SINN U50 S Mother-of-Pearl S Limited Edition

German watch brand SINN presents a new self-winding dive watch made of German Submarine Steel with a mother-of-pearl dial.

Limited 500 pieces, this new professional diving timepiece 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.

It features a 41mm diameter case. 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 SINN U50 S Mother-of-pearl S watch houses a SW300-1 self-winding movement.

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.
