Hello, I am trying to fix a twisted and bent hair spring. I am not worry about bent. but I have no idea how to twist the spring. You will see the spring is rising up from the center. Why all the spring rising up from inside to the outside uniformly. Where should I twist the hairspring? Thank you very much for advice. This is a PP 16-250 lady movement. The balance is so small. The hair spring could not removed from the balance staff as it is very tight. I have to fix the twist hairspring with the balance wheel and staff. Thank you very much for the advice. David
