This modern re-interpretation of the 1968 Diver's watch is inspired by Japan's 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 for sixty years has innovated in wearable, precise watches for professional and recreational divers.

This modern watch is powered by the new in-house Calibre 6R54 and is the first of Seiko's diving watches with mechanical GMT functionality. Built for wearability: the bracelet fits comfortably due to its low centre of gravity and short-pitch and durability: with a three-day power reserve and high-quality scratch resistant Japanese ceramic Diving scale, its water resistance is up to 200m.

Prospex is a combination of the words "Professional" and "Specifications", Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.

Seiko began as a clock repair store in Tokyo in 1881 with a purpose to pursue watchmaking excellence and has grown into a global timekeeping presence. Renowned for horological innovation, Seiko timepieces deliver precisely beautiful Japanese aesthetics, brought to life through in-house manufacture.
