The nickname Sumo was initially not the official name of this Prospex series of watches. Yet somehow the name stuck and is now acknowledged by Seiko itself. The name’s origins could be explained by some theories. The first theory is that of the robust, oversized countenance of the watch together with a thin 20mm bracelet. The second explanation lies in how the 12 o’clock marker looks like a Mawashi, the underwear donned by Japanese sumo wrestlers during a match.
