Sinn U1 SDR

Launched in 2005, the Sinn U1 SDR enjoys cult status with its autonomous and pragmatic design and mostly due to its seawater-resistant housing made of German submarine steel. This collection from the manufacturer is waterproof up to 1,000 metres (100 bar) and comes equipped with a captive black rotating bezel (SDR) with minute detent. The Sinn U1 SDR is a professional diver's watch that will provide you with reliable service on any underwater mission.
