Sinn Watch 140 St Leather. The chronographs of the series 140 and 142 belong to our most illustrious timepieces. They have gone down in both watchmaking and space flight history. The German physicist and astronaut Reinhard Furrer wore the 140 S with Lemania 5100 movement on his wrist during the D1 Spacelab Mission in 1985. He was therefore able to demonstrate that automatic watches can function even in a weightless environment. In 1992 the astronaut Klaus Dietrich Flade took his 142 S along with him on the Mir 92 mission. We have now subjected the 140 model series to further technical development. It incorporates the SINN SZ01 chronograph movement. The most striking feature of the new design is the centre mounted jump 60 minute stopwatch hand for improved readability. The bead blasted stainless steel case is surface hardened with TEGIMENT Technology, making it especially scratch resistant. The 140 St incorporate Ar Dehumidifying Technology to increase the functional reliability and prevent fogging.
