Is there a 'golden rule' relating to relocating a hairspring onto a balance staff with regards to getting zero beat error after it has been removed for attention. I usually take pics or use marker pen but sometime forget!
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?
I received a lys Longines 5L for cleaning. Upon opening the case, I saw some surprises under the balance bridge.
I have outlined my steps on how I uncoil a tangled hairspring in hopes that others can benefit by this method.
I’m a new member and new to this ‘hobby’. This site seems to be where it’s happening.
my very first attempt is with a BFG 866 which I have stripped cleaned and rebuilt. Not applied any oils or greases yet as I plan to do this a few times. However... I have noticed that the hairspring has come detached from the ‘cock’ plate? I cannot see nor find how this is reattached... is this broken?
Any guidance is much appreciated.
I need help with removing and then putting back in a hairspring that has a friction fit stud. I know there is a special tool one can use for this purpose. Does anyone have any pictures and know who might have made it? Can anyone "walk me through" how to remove and replace a hairspring without using the tool? Thanks!
You are sayin that the wheel isnt centered , then i would check that the wheel isnt made for being under tension from the side,that little piece of metal could have been Lost (piinged across the room)by the last intruder And not noticed.

Allya need is love... and perhaps a little lubrication... and maybe another 15 or so jewels.
This late '70s wonder joined my current favorite in the 404 club on my wrist this evening. As well as a good clean and some light lubrication it required a little gentle hairspring massage to flatten out a rather obviously bit of conical contortion.
Despite having more fingerprints in it when it arrived than jewels (at least three of the former and only two of the latter), its Hong Kong heart is now ticking along quite nicely.
Friction spring i think, i have bought a selection on eBay, cost next to nothing If and when you get it running I would like to know if im correct or it was something Else Another clue to the problem was your info that it runs nearby 3/4 and the next time Its something Else that indicates that the problem is in that direction If it was worn teeth the revolutionrate would be more the same and the date would stop entirely imo.

From looking at pictures I can find only one of them seem to have a different design that seem to center the disc better, from the looks of it the others don't have this. But, it would be logical since the disc isn't perfectly centered. Haven't been able to find out what this is called.
