The Pallet Lever

Reference no 710



The escapement, Escape Wheel and Pallet Lever (710), together with the balance system is the real heart of the movement. The Escape Wheel and the Pallet Lever together perform two different but equally important tasks: to control the rate by which the Mainspring unwinds (oscillator with a stable frequency) and to repeatedly give the Balance Wheel its needed impulse.




The two tasks are implemented by the geometry of the Pallet Jewels and Escape Wheel teeth. In the figure one Pallet Jewel is standing on one Escape Wheel tooth. The Escape Wheel is the last wheel in the wheel train that is powered by the Mainspring.


  The size comparison with a match really emphasize how small parts there are in the movement.
