Seiko Prospex challenges every limit, with a collection of timepieces for sports lovers and adventure seekers whether in the water, in the sky or on land. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative technology has changed global standards. We are constantly striving to bring ever greater reliability and safety to both professional and recreational divers.

This specific design is inspired by the 1965 Diver’s watch – the first 150m Diving watch in Japan.

Upgraded from the original for increased comfort and higher visibility, it has a clear dial layout, a smaller case size, lower centre of gravity and 70 hours power reserve.
