Most specifically where can I find hairsprings for the 6497/98 and Unitas equivalents. I am embarked on a hairspring class and would like several uncolleted and unstudded springs with which to practice. -
Where would one even start with this mess? Trying to put the balance in after cleaning everything, one small slip, and in less than a second: disaster. Comes from not having 100% focus at the end of a day I guess. "No Excuse Sir!"

I need help with removing and then putting back in a hairspring that has a friction fit stud. I know there is a special tool one can use for this purpose. Does anyone have any pictures and know who might have made it? Can anyone "walk me through" how to remove and replace a hairspring without using the tool? Thanks!

I recently bought at auction a 1950 Jaeger LeCoultre manual wind watch which during viewing was working and keeping good time. Having received the watch it was found to be not working . Upon closer examination I discovered the hairspring has broken just short of the outer stud attachment. anyone got any ideas or technique for re-attaching the end of the hair spring to the triangular stud???? It is incredibly small and quite a slippery thing to hold onto which makes it near impossible to remove the holding pin and re-insert the end of the spring.

I recently encountered a balance assembly in which the hairspring appears to be cemented into a grove in the stud. (Actually, I have several watch movements of this type.) There doesn't appear to be any way to unscrew the stud; nor is there any room to pry it off. This is on an inexpensive EB movement. How does one remove the hairspring from the balance cock in these cases? Is a special tool required? Thanks!
