In 2019, under the new references SPB101J1 and SPB103J1, the Sumo was slightly revised. The overall design was maintained, with only minor alterations. The bezel insert was redesigned with a more discreet scale, a new green dial/bezel model was launched. What really changed was the use of a sapphire crystal and the new calibre 6R35, with a beefed-up power reserve. The 2022 Seiko Sumo

Today, we sat down to take a look at the new Seiko Sumo Prospex Diver at Baselworld 2019: an update to a fan favorite. If you are looking for a professional dive watch that can do all of that, and have a seriously sporty presence on the wrist, the SPB103j1 ”Sumo” may just be the watch for you. As I was expecting, being a Seiko long-time lover, the overall quality of this piece is outstanding. The quality-to-price ratio is pretty high and it seems like this Seiko belongs to an upper category.The watch is presented with the now-iconic ”Sumo” case which is, as mentioned, large, bulky, and sturdy. Some other updates are here for the Seiko Sumo Prospex Diver and that includes a sapphire crystal – something that Seiko seems to be phasing in for divers above the Turtle level. Plus, and maybe this will serve as controversial, the Sumo contains a bezel with conservative font for its numbers instead of the wide, stretched numerals used in versions such as the current SBDC031. To my eyes, the indices change slightly too. They appear smaller and the 12:00 marker looks a lot classier. Regarding the hands, the minutes hand is thinner and the hour hand loses its chevron and gains a bisecting line through part of the lumed surface.

It is today one of the largest watch manufacturers today if we look at production numbers, and its great popularity has led to the brand releasing countless models in terms of design, purpose, and also price. Seiko’s watches range in price from less than 100 USD up to the thousands. Paying more than a thousand dollars, or even more than five hundred dollars for a Seiko is not something everyone is willing to do, but if we look at some of these watches in detail, it becomes very evident that you really get a lot in return. And in many cases, they still prove to be great value for money.If you require an extra large bracelet or you are in need of additional links these may be supplied at an additional cost. The Prospex in the name stands for ”Professional specifications” and simply means that the watch is built according to the needs and wants of professionals. These watches are made to handle seriously harsh conditions, including those that professionals subject them too. The good news is that if you want to change to a different strap or bracelet, you can easily do so thanks to the drilled lugs which makes changing the bracelet a breeze. Watch sizing can only be generally carried out on watches with metal bracelets, steel, titanium, gold, etc. The only downside for me is the pins and collars system for the bracelet links. I fitted the bracelet myself for my wrist and it was quite a battle.

Lastly, the Orient Kamasu (RA-AA0004E19A) is another comparable watch to the Seiko Prospex Sumo. It features a similar design with a stainless steel case and a reliable automatic movement. However, the Kamasu has a slightly smaller case size and a more affordable price point, making it a great option for those on a budget. Yes, the Seiko Prospex Sumo SPB101J1 is water-resistant up to 200 meters. This makes it suitable for swimming and diving. Looking at the case and the overall design, these updated Sumo SPB321J1 and SPB323J1 are typical no-surprise models. It’s all about improving the quality, not the style. As such, the oversized dimensions of the original Sumo are maintained. No downsizing policy here, the Sumo was and still is a large watch with a 45mm diameter, a 12.9mm height and an unmistakable lug-to-lug measurement of over 52mm. Reading this will certainly stop more than one potential customer, however, keep in mind that despite what the specification sheet indicated, the Sumo has always been more comfortable on the wrist than you’ll ever imagine. But don’t expect the comfort of one of the new compact Prospex. The Sumo SPB321J1 here worn on our editor Robin’s 19cm wrist.

The SeikoSPB101J1 has a sporty and robuststainless steel 3-piece-bracelet with a width of 20mm with brushed links and polished accents. The bracelet also has a wet-suit extension that offers a large enough extension to be used for putting the watch over your wetsuit. The bracelet really gives the overall impression of the Sumo a seamless look and feel. On the wrist, it gives the impression that it will never let you down. Bezel The Seiko Prospex Diver 200m SBDC031 was launched in 2007, as a mid-range offer, above the entry-level Turtle and Samurai and below the MarineMaster 300m. A better movement than the two affordable pieces on one side, a case with more attention to details too, but a lower water-resistance and no sapphire crystal like the MM300. The Seiko “Sumo” Diver 200m SBDC031, as is was between 2007 until 2018. I bought the Seiko Prospex Automatic Sumo SPB101J1 about ten days ago and I have been wearing it daily since then with great satisfaction. The SPB103j1 was released in 2019 and is the successor of the previous model SBDC031 which it replaced.
