I'm working on a vintage Bulova 10BAC and the breguet hairspring just won't cooperate. Can anyone with experience offer guidance/ideas?
The overcoil segment is contacting the concentric coils when dial down. I adjust the overcoil up near the regulator/stud and get clearance dial down, but then dial up the overcoil is contacting the cock. What can I do to make it right?
