The History of the Constant Escapement L.M.

The Constant Escapement L.M. offers a new and convincing solution to the watchmakers’ age-old concern: the precision and regularity of the functioning of a mechanical watch. It took over eight years of research and development to firmly and reliably establish this system so as to apply an instant and continuous “constant force”. Its name pays tribute to two emblematic figures of the company; its founder, Constant Girard-Perregaux, and Luigi Macaluso who decided to promote this movement which was introduced as a working prototype in 2008.

The Calibre GP09100-0004

It states, whatever the energy of the barrel, the escapement will transmit a constant energy to the regulator (or balance). In order to do so, the idea was to integrate a silicon intermediary device into the escapement which contained an extremely thin blade, accumulating energy up to a threshold close to instability; always the same. It then transmits this energy completely and instantly.
