Sinn U200

The Sinn U200 is a diver's watch from the manufacturer in Frankfurt am Main. This model impresses with technological refinements such as the case and crown made of highly robust and seawater-resistant submarine steel. The tegimented rotating bezel also ensures maximum robustness; it is scratch-resistant and guarantees increased functional and fogging safety thanks to the Ar-Dehumidifying technology. Although the exterior of the U200 initially suggests that it is a stainless steel watch, the trained eye quickly realises that it is made from something special. This watch is made from U-boat steel once developed by Thyssen-Krupps for the German Navy's submarine class 212.
