technical question
Deal fellow collectors,
I hope I am addressing my question to the right community.
I tested today on a Witschi machine a watch supposed to beat at a frequency of 18.000 and I was surprised to see that, fully wound, its frequency was 17.997 to 18.002. Amplitude was very high also, 330-340. Can anyone explain the possible reason of this facts?
Best,
R

To get a correct reading you should have the Beat Mode on your machine set at automatic (this will automatically detect BPH), and to get an accurate amplitude reading you will need to know the lift angle of the movement you are testing lift angle can be c...
