Re: SF240 hairspring
I called them, there is no collet and stud. You will have to time it to the balance as well, length and so on.

Did they give the reference of the SF240 hairspring in their catalog?

Re: SF240 hairspring
In my search for a hairspring I couldn´t find this page. Did they advice which spring would be possible to work for timing and adjustment? Collets and pins I still should have.
I also wrote them an email, but they weren´t confident to advice one. Maybe with your wisedom Yoda you could get another answer

Re: SF240 hairspring
I know, the best way is to measure width, thickness and length of the damaged hairspring and take it from there.
It's been a long time since I timed a hairspring and I am not sure that I long to do it again.
