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 clearly know your stuff mate, and amazing quality photos... I just put them on my Tab 4 and will follow your pictorial while trying to disassemble a 2836 bought for practicing.
Thanks for sharing, sharing knowledge is what makes WRT such a great forum
