Timing
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 changed on the machine.
Hope this helps.
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. Ampl...

Nature isn't perfect...
Without being there it is difficult to say, but in general: For the timing, there are some possibilities. That could be the measurement error of the Witschi machine, I have never seen the specs of a Witschi, so I don't know. Also any real oscillator such ...
Thenk you for your answer, Don!
I do not know the angle of the 5070 and, unfortunately, I didn't care about this indicator. I will make a more documented measurement and get back. Thank you for your help! Radu
