Prospex Auto Divers SPB143J1

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.

Seiko Prospex watches are designed 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 watchmaking has changed global dive watch standards.
