Fusee main spring repaired

New postby brownsrplm » Mon Jan 18, 2016 4:15 pm

I have this 18s Fusee made approximately in 1853 with a Chester mark. It is complete with a good balance, chain is intact, however the main spring is broken or there is some other issue with winding it. It will not turn with a key, I have tried to let down the spring, but it does not move. My guess is, it is broken and lodged in the barrel to where it acts frozen (I've run into that before with American made watches). I'm not competent enough to do a tear-down on one of these and due to shakes, bad eyes etc these days I don't want to start on one! If you have an inclination for these please PM me about it...

To release the mainspring, you have to take the dial off. Have you done this? There is a small, usually black gear with a pawl held by a screw. You have to loosen the screw and then disengage the pawl from the gear. Holding the arbor with a properly sized key to control release works well. The key will be a smaller one than what you wind and set the watch with. It's also best to have the chain wound entirely on the spring barrel if possible. Removing the entire movement from the case is also advised.

I'm new at fusees myself but this is what I have found so far.
