U212 S E

This model is no longer available in our current range.
U212 S E

The U212 S E is the only model with a diameter of 47 mm, making it our biggest 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 seawaterresistant German submarine steel, which makes the watch suitable for saltwater diving. The U212 S E 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.
