  1. Question about fragility of hairspring

    Thanks for the replies. One learns by making mistakes, but in this case I think I’ve been lucky.
  2. Hi all. I have a question about the fragility of hairsprings. I’m completely new to watch repair, and have started by regulating my mechanical watches (Seiko 7S26 and Orient F6922 movements). While adjusting the rate with a wooden dowel oriented parallel to the balance wheel, I have accidentally lightly grazed the hairspring. It was enough pressure to stop the balance wheel, but there appear to be no negative consequences. Both watches keep great time and have good positional accuracy. And according to my timegrapher the beat error and amplitude were not affected. So should I just chalk this up to good luck? Or could there be lurking damage I’m not seeing?
