Well if that,s the case then...that "you can,t over wind a clock unless its 300/400 years old"...i,ll be have a few choice words with our local jeweller/clock repairer...who charged us £25 to unwind an overwound 1920,s mantle clock....and i,m going to print off what you have said...just for backup...and i,ll be demanding my money back.....thankyou for that info....
