Description

The chronographs of the series 140 and 142 belong to Sinn's 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.

Sinn has 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. This forms the base for the Black Hard Coating. The 140 St S incorporate Ar-Dehumidifying Technology to increase the functional reliability and prevent fogging.

Movement

The SZ01 movement is based on the successful Valjoux 7750 and has been specially developed by SINN. The development work began back in 2003.

The main priority in undertaking the redesign was to make the chronograph functions significantly easier to read off. Which is why Sinn attached so much importance to finding a first-class technical solution to mounting the jump 60-minute stopwatch hand in the centre of the dial. This allows users to take accurate stop times even more quickly and simply. The clarity and distinct readability of this chronograph stem from the design of the well-known Lemania 5100 movement.

Sinn's redesign enhances the readability in two ways: firstly, 60 minutes are now counted in one sweep of the hand instead of the usual 30 minutes, and secondly, the minute stop scale covers the entire diameter of the dial.
