About this deal

The Seiko Prospex Sumo SPB101J1 has a power reserve of approximately 70 hours. This means that it can run for up to 70 hours after being fully wound.

The dial of the Seiko SPB101J1 is slightly matte which gives it a textured and rich finish and also prevents glare and distracting reflections. The dial has not changed very much from the predecessor as the text is the same, the date window still has the white squared line around it and the Prospex logo still is present. The dial is however richly filled with luminova, or as Seiko calls it “LumiBrite”, which really does glow brightly in the dark. The SPB103j1 was released in 2019 and is the successor of the previous model SBDC031 which it replaced. Since 2007, the Sumo watches used the 6R15, and whilst this proved to be a trusted, sturdy, and reliable workhorse movement, Seiko decided it was time for an upgrade for this watch and therefore, it is powered by the latest version, the 6R35. This movement is still the same base but has been improved and refined. The dial is definitely the highlight of this watch as it has a lovely vibrant green color with a beautiful sunburst brushed finish. Due to the sunburst effect of the dial, it reflects the sunlight beautifully, and changes look from a fir green to a striking bright emerald color.At its very edge, closest to the crystal, it is sloped. This means the bezel sits taller than the actual crystal, which keeps it protected and minimizes the risk of getting scratches on it. Speaking of the crystal, this watch is equipped with a sapphire crystal. This is something that the predecessor did not have. A big improvement indeed. 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 When purchasing a watch which has a metal bracelet with adjustable links, we will gladly adjust the watch bracelet to fit your wrist before sending the watch to you - free of charge! The watch is presented on a three-link satin-brushed bracelet with polished edges on the middle links. The bracelet has a diver’s extension and safety clasp.

I bought the Seiko Prospex Automatic Sumo SPB101J1 about ten days ago and I have been wearing it daily since then with great satisfaction. We are also able to offer an exchange to a different product if required, please specify this when returning your product. Another comparable watch is the Citizen Promaster Diver (BN0151-09L). This watch also boasts a water resistance of up to 200 meters and a reliable automatic movement. However, the Promaster Diver has a more modern design with a larger case and a more colorful dial. It also features a solar-powered movement, making it a more eco-friendly option.Seiko – the brand that has become synonymous with affordable and qualitative affordable timepieces.In fact, we would even dare to say that Seiko’s watches are some of the best value money can buy if you factor in finish, quality, and durability. Yes, the Seiko Prospex Sumo SPB101J1 is water-resistant up to 200 meters. This makes it suitable for swimming and diving. This is generally a very simple procedure. We can do this for you, or you can get the watch adjusted locally. Option 1. Specify your wrist measurement and we will adjust it before being sent The movement is very precise and so far it gained about +2 seconds per day with a regular use. The 70-hour power reserve is excellent as it allows you to give the watch some rest over the weekend and to have it ready on Mondays (but, honestly, this is not going to happen to me as I’m pretty sure I will be wearing this beauty all the time I can). Sitting down to take a look at all the new models within the Seiko portfolio takes some serious concentration. The number of introductions can be hard to keep up with and there’s a lot of detail to remember. When we sit down, we go through Grand Seiko, all of the re-editions, the special editions, the limited models, the models supporting some sort of organization, and it truly goes on. Trust us, we love it that Seiko brings so much to Baselworld each and every year, but sometimes we crave some good, honest pieces without a story. Today’s introduction is such an example in the new Seiko Sumo Prospex Diver.

The bracelet is very beautifully finished and feels solid. Generally, affordable watches tend to compromise on the bracelet the most and have things like folded links and hollow end links which results in the impression of poor finish, but with this bracelet, Seiko shows that you actually get your money’s worth.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. Leather strap watches tend to fit without a problem for most wearers. However, watches fitted with metal bracelets often need adjusting to get the perfect fit. The Seiko Prospex Sumo is powered by Seiko’s 6R35 automatic movement, which provides a power reserve of up to 70 hours. The movement is accurate and reliable, and has been tested to meet Seiko’s high standards for precision and durability.

The watch is equipped with a sapphire crystal, making it extremely durable in rough conditions, and with a water resistance of 200M, you won’t have to worry about using your watch in water. Although the water resistance is told to be 200M, Seiko always tests their watches to see if they can handle more pressure than they are made for, which is done by always testing 25% more than what is specified. With that said, inofficially the case is 250M water-resistant. The lugs are 20mm, which is one of the most common sizes for watch straps, and with the drilled holes on the side, it is easy to remove and change straps and bracelets on it.The drilled lugs also contribute to giving the watch a more tool-like appearance which really enriches the tool-like look. This is a serious dive watch, so naturally, it has a good water-resistance. The Sumo SPB103j1 has a water-resistance of 200m/660 feet which makes it suitable for swimming, diving, and essentially any type of water activity.When it comes to comparable watches to the Seiko Prospex Sumo (Reference: SPB101J1), there are a few options worth considering. One such watch is the Seiko Prospex Turtle (SRP777). Like the Sumo, the Turtle is a dive watch with a similar design and build quality. It also features a reliable automatic movement and a durable stainless steel case. However, the Turtle is slightly smaller than the Sumo, making it a better option for those with smaller wrists. What is particularly interesting about this design is that its design has remained more or less unchanged since it was first presented, which goes to show it is a truly timeless design. Something watch enthusiast love, and proof that Seiko has done a great job with the design. The watch has applied hour markers with polished metal frames and applied Lumibrite. The minutes and hour hands are sword-shaped and are quite wide. The movement is perhaps the biggest difference going from Seiko’s 14-year-old 6R15 to the new in-house caliber 6R35. The movement is automatic with a central rotor and offers a power reserve of 70 hours, which is a huge improvement of 20 hours from the 6R15. This robust and durable movement gives makes this SeikoSPB101J1 a greatwatch in this price class. The movement beats at a 3Hz frequency making 21.600 beats per hour. 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.
