With the 140 A S Anniversary, limited to 300 pieces, we celebrate the 65th anniversary of our company. At the same time, this timepiece continues the legacy of a model series that made both watchmaking and space flight history.

During the D1 Spacelab mission in 1985, physicist and astronaut Reinhard Furrer wore a 140 S equipped with the Lemania 5100 movement on his wrist. Under real mission conditions, it demonstrated that a self-winding mechanical chronograph functions reliably even in zero gravity. To this day, the 140 model series remains one of the most historically significant collections in the history of our company.

With the 140 A S Anniversary, we continue the technical evolution of this legendary chronograph. At its heart is the SINN Chronograph Movement SZ01. The defining feature of this proprietary development is the centre-mounted 60-minute stopwatch hand with a jumping minute indication. This design enables particularly fast and unambiguous reading of recorded times. It is complemented by the minute scale extending around the full diameter of the dial. Both the minute and second stopwatch hands are coated with luminescent colour, ensuring optimum readability.

The 140 A S Anniversary also stands out through its distinctive case finish. The combination of polished and satinised surfaces gives the watch a distinctive appearance while underscoring the exclusive character of this anniversary model. Thanks to TEGIMENT Technology, the case is especially scratch-resistant. The push-pieces and crown are equipped with the D3-System, while Ar-Dehumidifying Technology enhances functional reliability and freedom from fogging. Water-resistant and pressure-resistant to 10 bar, as well as resistant to low pressure, the watch offers a comprehensive package of technical performance.

The 140 A S Anniversary combines historical authenticity with technical advancement, resulting in a technically sophisticated chronograph with unmistakable heritage and a clear instrument-watch character.
