    Angelus Chronodato help

    Trying to bring back to life a chronodato. Right now have a balance/ run issue. Runs like a champ in all positions until flipping from movement up to movement down. Stops running as I turn just paste 180 dgrees DD to DU. positioned a mirror below and notice the balance continues to rotate freely and stops. The pallet fork stops moving as if no longer in contact with the balance. Not a lot of play in the balance. There is a broken screw in the cap jewel retainer, but I have it really tight with just the one screw. Is the balance to fork clearance that close, or maybe a balance jewel issue? Something else? appreciate any help. Thanks Dennis

    Have you checked that the top and bottom balance jewels aren't damaged and also the balance pivots are in good condition.

    I would also take the balance out and test that the fork still has power behind it by moving it and seeing if it continues to the other side on its own as if not then its something from the wheels ( which I would start checking endshake and side shake of)

    Hope some of my ramblings make sense

    yes very helpful The pallet moves freely
    in fact I can manipulate a train wheel with a tweezer and get the entire train moving. it's a bit quick without the balance though..
    The cap jewel, plate jewels are good. Is it possible that the upper cap jewel has lost some clearance ,(being a broken screw),to the upper balance pivot allowing the entire balance to move away from the pallet jewels when turned upside down, causing the disconnect ?

    You should be able to see it upside down if it engages . if you can maybe remove the balance spring then you can check the balance a bit better.

    Something has come to mind, is the roller jewel on the balance pointing down the line of the gear train (in beat)

    after checking your suggestions, on further examining, I found the impulse jewel loose. Moved up just enough to let it run dial down, but dial up and the impulse didn't contact the pallet fork. Reset and am testing now for long run time thanks again

    No worries, it was all you, when you have a problem like this you just break every part into segments and check individually until you find the fault
