THE ESCAPEMENT:
The Pallet Lever Geometry









A very precise geometry of the pallet lever (and escape wheel teeth) is required
to assure proper locking and impulse of the two pallets on escape wheel teeth. In the 28,800 beats per hour (bph) watch, each pallet executes both operations 14,400 times per hour. The Swiss success with the anchor escapement is
attributable to careful attention to this geometry and to precision of manufacture.
