Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence with recreations and reinterpretations of landmark achievements.

This reference SPB183 continues a celebration of the 55th Anniversary of Seiko's first diver's watch with a reimagining of the famed 1970 model, complete with the iconic case design that revolutionized underwater safety with a recessed crown creating a built-in crown guard at 4 o'clock.

The rich marine blue dial features a date calendar and LumiBrite hands and markers.
