I have an 1891 Waltham pocket watch which I had serviced by a rather aged local horologist just over a year ago (new main spring full strip down etc.). Recently it has developed an odd problem, I wind it and it runs, however the hour and minute hands never turn. I can turn them and I don't feel any undue resistance (they adjust via a nut on the hand spindle) but they won't turn by themselves. I tried to take it back to the old gentleman and the shop has closed, apparently he's either gone bust or retired so I'm a bit stuffed for local help.
So my question is, is there anything obvious I could (carefully obviously) check before I start looking for another horologist on my Babbage engine?
