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.
