The Heart of the Heart
The hairspring is the most critical component in a mechanical watch. It controls the oscillation of the balance wheel.
How the Hairspring Works
- Hairspring is attached to the balance wheel
- When the balance wheel swings, the hairspring coils and uncoils
- This stores and releases energy
- The hairspring determines the oscillation rate
