    hello everyone, watch running real fast

    I hope you all can help me with this. I'm sure you can. I am a novice at repairing pocketwatches. I have a Longines that is running real fast. It gains about 2 hours in 12 hours. I think it might be magnetized but I don't own a demagnetizer. I also think it might be more than just magnetism. It runs beautifully except that. Thanks for the help, I hope.

    "Hello?"

    "Hello. Is your watch running?"

    "Why yes it is, and very fast."

    "Well, you better go catch it!"



    Okay, seriously - it may be magnetized but it may also need a service. If the train is not lubricated, it won't turn correctly. If it doesn't turn correctly, it won't fully transfer the power from the mainspring to the escapement. This means the balance & hairspring assembly won't rotate to it's full amplitude. When that happens, the watch can tick faster than intended since it takes less time for a back & forth oscillation of, say, 170˚ than one of 280˚.

    Something is causing the hairspring to operate at a much shorter effective length than it normally would. Or said another way something is holding two or more hairspring coils together. That something could be magnetism, a speck of dust, hair or oil. A watch repairman should be able to sort it out for you in short order.
