A Pleasant Continuity - Custom fitted Seiko SUMO End-Plus

Endlink-Plus and SUMO are the perfect combination to enrich the space between Sumo and watch band.

One of Seiko's most popular divers watch ever produced was the Seiko Prospex 200M Automatic Seiko Sumo Ref. SBDC001, which was released back in 2007.

More noticeable traits all Seiko Sumo watches sharing are the fat markers used on the bezel. For those who didn't know where the nick name "Sumo", came from, many have said it was because the marker at 12’o clock resembles the ‘Mawashi’, which is the underwear worn by Japanese sumo wrestlers during a match.

Honestly, when I first looked at the 12 o'clock marker on the Sumo SBDC001, I was thinking it looked more like an onigiri, "Japanese rice ball", instead of a sumo wrestlers underwear.

If there's anything I had to say about what I don't like about the Sumo models is perhaps the spring bars are ridiculously far from the case.

I am 100% certain that I am not the only one who thinks that.   Its fine if you're wearing it with the original watchband, or perhaps with one of our custom fitted Sumo watch bands, then there's nothing to worry about.

However, the gap is much more noticeable if you are using a straight end canvas or perhaps a straight end rubber strap.

To rectify the problem with the huge gap space for the Sumo, we would like to introduce an end link add on for the Sumo when pairing with the Canvas & Chaffle FKM watch bands.
