Sinn U1 S L Limited Edition 1010.0243 Silicone

When absolute readability becomes the priority, the U1 S L demonstrates what is technically possible.

Limited to just 300 pieces, this exceptional diving watch combines maximum functionality with innovative luminosity – even in complete darkness.

The highlight: the entire dial and the main marker on the rotating bezel glow intensely. 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!

The U1 S L also makes a powerful visual statement: with its distinctive design language and clearly reduced display, it can be worn at any time – even outside the water.

Behind the striking appearance lies pure SINN technology: case and crown are made of high-strength, non-magnetic submarine steel, renowned for its exceptional seawater resistance. The high-quality Black Hard Coating, based on TEGIMENT Technology, provides a stylish look. And because reliability at SINN knows no compromise, the bezel is non-detachable and securely captive into the case.

Tested? Of course. An independent testing institute has certified the pressure resistance to a diving depth of 1,000 m (= 100 bar), as well as temperature resistance and functionality based on European diving equipment standards. The U1 S L is therefore a watch with real depth. In every respect.
