      I have purchased a GUB09207211 hairspring from Cousins watch parts and I am not sure how to attached it to the anchor on the balance cock. Is there a tool I should use or is there a method that I can employ. Any help is appreciated Thanks.

      Hi everyone, I have some problems with a manual winding watch. It needs some work but I would try to do it myself. The watch appears fully wound but it doesn't work. Which is the problem? Thank you in advance

      I work a lot on small caliber (ladies watch size) movements but still have mishaps with the balance hairspring.  These hairsprings are very fragile and easily bent and removing/replacing the balance assembly seems to be my problem.  I would like any comments on the risks of deforming the hairspring by allowing the wheel to dangle during handling.  I would also like to know if the position of the regulator arm/pins has any effect re risk of deforming the spring, should it be close to the stud or as far a possible from the stud, I normally leave it where I find it so the timing is close to what it was before dis-assembly.  Any advice on techniques etc will be much appreciated.

      I am correcting a deformed hairspring and need to set the curve for the regulator pins.  De Carle mentions using curve-forming tweezers, which I cannot yet find.  What are the alternate practices for forming this curved portion of the over curve?
      Thanks,

      Question for those who work on Vintage Timex watches:
      I've restored several Timex pieces from the late '60s to the late '70s.  The technique I learned (from Internet posts and tutorials) say to simply loosen the dial-side balance pivot by unscrewing it 1/2 turn prior to cleaning the entire movement in an ultrasonic cleaner.  This method contradicts the official Timex service manuals, which state that the balance should be removed, cleaned separately and reinstalled.  Thus preventing the hairspring form being damaged in the ultrasonic cleaner.
      My experience is this: 
      Leaving the balance in place (slightly loosened) is much easier and will work on the standard movements used in the '70s (M24/25, M32/33, M104, etc.) Attempting the same method on movements from the '50s and '60s (M22, M29, etc) will result in a kinked hairspring that is damn near impossible to un-kink.  So my question is this:
      What do you experienced Timex restoration experts recommend?  Leave the balance/hairspring in the movement for cleaning, or take it out to soak in a separate jar?
      Is the potential for hairspring damage greater when removing/reinstalling the balance - in comparison to leaving it in place?
      I've messed up a couple of vintage movements that I really wish I hadn't.   I don't want to make those mistakes again.
      Thanks for any insights!

    • Impressive artistic impression in your presentation already.  Should not underestimate your aptitute handling tasks as you do, no doubt on your way to acheiving masterhood.  Best wishes.
    • That's awesome! I'm going to try that on some of my scrap bin parts and so how it goes. I've already got everything on hand except for the denatured alcohol. I'll have to pick some up on my next run to town. All of what we have now is "good natured alcohol".
    • Not strictly correct. It is indeed the impulse jewel that knocks the pallet out of lock, however once the escape wheel tooth is sliding down the impulse face of the pallet stone it is the pallet that is accelerating the impulse jewel. So both pallet and impulse jewel take it in turns to make each other move.
    • Hmm so OP probably put the new spring fairly close to where the old one was, but the roller is still out of place. When the balance is at rest, with the fork engaged with the roller, fork between the bankings, the balance arms should be perpendicular to a line drawn from escape jewel to balance jewel. They should really realign the roller, then get the hairspring oriented correctly.
    • Right. But looking at the mov't picture from Ranfft's, the pallet sits inline with the cock screw and the balance. And in the OP picture the impulse jewel is inline with the same said reference points. That should make so that the jewel is in the proper position are when the balance in installed, and the watch should at least run anyway.
