SINN T1 B: Diving Watch, High-Strength Titanium Case with Matt-Blue Dial

The T1 B is a mission timer, all of the case parts are made from bead-blasted high-strength titanium, characterized by a matt-blue dial. Titanium has a particularly low weight, very high strength and exceptional resistance to saltwater, so it is perfectly designed for use in saltwater. The metal also offers a high degree of wearing comfort as it causes no allergies.

The watch comes in a 45mm diameter case and houses a ETA 2892-A2 self-winding movement.

A further special feature of the T1 B is the Captive Safety Diver’s Bezel which is distinguished by two basic components: its secure attachment and rotation protection. The set time is especially easy to read thanks to the different shapes of the hour and minute hands. To ensure that this is also possible in the dark or in adverse viewing conditions, the T1 B also features colour-differentiated luminous paint for the minute hand and key mark on the bezel for clear reading of set time.

The suitability as a diving watch for professional use was verified by the classification company DNV GL. DNV GL verifies and certifies pressure resistance to a diving depth of 1,000 metres, as well as temperature resistance and functionality, in accordance with the European diving device standards.
