Visually, the diver’s watch is noticeable for the striking design of its matte-black dial and a display that concentrates on the essentials. The case and crown are thus made of high-strength seawater resistant German Submarine Steel.
This type of steel stands out not only for its extremely high strength and exceptional non-magnetic properties but also for its especially high resistance to seawater. The rotating bezel is designed so that it is captive in the case. As it may experience high levels of stress during use, the surface is hardened using TEGIMENT Technology, making it especially scratch-resistant.
These features make it clear that the U50 is perfectly suited to diving use – a fact that has been verified by the classification company DNV GL. 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.
