Mechanical WW Need help ordering balance/HS for FHF 28

[Charlie Ryan]

Hi All

I'm a beginner. This is an FHF 28. While trying to unbend the hairspring, it came unpinned from the stud. I can't repin and easier to get a knew one.

Borel lists these parts. My understanding is that hairsprings are paired (tuned?) with their balance wheels. Is this the case? Are these parts both HS and balance wheel? I think I need the INCA part. What is the SSR part?




BTW, what's involved with repining a HS?

Thanks for any help

Charlie

Repinning a hairspring needs good eyesight, steady hands, the proper pin size and a way to vibrate the assembly after repairing it. rebending a harispring to proper condition is an art to say the least. It is best left to professionals if you have never done it before and the watch is an heirloom.

Balance complete means wheel and hairspring. You need the Incabloc type. SSR is another brand of shock protection (Super Shock Resist).
