The U50 delivers Sinn’s renowned durability and legibility in a 41 mm case diameter, designed for slimmer wrist sizes. 

​

The result provides a robust, scratch-resistant, edge to give added protection for the case. These features ensure the U50 is perfectly suited to diving use – a fact that has been verified by the classification company DNV GL (international registrar and classification society for professional diving equipment). DNV GL verifies and certifies pressure resistance to a diving depth of 500 metres (= 50 bar) and temperature resistance and functionality in accordance with the European diving equipment standards.

​

For those who love the functionality and look of the U1 collection but feel the size is too big, the U50 offers an attractive and viable alternative.
