(S23635)Limited Edition of 1,200pcs
Since its birth as the first domestically produced diver's watch in 1965, Seiko's diver watch has been releasing epoch-making products equipped with its technology one after another. It has continued to evolve for over 50 years and has earned high praise and trust from professional divers and adventurers worldwide. Among them, the Quartz Divers, announced in 1986, is Seiko's first 1,000m saturated diving waterproof specification. For the first time in the world, ceramics are used as the material for the outer body protector, and the combination of a lightweight, highly corrosion-resistant titanium case and a one-piece structure without a back cover boasts high reliability.
The launch of the limited edition S23635 (SBBN051) commemorates the 35th anniversary of the Seiko Prospex Marine Master 1986 Professional Quartz Divers.
