The diving watch U212 is a professional mission timer which uses genuine German Submarine Steel, a material with extreme seawater-resistance and the highest level of non-magnetic properties. In the movement itself, functional reliability between -45 °C and +80 °C is ensured by the SINN special oil 66-228. And that's not all: with the captive diver's bezel, this diving watch is well-equipped to measure the duration of a dive accurately.
Fogging of the dial poses a safety risk when diving. To prevent this, we use EDR seals. This material, with its extreme chemical resistance and only a quarter of the gas permeability of conventional seals, prevents moisture from diffusing into the diving watch. The scratch-resistance sapphire crystal glass withstands even the highest pressures. The case is equipped with the Ar-Dehumidifying Technology.
