U2 (EZM 5)
Ref.: 1020.01
The Sinn U2 (EZM 5) isn’t just a dive watch. It’s an overbuilt, no-compromise tool designed to handle extreme conditions. Its German submarine steel case is pressure-resistant to a ridiculous 2,000m, and the Ar-Dehumidifying tech ensures crystal-clear legibility no matter the climate. A second time zone adds practicality, while the left-side crown keeps things comfortable. Whether you’re deep underwater or just want a watch built tougher than you, the U2 is ready for action.
