Seiko 7002: A True Japanese Great. Review & Modern Alternatives

Seiko 7002 FI 1

Last updated June 2020

Since the late 1800’s, Seiko have been pushing the bar when it comes to timekeeping across the world. With the introduction of their first wristwatch in the 1920’s, Seiko vowed to create watches that were as stylish as their competitors, whilst being functionally rich and robust for the day to day wearer.

Short for the word “Seikosha”, roughly translated to “House of Exquisite Workmanship”, Seiko’s founder Kintaro Hattori set out to dispel the 20th century myth, that any products made in the eastern world could not stand up to the quality of a western rival.

Whilst in the modern watch community Seiko are known for their mid-range pieces, it is important to note that the brand have been at the cutting edge of watch making across the last three centuries. Through the 20th century, Seiko pioneered the first Quartz and Kinetic winding watches, but it’s their Diver range we’re interested in today and specifically the Seiko 7002.  

As underwater diving started to become popular in the 1960’s, Seiko stepped into the water resistant watch market with the Diver 150M model. Zoom forward to 1988, and the 7002 took it’s place as Seiko’s front running and now fourth generation watch for divers worldwide.

Seiko were set as the go-to brand for divers, but the 7002 has become a watch with appeal far wider than just the water sport fanatics. So let’s take a look at what makes the 7002 so popular, break down this iconic watch part and part and see how you can get your hands on one, or a modern alternative…

The Dial


The 7002 brings together style, simplicity and functionality to make it a truly legendary divers watch. It couples a matt black face with distinctive rectangular hour markers to maximise accurate timekeeping in underwater conditions. Both the hands and hour markers have a unique, green colouring given by the luminous finish to enable full sight in dark, underwater conditions.

The hands again have a unique Seiko styling, with the minute hand incorporating an arrow-shaped design. The 7002 differed from its predecessor, the 6309, by returning to a date only indicator at the 3 o’clock position, leaving behind the day/date indicators of the past.

The 7002 was in the Seiko range between 1988 and 1996. During that eight year reign, a number of different variants of the 7002 were released with slight differences between them. Whilst slight size difference are out there, the 7002 measures 41mm in width, 45mm in length and a 13mm thickness. Whilst not the smallest watch in the world, the 7002 combines a sturdy, stainless-steel makeup within a streamlined design to ensure it is an asset and not a hindrance to all wearers, divers and non-divers alike.

The Bezel

The bezel is a key element to any divers watch, allowing the wearer to accurately track the amount of time they have been underwater. The 60 click, bi-directional rotating bezel of the 7002, provides full 360 functionality to the wearer.

Across the many variations in the 7002 range, the stylings of the bezel commonly changed to suit the different tastes of the diving watch market. The classic bezel seen above, incorporated the same luminous style as the dial with ‘Pepsi’ style bezels (as seen in the image below) becoming a popular choice for later releases.


The Strap

For the watch purists among you, the original 7002 strap consisted of a black silicone-rubber offering which was stamped with Seiko Diver’s branding. It is extremely rare to find the original straps on a 7002, with replacement aftermarket straps commonly found due to the wear and tear a watch of this type and purpose encounters.

In some of the later 7002 releases, different strap styles and materials were released, again to appeal to different sections of the market. The use of stainless-steel Oyster and Jubilee straps were common, adding an extra robustness to the already bullet-proof 7002.  

The Stats

The legendary 7002 has a lot to it to ensure it’s the timepiece of choice for the diving community, let’s take a look at some of the stats:

– Water Resistant to 150m – 200m for Later Model
– Fully Automatic
Movement Frequency of 21,600 BHP
– 40 Hour Power Reserve

It’s a really broad range, so let’s pick out a few of our favourites!

Seiko Prospex Samurai

If you’re not a fan of the blue/red pepsi colourings and want to be a little closer to the original 7002 colours, the standard Prospex Samurai may be the one for you!

Specs wise, this one is incredibly similar to the pepsi model above, still boasting the 200m water resistance, luminous markings and date window.

Design colour aside, the major difference here is the lack of PADI partnership but this isn’t to say it’s not a fully certified, highly reliable dive watch!

In fact, this has been one of Seiko’s most popular watches in the last 5 years, bringing together the classic design, great functionality and handy additional features for diving such as a hacking movement and manual winding!

Other 7002 Alternatives

Aside from Seiko, there’s a number of different diving watch manufacturers on the market. And whilst all of them follow the same outline look and feel, they have their quirks to suit different tastes.

Let’s take a look at some standout performers!

Citizen Eco Drive Promaster Diver

First we come to Seiko’s old nemesis, Citizen. The Japanese brands are often put head to head given their similar styles, history and price points. The Promaster Diver is a great alternative to a Seiko 7002 or Prospex as you’ll see below!

With it’s 200m water resistance, rotating bezel, lume markings and date window, it’s nearly a carbon copy of the classic Seikos. The key difference with this watch, and indeed most Citizens, is the movement.

This one’s powered by Citizen’s Eco Drive solar movement, utilising natural light to keep the watch powered for months on end.

The Verdict

Seiko’s mid range offering, often leads to them being disregarded among the most popular watch brands in the world. Since 1880, Seiko have been revolutionising the watch market, with big strides forward made in Quartz and Kinetic technologies.

Now seen as true specialists in the diving watch market, Seiko have made a name for themselves in the sports market, with the classic 7002 the piece of choice for many. With it’s sturdy and robust makeup, luminous design style and functional bezel, the 7002 maintains it’s dominance nearly 30 years after its first release.

Unfortunately, they can be tough to find in good condition, so you may need to shoot for a modern alternative. The Prospex range is Seiko’s leading range now, with a number of options to help you get a 7002-inspired piece. Aside from Seiko, a number of brands such as Citizen, Orient & Casio offer great alternatives, so there’s plenty of choice to be had!
