In 1965, Seiko created Japan’s first diver’s watch, a groundbreaking timepiece that set a new global benchmark for underwater instruments. This new Prospex Diver’s 300m continues that pioneering legacy while also contributing to marine conservation.

Seiko Prospex supports the future of marine life through its Save the Ocean initiative – a mission to help protect the world’s oceans now and for future generations, and to secure this legacy for divers everywhere.

The vivid ‘tranquil teal’ blue dial evokes the sea, with LumiBrite on the hands and indices ensuring clarity in the darkest depths. Its 40mm case features a super-hard coating for durability and a unidirectional rotating bezel designed for safe diving use.

At its heart lies the in-house 6R55 automatic calibre, delivering a 72-hour power reserve and accuracy of -15/+25 seconds per day. Water resistant to 300m, it is built for professional diving environments.

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.
