Replacement clockwork for a sawtooth or gravity clock from Warmink marked ANNO 1750 in the dial. There are 2 types of clockworks, this one is 2″ or 5 cm tall. Work is overhauled and is tested and running. Keep in mind these are delicate clockworks and some skills are required to get it running. Clockwork is complete only the hour pipe need to be replaced from the old clockwork.
