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!
I finally got around to getting the NH36 movement and changed out the day wheel. When I put on the dial and was turning the crown to establish the 12 o'clock position to install the hands, I noticed that no matter how much I turned the crown, it would not change over. Did I screw up something? I was turning clockwise like my other 7S26 Seiko.
The Spiedel wasn't really doing it for me, so I popped it on a plain leather band, somewhere between rosewood and burgundy.
Much more appropriate I think, and a sight more comfortable I might add. I was almost tempted to post it in "Watch of Today" again, since I'm still wearing it. Not a single issue so far, and hovering somewhere less than +20s/day aver the last couple of days.
I figured it out. I totally overlooked that this particular 974 has the little blue locking screw to lock it in the winding position when out of the case which explains why the hands wouldn't move. I didn't have it locked which kept it in the setting position when out of the case and thus not having enough power to turn the hands....I'm an idiot
I think this is possible if there is very low friction to the cannon pinion. The balance and the trainwheels run but the cannon pinion and all following wheels and the hands do not as one of these parts is stuck somehow.
I would try and analyze step by step. Take of dial, hands, hour wheel and intermediate wheel, put the minute hand on the cannon pinion and observe.
If the minute hand does not stop at 12.05 take the next step and add the intermediate wheel and observe. After that add the hour wheel and so on until you find the step where the error occurs.
