The Rotary Seamatic dive watch is enviably high-spec: it features a stainless steel casing and 3 link bracelet secured by a Divers Z clasp for optimal on-wrist security. The deep green dial, which displays luminous indices and open hour/minute hands, is protected beneath sapphire glass with a Cyclops date-window feature. This timepiece also features a black ceramic unidirectional bezel for the best possible underwater timekeeping. On the side of the 42mm case is a screw-down crown, kept secure from rough bangs thanks to a crown guard. Powered by the reliable Miyota 8215 movement, the watch is water resistant to 300m.
