Precision Testing
A timing machine (timegrapher) measures your watch accuracy with professional precision.
What It Measures
- Rate seconds gained or lost per day
- Amplitude how far the balance wheel swings
- Beat error symmetry of the balance swing
How It Works
- Place the watch on the microphone
- The machine listens to the ticking
- It calculates rate, amplitude, and beat error
- Display shows results in real time
Reading the Results
| Metric | Good | Excellent |
|---|---|---|
| Rate | +-10 sec/day | +-5 sec/day |
| Amplitude | 250-300 degrees | 275-315 degrees |
| Beat error | Less than 0.5ms | Less than 0.2ms |
