Each of our 500 limited edition diving watches is uniquely numbered and boasts a light-reflecting dial that creates an exciting interplay of colour. This iridescent finish is the result of the shimmering black mother-of-pearl on the dial, which is a feature of this edition.

Combining mother-of-pearl with a diving watch seems only natural, given that they are united by the element water. What’s more, mother-of-pearl is a naturally occurring product, making each dial unique. The overall design is completed by the Black Hard Coating, which highlights the striking form of the U50 S Mother-of-pearl S and its minimalist display.

The timepiece is also equipped with special technical features. For example, the case and crown are made of high-strength German Submarine Steel. The classification company 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.
