Seiko Prospex Marinemaster 1968 GMT wristwatch, steel, HBC002J1
Stainless steel Seiko Prospex Marinemaster GMT watch with black dial and 300 m water resistance
The GMT function sets this Seiko Prospex Marinemaster dive watch apart from an ordinary diver's watch: you can keep track of two time zones at once. The black dial has a 24-hour scale and a yellow GMT hand, and the round case is stainless steel. The design is based on Seiko's 1968 diver's watch. Prospex is Seiko's collection of sports and dive watches, and its roots go back to the first Japanese dive watch from 1965.
The automatic Caliber 6R54 movement runs for about 72 hours, so the watch keeps time over a weekend. Water resistance is 300 m / 30 atm, and the Diver's marking means the watch is also suitable for scuba diving. The hands, indexes and bezel are luminous with LumiBrite. The inner surface of the sapphire crystal is anti-reflective. The case is 42 mm wide and 13.3 mm thick, and the strap is a 20 mm wide steel bracelet.
