I'm betting the pendulum plunges through the coil? In that case, not a
quartz clock, but a mechanical clock that uses the oscillator to power it
instead of a spring. The coil is the most critical part, and I would check
for continuity - how many ohms is it? The rest of the parts are easy, but if
the coil is open or shorted you are in big trouble.

Thanks for the tip, I'm going to check out the capacitor first and
hope it's not the coil !
