Sinn U50 SL Limited Edition Diving Watch 1050.0203 H Bracelet

$5,590.00 CAD

Never lose track of time – especially in the dark. Limited to 500 pieces, our U50 S L model embodies this aspiration in a special way. For example, the entire dial and key marker on the rotating bezel glow and not, as is normally the case, just the indices and hands. This is made possible by the unusual luminous paint application on the dial. In terms of its production, an innovative method is used to incorporate the luminous paint into a mould using a special casting process. After hardening, a hybrid ceramic component is created, which is joined to the metallic base dial. In the final processing step, the two combined components are printed. The result is rather remarkable – thanks to the high concentration and large surface area of the luminous paint, we achieve extreme luminosity and thus perfect readability – in a quality never seen before! In terms of appearance, the watch boasts a striking design with a display that concentrates on the essentials, realized in a comfortable diameter size of 41 mm! Another plus: outstanding suitability for everyday use. The case and crown are made of high-strength seawater-resistant German Submarine Steel. The Black Hard Coating of the case, crown and rotating bezel skillfully showcases this unusual look and forms a perfect contrast to the dial. Furthermore, thanks to TEGIMENT technology, a special hardening process for Submarine Steel, the Black Hard Coating is extremely scratch-resistant. We have designed the rotating bezel so that it is captive in the case.

There is no doubt that the U50 S L is well equipped – as confirmed by the DNV. This independent classification company verifies and certifies pressure resistance to a diving depth of 500 meters (= 50 bar) and temperature resistance and functionality in accordance with the European diving equipment standards.
