Sinn engineers crafted the U1 diving watch to offer exceptional durability and resistance against extreme environmental stressors. Constructed from the same high-grade, non-magnetic, and seawater-resistant steel used for the hulls of German Navy Class 212 submarines, the case features a captive, ratcheting bezel designed to withstand heavy impacts. Certified by DNV GL for pressure resistance up to 100 bar (1,000 meters), the watch is powered by a Sellita SW200-1 movement and is recognized for its unique hand design.
