GIRARD-PERREGAUX CONSTANT ESCAPEMENT L.M. 2017
Girard-perregaux’s new Constant Escapement L.M. model features a design that is more technical and contemporary. The initials “L.M.” stand for Luigi Macaluso (1948-2010), who was the president of the Sowind Group owning the brand and the one who decided to trust and promote this movement. Protected by four invention patents, the new Constant Escapement L.M. features a butterfly-wing frame placed between the lever and the balance spring. This intermediate device serves to support a buckledblade measuring just 14 microns thick – six times finer than a human hair. With two double barrels, comprising springs amounting to a total three metres in length, ensure an exceptional one-week power reserve displayed on a linear indicator at 9 o’clock. Hours and minutes are read off on an offset counter at 12 o’clock. To ensure an unobstructed view of this mechanism, only the seconds hand remains centrally fitted. The GP09100 movement beats at a frequency of 3 Hz (21,600 vph). The imposing 46 mm-diameter x 14.84 mm-thickness case is water-resistant to 30 metres.
