Gentlemen, today I would like to propose a question that may be a bit OOT for the group but I became interested in it:
Watchbuilders and juwellers use an instrument to measure the accuracy of mechanical watches. I am not aware of the correct name for this instrument in English but in German it is called a "Zeitwaage" and my internet translator calls it a "timing maschine". For mechanical watches the timing maschine uses a microphone to detect the acustical impulses of the balance spring (correct word?) and compares it to a xtal. Some research has shown that there is an comparable instrument for ANALOG quarz watches. As far as I understand it does not try to detect the quarz frequency but detects magnetic pulses from the step motors that move the hands of the watch. Has anyone of you ever tried to do this in a time nuts laboratory?
