Use a timegrapher just to determine whether it's time for a service?
I'm going to buy my first valuable automatic watch (probably a Mido Ocean 200) and I am quite concerned about the service/intervals.
Would it be senseful to use a timegrapher like the Weishi 1000/1900 to monitor deviations in amplitude a.s.o. to determine when it's time for a service?
I am not going to service the watch myself, but I would give it to some professional watchmaker.
Thanks.
