Sinn 142 St II

The 142 St II is a space chronograph by Sinn.

This chronograph is one of the model classics of Sinn: as first automatic chronograph it was worn in space by the German physicist and astronaut Dr. Reinhard Furrer during the D1 mission in 1985 and refuted impressively the claim that watches with automatic movement may not work in zero gravity.

To the 20th anniversary of this flight Sinn in 2005 launched a special edition with titanium case, limited to 500 pieces.
