Elgin 3/0 Movement Runs Fast

[SockMonkey72]

Hello still new here and learning a lot. Taking Mark's courses and reading a lot of books. Ok so I purchased a few Elgin 3/0 movements to practice on. So after a strip and clean and oil. The movement runs about 10 minuets fast in 12 hours? I checked the hairspring, it's between the regulator pins, no coils are touching? The balacnce staff is true. I demagnetized a few times. Still the same result. Any advice or suggestions?

Thanks

Check staffs end shake,  Approximate amplitute. Check hairsprings possible contact with spokes. Forks arbor end shake, forks clearance from roller etc.

If all checks alright, short h/s.

Do you have leftover hairspring after the stud? You may be able to lengthen the hairspring. I have a hairspring vibrating tool that is great for that job.

How do you test that you have demagnetised correctly.

Vinn, I know how to do it I’ve got an Elma antimag but I think a lot of people think they have demagnetised a watch but haven’t, just asking really if they test it with a compass afterwards, I bet most people don’t have a compass.

   yes you need a compass (very small ) or something to indicate a magnetic  field.  vin
