in this article you will see that there are four limited edition models featured. There are more and also several special edition models that are not limited in their production numbers.

Seiko is also renowned for releasing exclusive editions for particular markets that are not available worldwide. The Prospex Sumo Green mentioned in this article is an example of such an offering. These watches tend to retain and even increase in value due to their exclusivity and limited availability.

Is a Seiko Sumo a worthwhile purchase?

When compared to all of the professional grade diver watches in the marketplace, the Sumo is both an affordable watch and one whose purchase reflects great value.

What is the warranty on a Seiko Sumo?

The Seiko Sumo as well as most of the Seiko line are warranted for three years.


In conclusion, I hope I have provided ample information to encourage your interest in either purchasing your first Seiko Sumo diver watch or assistance in choosing your next Sumo for your collection. This article should encourage anyone looking to purchase a professional quality diver watch for either professional diving needs or merely for the weekend sportsman or diver. 

The diversity in dial colors and variety of limited editions offer a timepiece for almost every taste. The affordable pricing and superior construction of the Sumo collection should make these watches a consideration for anyone who loves the sea.

Despite the large case measurement, the Sumo sits surprisingly comfortably on even smaller wrists that otherwise would not carry a larger watch well. This is a testimony to the smooth finishes and seamless incorporation of all the materials used in the construction of the timepiece as well as the union of the case and bracelet.

140 years of watchmaking knowledge and success are evident in the Sumo models as well as over 50 years of diver watch expertise. In the history of the Seiko diver watch, there is little that the company has not addressed to answer the requests of the diving community. Thus the “Prospex” Professional specifications reputation.

Any diver can wear a Sumo with confidence and know they have a watch that is water resistant to 200 meters, is easily readable in the darkness of the ocean depth, and has a unidirectional bezel that is an essential tool for diving.

Though there are fifteen diverse styles of Sumo watches listed in this article, there are many more models to choose from. If you are looking for a diver watch or just an attractive sports watch that is durable and an eyecatcher, I suggest you visit a Seiko dealer and try on a Sumo for yourself.

Nothing speaks louder than experiencing the feel, quality, and look of these watches on your own wrist. I will confidently say that you will neither be disappointed nor regret the purchase of your new Sumo watch.
