Girard-Perregaux Constant Escapement L.M. Mechanical Watch

Girard-Perregaux Constant Escapement L.M. Mechanical Watch
Girard-Perregaux introduces an authentic technical revolution in its Haute Horlogerie collection: a constant escapement. Thanks to this innovation protected by three patents, the escapement delivers constant energy to the regulator, whatever the energy left in the barrel, in order to ensure the perfect regularity – and thus optimal precision – of the watch. To address the challenge of constant force that has preoccupied horologists down through the ages, the escapement has been fitted with an intermediary device fitted with a silicon buckled blade six times thinner than a human hair. The blade stores up the energy by being repeatedly flexed to a point as close as possible to its unstable state or buckling point, before releasing the exact same amount of energy each time and then tirelessly beginning all over again.
