The question. Is it generally considered bad practice to press a pusher on a watch which ran out of power while the chronograph was running?
Scenario. I did this with a speedmaster that was until that moment, functioning flawlessly. That was then. Now, it's just a very busy three hander.
It shouldn't do any harm. I have often pressed the pushers on a wound down chronograph. If anything it sometimes starts the watch again for a few seconds.
A chronograph usually stops when wound down just as the minute recorder is about to advance because that requires a little more force from the mainspring. It may just be a coincidence that some other fault has shown itself.
