I was planning on starting a new thread & linking this to it, but couldn't figure out how to...

Anyway, my question is:
Is there a degree of how dead a clock is?

I have one clock that the second hand goes for a quarter of a lap when you activate the adjuster knob
one clock goes for about 3 or 4 seconds
one clock that does stuff all

Or would they all need the same amount of work/parts?
any ideas?

thanks in advance
Max
