Product description

The design of this stunning GMT diving watch is a re-interpretation of the 1968 first hi-beat one-piece Diver’s watch created by Seiko. The success of the 1968 model laid the foundation for Seiko Diver’s watch development which today is still as innovative and high quality as it was then. The watch is powered Seiko’s own Calibre 6R54 movement and is the first of Seiko’s diving watches with mechanical GMT functionality. The bracelet fits comfortably due to its low centre of gravity and short-pitch. With a 72 hr power reserve, high-quality scratch resistant Japanese ceramic diving bezel and water resistance up to 200m, the watch looks fantastic, both in the water as on land.

This Seiko watch has a case made of Steel silver with a diameter of 42 mm and is fitted with a Metal strap. Inside the case lies a Seiko Instruments Inc. movement and the watch features a Sapphire crystal.

The watch is 20ATM. This means the watch is suitable for diving. The watch comes with 2 Year Warranty.
