I've driven "quartz movement" clocks with one pps signals, bypassing the "quartz" works. To synchronize pendula (?) is relatively simple, but best done using a mechanical/magnetic impulse phase locked loop, considering the pendulum as a VCO. BTW, I recommend Stephenson's new effort, "Anathem" loosely based on the clock of the Long Now Foundation, q.v. Don Latham
