I have a Lecoultre memovox manual wind watch with alarm and date with cal. 911 movement. It usually stops after 23 hours. How many revos should I wind it? I usually do about 30 revos. How many is too many? I've been told you cant overwind it, is that true? I have not come to a point where the watch stops winding, am I not winding it enough? How long should it stay functioning with a full mainspring?
