Different Cuckoo clock movements by: Grant
HI Im grant Im 19 learning to be a horologist now you said the movement may be a regula 25 it is.in 1 day cuckoo clocks mostly always have that movement now if it was an 8 day the movement would be a regula 34. But pictures would be good so others can see what you have but Shieder cuckoo clocks are my favorite and some can be worth alot lol
