Hi everyone, I was recently trying to restore this Swiss Pocket Watch movement. Tried to reposition the click spring, and it flew off, never to be found again. Believe me, I looked everywhere. Anyway, how would I identify the size of the spring? I don't want to randomly buy click springs hoping I get one that fits. See attached watch. It runs great if I wind it and manually engage the ratchet, but not the way it is suppose to run. Also, I can't seem to find any movements associated with the engraved name on the movement.
