U50 is a dive watch by Sinn.
This model was launched in 2025.
Equipped with an automatic movement from Sellita. The Hydro models are necessarily quartz watches, because the balance wheel oscillation of a mechanical watch could not overcome the high damping resistance of a liquid medium.
A key feature of these models is their excellent readability.
The case and crown are made of high-strength, seawater-resistant German submarine steel. Their underwater suitability has been tested and certified by an independent institute.
