SUMO- These watches are nicknamed by SEIKO fans as the ‘SUMO’ notable features in their design are the larger shaped bezel with is inset into a broader case. This look sits in contrast with the relatively narrow 20mm band. It is also said that the marker at 12o’clock loosely represents the ‘Mawashi’ the underwear worn by Japanese sumo wrestlers during a match. The sumo tends to be a heavy-duty watch and is ill-suited for someone with smaller wrists.
