A very frustrating, yet rewarding restoration project - and on the "difficulty scale", this one was a solid 8 out of 10. 1880s French carriage clock, quarter repeater that came in in bits and pieces. It took me 2 months to identify what was missing and then to hand make parts, including wheel and pinion cutting. It has time, alarm and strike plus repeats (strike) hour and quarters on two gong rods.
Would I do it again? Who knows...
The point I am trying to make here is : repairing wrist watches is too easy :-) Keep your minds open, there is plenty to collect, to preserve for the future and to enjoy now.
