Got a friend's beautiful table clock to clean. It's powered by an 8-day Swiss PW movement with a larger than normal spring. Problem is the movement had been dunked in the past WITH the spring barrel in place. I saw a puddle of green gelatin beneath the barrel and all suspicions were confirmed when the barrel cover was removed...more green goo! Problem is my Marshall spring winder is not large enough to handle this spring. Although manual spring insertion is normally frowned upon, do I have any alternatives?
