·Hello OF!
I have a 26,55X,XXX 321 movement from a 145.012-67 that I am rebuilding. The balance wheel has damaged pinons and the roller table is missing. I see it's part number 1324/6527 and i was hoping to see if there are other movements that used this same roller table so I can broaden my search for one. The documentation that I have on the 320/321 does not seem to list the roller table individually. Is it part of a larger family or specific to the 320/321/CH27.
Side question - I read somewhere (likely here) that the hairsprings and balance wheels were matched up at the factory based on tests - would it be unwise to just use another donor balance wheel with serviceable balance staff and throw another donor hairspring?
Thanks!
Zack
