A premium diver’s GMT watch inspired by a marine-sport lifestyle.

A refreshing combination of blue and white

Inspired by a lifestyle steeped in marine sports, the watch has a blue ceramic bezel and silvery white dial to create a fresh and clean appearance.

Endowed with updated functionality

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 new clasp designed for comfort and operability

The new clasp can be adjusted in six steps, each measuring about 2.5mm, for a total range of approximately 15mm. This marks the first time that this clasp has been adopted in a non-limited-edition model. It allows for a comfortable fit at all times, accommodating changes in wrist size during diving and daily life.
