The Hydrotimer was designed to be an instant classic dive watch. Although it shares the same silhouette as the Strat-o-timer GMT, it's packed with its own unique features. The bezel is a uni-directional 120-click sapphire bezel with BGW9 Swiss Superluminova covering the entire surface. The navy dial features a matte finish and complemented with silver indices and hands. Powered by a regulated Miyota 9039 automatic movement, the Hydrotimer is robust as it is good looking featuring a scratch resistant coating up to 1200 HV. The Hydrotimer is truly designed to be the everyday watch.

Premium Design and Features

More Accurate

We regulate each movement in the USA to a standard of +/-5 seconds. It is important to us that every Hydrotimer is as precise as possible.

Less Scratches

A scratch-resistant coating protects the Hydrotimer from minor blemishes and increases the scratch-resistance by roughly 500%.

Assembled by Hand in the USA

Assembled and tested in America for extra quality control and an even better post-purchase experience.

Extra Secure Fit

A classic tropic strap with custom details to ensure a comfortable, secure fit on your wrist throughout the day.

The Perfect Size for All Wrists
