Seiko Prospex Sea 1968 Heritage Diver's GMT SS 42 MM Black Dial Watch HBC002J1

The 1968 Heritage Diver's GMT Watch is powered by the Caliber 6R54, which features a GMT function that allows it to display the time in two different time zones. The watch’s specifications have been enhanced to offer 300-meter water resistance.

A premium sports watch that combines practicality and durability

While the watch’s design reflects its heritage, every aspect of this new creation is fully up to date in specification and execution. The case design is inherited from the 1968 original, and the case sides are mirror finished. The edge of the unidirectionally rotating bezel offers easy control.
