I have a number of older 3133 chronographs which have what seems to be a common problem: the chronograph seconds hand fails to reset to zero. My friendly local watchmaker can only fix this problem temporarily; after a few uses of the chronograph it reappears. The good news is that he does not charge me for these small repairs. The bad news is that the problem reccurs and he has other (and more profitable) things to do. Is there a more permanent remedy for this? I know the question is probably too general but any help would be appreciated.
Also, the same friendly watchmaker has asked me to try and find a technical manual of sorts for 3133 service. Do any of you know of such a thing?
Interestinly enough, a couple of 3017 I have don't have this proble and are much smoother to operate.
