"They call me Prospex" - Seiko Prospex's JARE Antarctic Expeditions

Seiko’s, and Japan’s, first diver’s watch was born in 1965. With water resistance to 150m and an automatic movement, it proved its high quality and reliability when worn by members of the 8th Japanese Antarctic Research Expedition in 1966. Thanks to the positive reaction of the members of the expedition on their return, Seiko’s diver’s watches were chosen by the same research team between the years 1966 and 1969, during which time the landmark Seiko diver’s watch with 300m water resistance and a 10-beat automatic movement was created, in 1968.
