Once upon a time, I synced a 200+ year old grandfather clock to a GPS 1PPS output. It used a PIC to convert the 1PPS signal to a 24 pulse per minute (if I remember correctly) signal to a model airplane servo. The servo just nudged the (optically sensed) pendulum. It pretty much worked the first time. The mods to the clock were done in such a way that no changes were made to the clock or case.
I considered adding an auto-winder to it...
