Hi Peter, I had a Hampden 108 that did the same thing. Take a bright light and look at the top of the balance staff where it comes through the crown or upper jewel. Apply very light pressure on and off the balance wheel to while watching the top of the balance staff and see how much play if any there is. Mine had too much play and after replacing the upper jewel everything was fine. If that is not the problem I have not got a clue. Harry | |||
