Early Access Seiko Prospex Clearwater Blue Marinemaster 1965 Reinterpretation Diver Watch Massive 45% Savings [kMmIaG5X]

Seiko Watch Prospex Clearwater Blue Marinemaster 1965 Reinterpretation Diver SJE099J1. This ice-blue ‘clearwater' design is inspired by both the first Japanese Diver’s watch launched in 1965, and the Seiko Marinemaster design from the 2000s.

The 1965 Diver’s marked the beginning of Seiko's journey with diving watches, and the never-ending commitment to designing durable timepieces. The original piece was deemed so reliable that it was gifted four times to Japanese Antarctic Research Expeditions and on extreme trips to the North and South poles, as well as Mount Everest. The Marinemaster was specifically designed for professional divers with its robust case and strong strap.

This latest piece features inspired elements from the 1965 original diver, including its silhouette and distinctive hour markers. The horizontal line patterned dial evokes a marine-sports style, whilst its sapphire exhibition case back is a first in a Seiko Diver. Its lugs have a mirrored finish for added light reflection, whilst its thick hour markers are Lumibrite-coated for high legibility. This is the slimmest of all Seiko mechanical divers watches at only 12.3mm, despite the box sapphire glass and the exhibition case back.

This piece is powered by the new slim calibre 6L37 movement which maintains strong accuracy of -10 to +15 seconds per day, with a power reserve of 45 hours. Importantly, the new Marinemaster meets Seiko's strict Diving ISO standard specification.

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.
