Girard Perregaux Constant Escapement L.M. 48mm Mens Watch 93500-53-131-BA6C

Girard Perregaux  has developed an unique & mesmerizing response to an age-old challenge experienced with traditional mechanical movements. The escapement is the component that transfers the energy from the mainspring to the balance wheel, the regulating mechanism of the watch. A traditional lever escapement will mirror the amount of power it receives from the mainspring to the balance wheel. When the mainspring is fully wound a higher amount of energy is transferred to the escapement, which results in higher energy being transmitted to the balance wheel, which in turn will cause the watch to run a little faster. On the flip side, as the mainspring winds down a corresponding drop in power is being transmitted from the escapement lever to the balance wheel, which results in a lower amplitude & slowing-down of the watch.
Girard Perregaux’s Constant Force Escapement features an escapement mechanism that transmits power to the balance wheel at a constant force regardless of the state of wind of the mainspring. The escapement features a cage made of silicon with an ultra-thin blade at the center (only 14 microns thick, 6 times thinner than a strand of hair) that buckles up & down. The blade will only buckle when a very specific amount of pressure is applied to it. As the pressure builds from the unwinding of the mainspring the blade will buckle, with each buckle it creates an equal amount of force is transmitted to the balance wheel, thus propelling the movement forward.
