Sinn U1 SDR Rubber Watch

Sinn U1 SDR Rubber Watch 1010.040

The Sinn U1 SDR Rubber Watch 1010.040 is a professional grade diving watch built to perform in the most extreme underwater environments. Constructed from genuine German Submarine Steel, the 44mm case provides exceptional resistance to seawater corrosion and mechanical stress, ensuring long term durability. The black hard coated captive diver’s bezel is enhanced with Sinn’s TEGIMENT technology, significantly increasing scratch resistance and maintaining its appearance over time. Paired with a durable black rubber strap, this Sinn U1 SDR delivers both comfort and reliability for extended use in demanding conditions.

The matte black dial of the Sinn U1 SDR Watch 1010.040 is designed for maximum clarity, featuring luminous hands and indices that provide excellent visibility in low light and underwater environments. A bold red seconds hand enhances readability, allowing for precise time tracking during dives. Powered by the reliable SW200-1 automatic movement, the watch offers accurate hour, minute, seconds and date functions. The screw down crown, solid case back and sapphire crystal glass contribute to an impressive water resistance of 1000 metres, meeting strict European diving equipment standards. Combining advanced engineering with rugged design, the Sinn U1 SDR Rubber Watch 1010.040 is a true professional diving instrument.
