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. Continuous enhancements over the decades in safety, reliability, legibility, and ease of use have made Seiko a leader in diver’s watches.
Seiko is introducing a new movement in the long-trusted 6R family that has a GMT function and a power reserve extended to a full 72 hours. Caliber 6R54 is presented in three new Prospex creations that are all modern re-interpretations of a Seiko classic from 1968 and are designed for diving with 200-meter water resistance.
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. Each new watch adds the GMT hand while incorporating 200 meters of water resistance, a highly legible Lumibrite-equipped dial, and a unidirectional bezel in scratch-resistant ceramic. And the automatic mechanical movement runs for three full days when fully wound.
While the watch’s design reflects its heritage, every aspect of this new creation is fully up to date in specification and execution. The case design is inherited from the 1968 original, and the case sides are mirror finished. The edge of the unidirectionally rotating bezel offers easy control.
The watch has a stainless steel case with super-hard coating and appears on a new three-link stainless steel bracelet that has a slim profile that allows it to sit securely and comfortably on the wrist.
