It has been many, many, years ago since I have dismantled such a clock.
IIRC there is an electromagnet inside that rewinds the coil spring when it is
out of action.
This happens every 5 minutes or so, causing the clock to 'click'.
There is no mention of 'quartz' on the face of the clock, so it is not an
electronic one.
Come to think of it, probably the contact breaker points for the magnet inside
the clock are corroded
(as was the case with the engine distributor, the car would not run initially
since having been standing for over 20 years. Cleaning the CB points cleared
that problem.
They were replaced shortly after, of course).
So, I'm now thinking of trying an electrical trick first, before dismantling.
I'll keep you informed.
