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.
