WHAT WE LOVE:

The Sinn U1 SDR Tegiment Ref. 1010.050 is a professional-grade dive watch engineered for extreme conditions. Made in Germany and built with Sinns proprietary technologies, the U1 SDR stands out for its bold, utilitarian design and its uncompromising durability. The 44mm case is crafted from German submarine steel renowned for its superior saltwater resistance and treated with Sinns Tegiment technology to harden the surface and drastically increase scratch resistance.

The watch features a black rotating bezel with minute graduations, rendered in a matte black PVD coating (the “SDR” in the name stands for Schwarze Drehring, or “black rotating bezel”). The high-contrast black dial with white indices and red hands ensures quick readability, even in low visibility, and is protected by a thick sapphire crystal. A screw-down crown at 4 oclock and an integrated crown guard help keep the silhouette functional and ergonomic.

WHATS INSIDE:

At its core is the dependable Sellita SW200-1 automatic movement, offering hacking seconds, quickset date, and a 38-hour power reserve. While utilitarian in its function, its housed in a case thats been tested and certified for pressure resistance up to 1,000 meters (100 bar), in accordance with European diving equipment standards (EN 250 / EN 14143).
