The SPB103j1 was released in 2019 and is the successor of the previous model SBDC031 which it replaced. If you require an extra large bracelet or you are in need of additional links these may be supplied at an additional cost. 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.

The watch is presented with the now-iconic ”Sumo” case which is, as mentioned, large, bulky, and sturdy.The Seiko SPB101J1 (SBDC083 ), also known as the Seiko Sumo, is perhaps one of the greatest entry-level sports watches and one of the better built-in Seikos line-up for the money. In 2019 Seiko finally updated their Sumo models giving them a slightly different and refined look, but perhaps most important an in-house improved movement Caliber 6R35.

The new Seiko Sumo – or Prospex Diver 200m SPB103J1 – isn’t a complete departure from the older model and keeps most of the attributes found on the SBDC031. Consider this new version as an update, with multiple improvements and slight visual evolutions, rather than an entirely new watch. All in all, the fundamentals are still present but the technical side has been improved, for a better owner experience. 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 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.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. We understand the importance of sizing the length of your watch bracelet or strap to provide the perfect fit.
