Seiko Prospex Diver’s Watch in Tide Grey

This piece is a re-interpretation of Japan’s – and Seiko’s – first ever Diver’s watch, released in 1965. This design is a special edition commemorating 100 years of Seiko featuring on a watch dial – the brand name now synonymous with watchmaking innovation.

The original automatic 1965 Diver’s watch marked the beginning of Seiko’s watchmaking pursuit for diving reliability, safety, and professional specifications. From 1966-1969, this watch was worn by members of the Japanese Antarctic Research Expedition on trips to the South Pole, proving its durability in challenging environments.

The in-house built 6R55 automatic movement is accurate to -15/+25 seconds per day with a 72-hour power reserve and 300m water resistance.

This special edition piece is accompanied by an eco-friendly fabric strap, made of 100% recycled plastic 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.
