U1 S Mother-of-pearl S

Without question, it is the shimmering mother-of-pearl on the U1 S Mother-of-Pearl S – limited to 300 pieces – that makes the dial and the entire watch so striking, in part because this natural product goes so well with the high-quality Black Hard Coating. The result of this successful collaboration is a timepiece with a unique, technical appeal that is a joy to wear each and every day. 

In addition to its striking design and minimalist display, the U1 S Mother-of-Pearl S is a high-quality timepiece that is also very suitable for everyday use. For example, the case and crown are made from high-strength seawater-resistant German Submarine Steel. Experts will recognise immediately that this timepiece is not only extremely resistant to seawater, but is also highly non-magnetic. The diver’s bezel with minute ratcheting has a captive connection to the case, so impacts are absorbed with ease, making it exceptionally durable. The positioning of the crown at 4 o’clock prevents pressure on the back of the hand, even during physically exerting activities.

By meticulously testing the U1 S Mother-of-Pearl S, DNV demonstrated its outstanding reliability for all to see. Pressure resistance was verified and certified to a diving depth of 1,000 metres (= 100 bar), as was temperature resistance functionality in accordance with the European diving equipment standards.
