The Swiss Lever
The escapement fork (pallet fork) is the component that controls energy release in a mechanical watch. Here is how it works.
How the Pallet Fork Works
- Balance wheel swings and pushes the pallet fork
- Pallet fork alternately locks and releases the escape wheel
- Each lock-release cycle is one tick
- This creates the characteristic ticking sound
