Seiko Prospex Sea GMT Automatic With Manual Winding 42mm Watch

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.

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.

The new clasp can be adjusted in six steps, each measuring about 2.5mm, for a total range of approximately 15mm. It allows for a comfortable fit at all times, accommodating changes in wrist size during diving and daily life.
