SEIKO PROSPEX 1965 / 1968 / 1970 Heritage Diver's Watch
Save the Ocean Special Editions

1965 Original model

The 1965 diver's watch incorporated an automatic mechanical calibre and delivered 150m water resistance. The watch was designed for maximum reliability and legibility in the harshest conditions. It proved its reliability when used in the Antarctic during the 60s and laid the path to the development of future landmark watches.

1968 Original model

The landmark 1968 diver's was Seiko's first watch with 300m water resistance and a 10-beat automatic movement. With a one-piece structure, a mono-directional rotating bezel and screw-down protection crown, this timepiece pushed back the frontiers of precision, durability and ease of use in watches for professional and recreational divers.

1970 Original model

In 1970, Seiko introduced a diver's watch whose asymmetrical extension protected the crown at the four o'clock position. Its solid construction, luminous hands and indexes and 150 metre water resistance were perfect for those who required a timepiece with exceptional strength and visibility. The watch proved its reliability in extreme conditions when it was worn by the Japanese adventurer, Naomi Uemura, in the years 1974 to 1976 when he completed a 12,000km solo dog-sled run from Greenland to Alaska.
