Some of you may have seen my post of my very nice Kody where the lug snapped when I was fitting a new strap to it. Well I just got hold of a "dead" KODY which I'd hoped would enable me to recase it. Unfortunately it was about 1.5mm to small for the face, but as it was cosmetically excellent I turned my attention to the movement, a very dry looking 1950's ETA 1080 series. There is absolutely no resistance at all when winding, so my thought was a broken mainspring. However, when I then reset and advance the hands a little the watch will run for 5 or 10 seconds at a time, and will restart in the same way if I advance the hands a little again.
As the number of trustworthy watchmakers round here can be counted on the fingers of an earthworm I would need to send it away to be fixed, so I'd like some idea of what the potential faults might be.
