Seiko Prospex Marinemaster 1968 Heritage Diver’s Watch

Seiko’s journey in diver’s watchmaking began in 1965 with Japan’s first diver’s watch, which accompanied members of the Japanese Antarctic Research Expedition to the South Pole from 1966 to 1969. This model was followed by the creation of the nation’s first 300m water-resistant diver’s watch in 1968. In the decades since, Seiko has developed new technologies, designs, and features that have made its diver’s watches a trusted favorite among professionals and enthusiasts worldwide.
