I'm not a watchmaker, but what you are describing is how regulation was done in the pre-WWII period. Since the postwar period, most watchmakers have electronic timing machines that give the rate of the watch instantly. Typically they will test the watch in a few positions, set a rate that leaves the watch running a little fast and leave it at that - this is done in a matter of minutes, not days.

Hello, all, and my question is for the watch makers in the group:
When the customary cleaning and oiling has been completed on a mechanical
wristwatch and the watch has been reassembled and ticking how much time is
spent on regulation before returning the watch to the customer? Ignoring
for a moment any effect(s) introduced by the watch being worn on the
owner's wrist I was thinking that it might take at least several days of
continuous operation to find that sweet spot on the speed adjustment.
Thanks for your comment and time.
