The redesign of the technically refined space chronograph 140 resulted in the creation of the 140 A model (limited edition of just 500 timepieces) with silver electroplated counter dials and satinized stainless steel case with polished sides.
The 140 and 142 chronographs are two of 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 D-1 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-SZ01chronograph movement. The most striking feature of the new design is the centre-mounted jump 60-minute stop hand for improved readability. The stainless steel case is surface-hardened with TEGIMENT Technology, making it especially scratch-resistant. All of the 140 model series watches incorporate Ar-Dehumidifying Technology to increase the functional reliability and prevent fogging.
