Engineered in Frankfurt for pilots, divers and astronauts, Sinn crafts instruments of uncompromising function and quiet, enduring distinction.
Founded by Helmut Sinn.
In 1994 the company passed to Lothar Schmidt, who carried forward its devotion to functional, precise instruments built for professional use.
The U1 diver's case and crown are crafted from German Submarine Steel, the seawater resistant steel used for the hulls of German Navy class 212 submarines.
The U1 is rated to 1,000 metres, with water and pressure resistance certified by DNV to European diving equipment standards using a 125 bar test.
A Sinn 140 S chronograph was worn in space by astronaut Reinhard Furrer on the Spacelab D1 mission in 1985.
The diver's bezel clicks round as the bubbles rise from the deep.
