U1 watches are certain to impress, since submarine steel has been used in the production process, adding to the resilience of the timepiece. This watch is equipped with ETA 2824-2 automatic movement that performs 28 800 vibrations per hour and has 25 bearing jewels. The movement is resistant to both shock and magnetic influences. The bezel is scratch-resistant because of the usage of Sinn’s Tegiment technology. Additional features include minute ratcheting on the bezel, a date window at the 3 o’clock mark, crown at the 4 o’clock mark, luminous hands and markers and scratch-resistant sapphire crystal glass with anti-reflective coating.
