Garrett,

About 10 years ago my clock quit and I was able to fix it.

These clocks are part electronic and part mechanical.  An electronic timing
circuit discharges a capacitor into a coil on a regular basis.  The pulsing
magnetism from the coil moves the mechanical part of the clock.  When mine
failed, I still observed a twitching on the second hand and thus I expected
to find a partially stripped gear.  What I did fine was that the capacitor
that discharges into the coil was bad.  I replaced it and the clock has run
just fine since.
