Timegrapher measurement

During measurement, the following values were recorded:

Rate deviation: -9 seconds per day
Amplitude: 286°
Beat error: 0.7 ms
Lift angle: 52.0°
Frequency: 25,200 A/h

The measured amplitude is decent. The deviation of -9 seconds per day and beat error of 0.7 ms provide a usable impression of the current rate of the movement.

A timegrapher measurement is always a snapshot in one position and does not guarantee future accuracy or the complete technical condition of the movement.

The crown complements the shape and finish of the polished case nicely.
