The New Seiko Sumo Diver.

The Seiko Sumo Prospex Diver is a watch that gained the nickname Sumo, from having such a chubby case size as it relates to its 20 millimmeter lug width. The Sumo is a big favorite among Seiko lovers, and the nickname is super cool for those who admire all things Japanese. It was back in year 2015 that the firm celebrated the 62MAS 50th anniversary with a relaease of an updated Sumo, and now would be a good time to look at this Sumo Diver watch once again. The watch has a high look, and is very durable, but at the end of the article, you will also be impressed with its very attainable price tag.

Seiko offers some very nice updates to this new Sumo watch. One thing is there was a new movement chosen for this watch. It is the 6R35 automatic movement that Seiko unleashed during 2018 in its Presage line of watches. In the last few years Seiko had been using its 6R15 movement in its dive watches, but that took the price over the $1,300 mark, and was not able to capture the size of audience that Seiko wishes to reach. So not only does the 6R35 movement offer less cost, it is actually a bit higher in accuracy than previous movements.

This new movement is only 3.7 millimeters thick, and so its more comfortable on the wrist. So regarding the case, it has a diameter of 45 millimeters, a thickness of 13.5 millimeters, and is 52.5 millimeters long. Excellent vision on that 45 millimeter face, and great legibility under water. The crystal is done in scratch resistant sapphire, and offers great clarity. The use of sapphire is an update that Seiko is using for its dive watches that are above the Turtle level.

I do wish however that the font on the bezel was larger than it is. I think the watch would be a bit more legible under water had the wider, stretched numerals been used. As for the hands, the minute hand is thinner than on earlier models, and the hour hand has lost its chevron, but has a line running trough the lumed surface. This watch is coming in at a price of $962. I think its awesome that Seiko managed to keep this watch in the 3 digit zone. This is one hell of a watch for the price, with a crazy long power reserve, and the coolest nickname in Tokyo. So check it out online, and go to Seiko’s website. Take a tour. Its a very cool website for watch lovers, and has plenty to offer you.
