A monochrome design with black case and unusual blue and black gradient dial to match – limited to 500 pieces, the Model U50 S BS promises an exciting watch at very first glance! The Black Hard Coating on a TEGIMENT Technology basis lends the watch a high-quality, professional look. This combination is also the most durable form of black coating feasible according to the latest advancements in technology. As a sturdy and precise timepiece, the watch also meets the requirements of professional divers for maximum reliability and clear readability. Thanks to these attributes, the U50 S BS also often proves to be an additional safety device with pragmatic features, such as a case made of high-strength seawater-resistant German Submarine Steel. Those in the know immediately know: this lends the watch exceptional high strength and outstanding non-magnetic properties. The captive rotating bezel prevents the loss of set times.
