GIRARD-PERREGAUX – CONSTANT ESCAPEMENT
Instead of wheels, levers and springs used in conventional timepieces, the Constant Escapement features a lipshaped silicon frame with a buckle-blade, six times thinner than a strand of human hair, running through its centre. The wave-like motion of the blade, which constantly pops up and down, stores and releases energy at regular intervals to ensure steady and undulating precision.
Two nickel escape wheels transmit energy
to the silicon blade
A lever underneath the bridge swings left to right, engaging and releasing an impulse pin at a constant
rate to regulate the timing
The silicon blade stores and disperses the energy in pulses. The constant wave-like pulses of the blade set the
lever in motion
