Sinn U212 SE Diving Watch

The U212 SE with a diameter of 47 mm is the biggest Sinn diving watch to date. The interplay between the high quality Black Hard Coating and the ivory-coloured coating for indices, hands and numerals is truly striking. While the colouring is in a vintage style, the features of the U212 S E are absolutely state of the art.

For example, the case and crown are made of high strength sea water resistant German submarine steel, which makes the watch suitable for saltwater diving. The U212 SE also features a captive diver’s bezel and Ar-Dehumidifying Technology for greater functional reliability and freedom from fogging. 300 U212 S E watches are being produced, each with an engraved limited-edition number.
