Description

Built for Explorers
We have been building the Marinemaster since 1954, making it one of the oldest diver’s watches. This watch combines state-of-the-art technology with a robust design to stand by your side in any situation.

Solid as a Rock.
The Marinemaster M-40 in Rockstone Gray is built for the bold. Its understated design hides the powerhouse within – 300m water resistance and the UW-30 Performance Movement, ready for any adventure.

Engraved for Purpose.
With ultra engraving on recycled stainless steel, the Marinemaster M-40’s caseback invites you to reflect on life’s essentials. Engineered to perform, it’s both a robust tool and a timeless reminder.
