Description

Ever since its first diver’s watch in 1965, Seiko has developed new technologies, features, and designs that have made the Seiko Prospex diver’s watch collection a favorite among professional and recreational divers the world over. Through more than a half-century of innovation, Seiko has continuously pushed back the boundaries of where sports watches, and diver’s watches in particular, can go and how they can be used. Today, Seiko introduces Caliber 6R54, a new movement in the long-trusted 6R family with a GMT function and power reserve extended to 72 hours. This is Seiko’s first-ever use of a mechanical GMT movement in a Prospex diver’s watch.

The GMT hand can be set independently in one-hour increments without interrupting the time-of-day hands and allows the wearer to see, at a glance, the time in a second time zone. The watch is water resistant to 200 meters, has Lumibrite on the hands and all 12 markers, and features a unidirectional bezel with a ceramic insert and a luminous pip. The watch is presented on a new three-link stainless steel bracelet with a slim profile that allows it to sit securely and comfortably on the wrist.

The watch’s design is a modern re-interpretation of the classic 1968 diver’s watch, Seiko’s first diver’s watch with 300m water resistance and a 10-beat automatic movement that was used successfully by the first person from Japan to climb Mt. Everest.
