SUMO: These watches are nicknamed by SEIKO fans as the ‘SUMO’. notable features in their design are the larger shaped bezel which 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.


BLUE FIRE CRATER: This Australasian limited edition is inspired by the blue fire crater of Indonesia. This watch features a deep blue toned dial that expresses the powerful and enigmatic energy of this extraordinary natural specticle. The dial also features silver toned, LumiBrite, luminescent hands and features as well as a date window, all protected by sapphire crystal glass. The case of the watch measures 45mm and is made from stainless-steel, it features a blue uni-directional rotating bezel and has its individual serial numbers engraved on the case back. This watch comes with a blue silicone band and now comes in a standard, SEIKO premium box.
