SPB385J1 Prospex ‘Glacier blue’ GMT LIMITED EDITION

This limited-edition, modern re-interpretation of the 1968 Diver’s watch is inspired by both Japan’s first hi-beat one-piece Diver’s watch created by Seiko as well as commemorating the 110th anniversary of Japan’s first wristwatch, as created by Seiko.

The success of the 1968 Diver’s 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.

This design of this watch is inspired by the ice of Antarctica, expressing the accumulation of time – linking the Antarctic history of Seiko diver’s watches with the time it takes for a glacier to form into its beautiful structure. Its three-dimensional dial pattern and colour feature over 2,000 surfaces and have been designed to express the natural formations and pressure the glacier underwent during its long cooling period.

The watch comes with both a bracelet and fabric NATO strap option – with the fabric strap being made 100% of recycled bottles.

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.
