My experience in the 1960's was that
it seemed like I don't remember any
car with one of these clocks that ever
worked reliably.  Meaning, the time would
typically be way off, by hours.  I would
correct the time, and the clock would
run OK temporarily, but within a few
days, was way off again.  I also
remember that these faulty clocks would
nevertheless startle me when the solenoid
fired.  It was LOUD.  At the time, I didn't
know what the sound was due to.  So it was not like
the clock didn't even run.  Just a guess, but
perhaps the solenoid didn't fire reliably over
the wide temperature range the car experienced.
At least -30 degrees F to +150 degrees F.
