Description

The Constant Escapement, a revolutionary concept addressing a holy grail of watchmaking, constant force. A breakthrough in the field of chronometry with a completely new architecture and design of the escapement (3 different patents). The name, in addition to being a nod to one of the Maison\u2019s historical figures, Constant Girard-Perregaux, also refers to a holy grail in mechanical watchmaking that has perplexed watchmakers since the dawn of time: the constant force.\tUnprecedented precision: a victory over waning power in traditional mechanical watches, through constant power delivery to the oscillator meaning constant amplitude and constant rate.\tAvant-garde materials and advanced technology. Use of a 14 micron silicon buckled-blade, a strategic component 6 times thinner than a human hair. This blade acts as an energy micro storage unit that compensates for the variable energy of the barrel by giving constant impulses to the oscillator.\tLong power reserve and linear indicator due to an innovative double twin barrel (patent pending). A total length of 3 meters of barrel spring.\tThe Constant Escapement stands out with its resolutely technical and contemporary design, with a tribute to Girard-Perregaux\u2019s codes and creative tradition. The movement takes its place in a comfortable round 48.00 mm diameter case in white gold with a curved case band. To offer maximum visibility to the escapement itself, with its butterfly wing frame and the vibrating blade in its central axis, the hours and minutes occupy a sub-dial off-centered at 12 o\u2019clock. This is flanked by the two energy reservoirs in the shape of the double barrels. Logically linear, the power reserve indicator is placed at 9 o\u2019clock.\t\xa0
