    Balance wheel stopped

    I was regulating my seiko 5, as it was running slow. As I was regulating it, the balance wheel stopped. I think I may have touched it by accident or something, since then it ran +150 sec a day but with no other problems. Should I be concerned about potential damage or is the speed just down to bad regulating?

    It’s a Seiko 5. It’s probably fine. Those adjustment levers are SUPER sensitive so you probably just overshot your mark.

    If it is now running +150 seconds per day that is big. Sounds like a screwdriver or whatever you used to move the regulator got into and stopped the balance and possibly damaged the hair spring. Hard to tell from the internet.

    edit: You may want to have a watch repair shop look at it and try regulating it.

    Verify that you didn't get any debris stuck around the area. Good chance you touched the hairspring. Likely gonna need a new balance wheel assembly.
