The Heartbeat of Your Watch
The balance wheel oscillates back and forth at a precise rate, dividing time into equal intervals.
How It Works
- The mainspring provides energy through the gear train
- The escapement releases energy to the balance wheel
- The balance wheel oscillates back and forth
- Each swing advances the gear train by one tooth
Oscillation Rate
| Movement | Oscillation | Ticks/Sec |
|---|---|---|
| NH35 | 21,600 vph | 6 |
| NH34 | 21,600 vph | 6 |
What Affects Accuracy
- Position: watch runs differently face up vs face down
- Temperature: extreme cold or heat affects the hairspring
- Magnetism: magnets disrupt the balance wheel
- Power reserve: low power means less stable oscillation
