In 1968, Seiko launched a revolutionary new innovation with the world’s first hi-beat Diver’s watch. With a case design inspired by the original 1968 piece, carrying the name ‘Marinemaster’ from Seiko’s heritage in diving watchmaking, this new limited edition re-interpretation has the same 300m water resistance.

Inspired by the mangrove forests of Okinawa which connect the sea and land, this special edition features a deep green dial to express the unique natural environment of these coastal ecosystems, accented with elegant rose gold-coloured details.

Designed for high contrast under water, all aspects are optimised for diving conditions: a streamlined case, with the crown in the comfy 4 o’clock position, Lumibrite for legibility at the darkest depths and a unidirectional rotating bezel as per ISO Diving standard. The bracelet features a three-fold clasp with push button release and slide adjuster.

Especially crafted for divers, the 8L45 Calibre is a highly accurate, reliable and robust movement. With an accuracy of +10/-5 seconds per day and a 72-hour power reserve, it combines high precision, reliability and durability.

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.
