Sinn U1 SDR Leather Watch 1010.040 Leather

The Sinn U1 SDR Leather Watch 1010.040 Leather is a rugged diving watch designed to withstand extreme underwater conditions while offering a refined appearance. Crafted from genuine German Submarine Steel, the 44mm case delivers exceptional resistance to seawater corrosion and mechanical stress. The black hard coated captive diver’s bezel, treated with Sinn’s TEGIMENT technology, ensures superior scratch resistance and long-lasting durability. Paired with a classic black leather strap, this Sinn U1 SDR watch combines professional functionality with everyday wearability.

The matte black dial of the Sinn U1 SDR Watch 1010.040 is engineered for optimal readability, featuring luminous hands and indices that ensure clear visibility in low light and underwater environments. The bold red seconds hand enhances legibility, allowing for quick and precise time tracking. Powered by the dependable SW200-1 automatic movement, the watch offers accurate hour, minute, seconds and date functions. A screw-down crown, solid case back and sapphire crystal glass ensure an impressive water resistance of 1000 metres, meeting strict European diving standards. The Sinn U1 SDR Leather Watch 1010.040 is a perfect balance of durability, precision and style.
