The T1 is Sinn's mission timer; all of the case parts are made from high-strength titanium, bead-blasted. Titanium is distinguished by its exceptionally low weight, extreme strength and superior resistance to seawater. It also offers a high degree of wearing comfort as it causes no allergies.
A further special feature of the T1 is the Captive Safety Diver's Bezel which is distinguished by two basic components: its secure attachment and rotation protection.
The arrow-shaped minute hand is being used here for the first time in any of Sinn's watches. 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 also features colour-differentiated luminous paint for the minute hand and key mark on the bezel for clear reading of set time.
