A Mid Size 37mm Sinn U200 SDR

U200 SDR diving watches were launched in 2010 and feature a smaller case size (37mm) than other timepieces having similar functionalities. Sinn diving timepieces are different from others available on the market because of the usage of submarine steel. The U200 SDR is protected from magnetic influences, extreme temperatures, high and low pressure and water. Additional functionalities include captive diver's bezel with minute ratcheting, crown at 4 o'clock, mission timer design, luminous dial elements and scratch-resistant sapphire crystal glass with anti-reflective coating.
