    How to remove stem from this JLC

    I got an hour before work today to set up the camera and take a look at the end curve of the balance. I can see slight movement, in the hair spring. What do you guys think? Is this enough to cause a significant issue? One other thing that happened is when I put the balance back in I gave it some turns of the crown very slowly and it seemed to be running nicely, not this strange idle I have been seeing. I didn't put the screw back in to fix the balance. I lifted the movement over to the timegrapher to check it out and something happened and was idling again.... anyway here is the video.. Youtube really does compress things so apologies for the quality original file is much better

    That’s a great video thanks. So first I need to check when moving the regulator the end coil doesn’t get caught up? This is where in the video he is moving it backwards and forwards making slight adjustments? Sent from my iPhone using Tapatalk

    Thanks for that John, lots for me to take in there. I’ll try what HSL suggested first if that doesn’t work out for me. I’ll try placing a small mark on the balance. I looked online and most images look pretty much exactly like mine, in some the rate is slightly more clockwise. I don’t want to detract too far away from this was working and has just sat in a holder with the occasional auto wind. I think it would be pretty hard for one of the corrector screws to be adjusted by accident. Sent from my iPhone using Tapatalk

    Duh, can’t believe I thought that rookie mistake. Getting too wrapped up in other things and forgetting the basics. So i adjust the + and - ? I’ve not seen this type before can I just adjust one without the other? How would you approach adjusting this? Sent from my iPhone using Tapatalk

    Surely if the watch is running at all the jewel must be inside the fork? I will try this again without concentrating on trying to see the impulse so much and focus my attention on the fork Sent from my iPhone using Tapatalk

    This is with the new (but needs a clean balance). Moving the regulator arm to both extremes did nothing to the beat error Sent from my iPhone using Tapatalk

    Hi John, thanks for your advice. So to do this I need to look straight down the pallet fork to the impulse jewel and check it’s lying directly in the middle? I’ve tried doing this under magnification and I can’t quite see the end of the pallet fork where it meets the jewel unfortunately Sent from my iPhone using Tapatalk

    Yes it does look different. Thanks for offering to help. @nickelsilver does this confirm your suspicions? I think I need to practice on some cheap Chinese 2824 movement first... Sent from my iPhone using Tapatalk

    Hi guys, Sorry for going quiet. I found another balance for sale so I ordered it. I thought I’d wait until it arrived before I asked anymore questions. Anyway I have it. It’s a bit old and could do with cleaning but I installed it in my movement and it works. I put the two side by side and took some images. Apologies for the focus, this microscope has a poor resolution monitor and the tiny d.o.f at this magnification can make it hit or miss. Looks like that jewel is slightly out of place other than that I can’t see anything. What do you guys think? Sent from my iPhone using Tapatalk

    Don’t worry, everything is on me. I take full responsibility for anything I do. I’m pretty good at this sort of thing, and usually get it right. I have to fully understand what the problem is and what I’m doing though and in this instance I do not, so will not be attempting anything just yet Sent from my iPhone using Tapatalk

    Yes definitely. I’d practice on another hairspring first. I’m still perplexed how this could happen without touching the movement.... Sent from my iPhone using Tapatalk

    In the picture above looking down at it does it need to turn anti-clockwise? Sent from my iPhone using Tapatalk

    So, I’m definitely out of my depth here but let’s see if I can learn. Do you mean this part highlighted in red (sorry for the dodgy arrow drawing with my finger on phone). How do I go about resolving this? Thank you guys for all your help Sent from my iPhone using Tapatalk

    Hi guys, I've got a little lost in the terminology, which part has turned 15/20 degrees?
