Balance spring
(or hairspring)
A balance spring is a fine spiral or helical spring used in mechanical watches, marine chronometers, and other timekeeping mechanisms to control the rate of vibration of the balance wheel. A balance spring usually has a regulator lever to adjust the rate of the timepiece.
Types of balance springs
- flat spiral
- Breguet overcoil (Breguet spring)
- chronometer helix
- showing curving ends
- early balance springs
