I received this cuckoo clock via Fedex yesterday and it was packed/insulated to perfection, so no worries there... movement had been cleaned/oiled and as far as I can tell, there are no obvious issues with it, at least to my novice eye. Hung the weights and it took right off. I manually moved the minute hand to hear the gong and the cuckoo sound on the hour and 1/2 hour. All good. Then I walked away from it and never heard another cuckoo call... and the hands had not moved! What the heck could be wrong? The seller is reputable and I know the clock was working fine before I got it. I am providing some views of the rear side of the movement. I am hoping a member can scrutinize the photos and maybe detect 'something that is off' with this little 30 hour movement. Many thanks for your expertise!
