Dive Watches

Choosing between the Rosemariner and the Nautirose

The Rosemariner is the classic sports-diver shape: a 40mm case, a one-way rotating 60-minute bezel and a screw-down crown, powered by the Seiko NH35 automatic. Pick it if you want a true tool-watch look that works with a T-shirt or a suit.

The Nautirose is our integrated-bracelet sports watch. It shares the 100m rating and NH35 automatic movement (the Open Heart version uses the Seiko NH38, which shows the balance wheel through the dial), but trades the rotating bezel for a flatter, more angular case.

What 100m water resistance means in practice

Both models are rated to 100m (10 ATM). That covers swimming, snorkelling, holidays and everyday wear, as long as the crown is screwed fully down. They are dive-style watches, not ISO 6425 certified diving instruments, so we do not recommend them for scuba diving.

Rinse the watch in fresh water after the sea or a chlorinated pool, and never operate the crown while it is wet.

Using the dive bezel

The Rosemariner bezel only turns anticlockwise. Line the triangle up with the minute hand when you start, then read elapsed time where the minute hand points on the bezel. Because it cannot turn the other way, an accidental knock can only make the timed period look longer, never shorter.
