Advanced Timegrapher Reading
Beyond basic accuracy, timegraphers reveal deeper health indicators. Here is what advanced readings tell you.
The Four Key Readings
- Rate: seconds gained/lost per day — the obvious metric
- Amplitude: how far the balance swings — 270-310° is healthy
- Beat error: asymmetry in tick-tock — should be under 0.5ms
- Beat rate: actual vph — should match spec (21,600 or 28,800)
What Each Reading Reveals
| Reading | Normal | Problem |
|---|---|---|
| Rate | +/- 10 sec/day | +/- 30+ sec/day |
| Amplitude | 270-310° | Below 250° = dried oil or weak mainspring |
| Beat error | Under 0.5ms | Over 1.0ms = hairspring issue |
| Beat rate | Matches spec | Off-spec = potential movement damage |
Positional Testing
A proper timegrapher test checks five positions: dial up, dial down, crown up, crown down, crown left. Compare readings across positions — consistency matters more than any single position's accuracy.
Frequently Asked Questions
Should I regulate based on timegrapher?
Only if you have experience — incorrect regulation can worsen performance. See our regulation guide.
Where can I get my watch tested?
Most watchmakers offer timegrapher testing for free or minimal cost.
