  1. Hi gents. My hairspring was messed up and entangled. I tried straightening it up, but it didn't turn out perfect, so for 20 Euros shipped I ordered a new one. I have the balance cock ready, I lay the balance wheel and notice the impulse pin is way off. It's facing "backwards" (see below photo). How to put it in the correct position. And, most importantly, how can I check if it's perfectly centered and facing the pallet fork? Thanks for your wisdom!
  2. Hi, I'm at my wits end with this watch and can't seem to figure out what to do. I was hoping someone more qualified might be able to provide some assistance. I've been working on a Guba 1050 movement that had issues keeping a good rate in vertical positions and noticed that the hairspring was slightly bent. It looked like it was squished to one side at rest while the opposite side was slightly stretched out. I was able to bend out these differences until the hairspring looked concentric but upon putting the balance back, the hairspring was out of flat and slightly conical. I also noticed that the inner hairspring was touching the regulator pins when installed on the balance cock making it seem like the spring had too large of a diameter. I then removed the hairspring from the balance entirely to check the shape again in more detail but I can't find any issues. The hairspring is completely flat on my workspace and concentric as before. Any advice on how to proceed? Thank you in advance!
  3. Hi folks, I am working on my second restoration, a really beat up Waltham A-11 (6/0 '42 movement). I've gotten the easier stuff cleaned and assessed and now I find myself staring down the balance and hairspring for cleaning and realizing that I'm not sure if the hairspring is even viable. Here's the stuff I'm hoping wiser, more experienced hands can help me with. 1. I was reading about some hairsprings having a Breguet coil - looking at the parts list for this watch, part # 26218 is listed as Balance, Complete D. R. Breguet. Is that indicative that this watch should have one? 2. If it should have the Breguet coil, does this look like it's intact? I couldn't find any good reference images for what it should look like. 3. I circled two spots (labelled A and B) in the first image. Are these areas where bends should be? I'm thinking A is damage and B is part of what a Breguet coil would look like? Curious to hear what more experienced eyes think. 4. Looking at the balance staff, it looks like maybe the bottom pivot is slightly bent? If so, is it bent enough that it would cause issues? Can pivots be straightened and if so, what kind of tool is suggested? 5. How the heck does the block at the end of the hairspring attach to the balance cock? I unscrewed it fine, but I can't figure out how it would reattach. The first watch I fixed was an AS 1187, the hairspring nub(what is this block called?) just slotted in and tightened, but I don't see how the mechanism would work here. Final image is of the underside of the balance cock. 6. Last question - I have an ultrasonic cleaner, tons of 99% IPA and warm soapy water. My understanding on a watch this old was not to put the hairspring or pallet fork in IPA as it could dissolve the shellac on the jewels. I don't yet have access to OneDip yet, are there safe alternatives to use? I'm in Canada, if that matters. I've read a lot of threads with folks saying they use lighter fluid, is that actually safe? So far, this watch is getting the following replaced: Mainspring (old - blue steel with a decent amount of corrosion present) Barrel arbor (hook is gone) Hack (broken) Escape wheel (broken pinion) Click spring (was entirely missing when the watch arrived) Crystal (the original one is comically yellow and spiderwebbed with cracks) It's been a fun journey so far, I'm really enjoying the slow, intentional work and care needed to do this properly. Thanks in advance for any help or advice you can share.
  4. Where would one even start with this mess? Trying to put the balance in after cleaning everything, one small slip, and in less than a second: disaster. Comes from not having 100% focus at the end of a day I guess. "No Excuse Sir!"
  5. Hi All, I'm relatively new to watchmaking. Having serviced a few watches already, but I so far dodged more involved repairs. I was working on a nice Vostok watch. I have disassembled, cleaned, reassembled and lubricated the movement. One of the last steps were to reseat the balance complete. The balance didn't want to move freely so I had to take out and put it back a few times. I could have been too hard with the part or maybe the hairspring wasn't connected well enough. All in all, the hairspring got disconnected from the balance cock. My main problem now is that I don't recognize the substance/adhesive that the hairspring was connected with originally. It's a relatively tidy job so I think it was done in the factory but it's not shellac. I don't know if this can be warmed up so I can offer back the hairspring or should it be removed and replaced with an equivalent adhesive substance. The hairspring is OK as far as I can tell. Please kindly help me formulate a repair plan for this part. I would like to repair this part myself. I can easily source a replacement balance complete but I would like to learn how to deal with this. And now the pictures.
  6. Hello everyone, I bought an omega with an 711 movement and managed to find the problem : the hairspring was twisted. So I bought another balance and while trying to fit it in the movement I pushed a bit too hard on the tweezers and it made a 180 Flip (upside down). This tiny little accident made a “knot” in the hairspring, does anyone know if there is a way to fix it ? Thank you very much and sorry for my frenglish Louis
  7. I am correcting a deformed hairspring and need to set the curve for the regulator pins. De Carle mentions using curve-forming tweezers, which I cannot yet find. What are the alternate practices for forming this curved portion of the over curve? Thanks, RMD
  8. I have purchased a GUB09207211 hairspring from Cousins watch parts and I am not sure how to attached it to the anchor on the balance cock. Is there a tool I should use or is there a method that I can employ. Any help is appreciated Thanks.
  9. Hi everyone, I have some problems with a manual winding watch. It needs some work but I would try to do it myself. The watch appears fully wound but it doesn't work. Which is the problem? Thank you in advance Alessandro
  10. Hi all, 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. Thanks, Marc
  11. I work a lot on small caliber (ladies watch size) movements but still have mishaps with the balance hairspring. These hairsprings are very fragile and easily bent and removing/replacing the balance assembly seems to be my problem. I would like any comments on the risks of deforming the hairspring by allowing the wheel to dangle during handling. I would also like to know if the position of the regulator arm/pins has any effect re risk of deforming the spring, should it be close to the stud or as far a possible from the stud, I normally leave it where I find it so the timing is close to what it was before dis-assembly. Any advice on techniques etc will be much appreciated.
  12. While disassembling a Unitas 6497 (or during subsequent reassembly) I slightly deformed the hairspring, and to fix it I removed the wheel from the balance cock and then the hairspring from the wheel. The balance cock is of the Etachron type, so the index pin is simply clipped into the stud support. The spring sits inside a notch on the underside of the pin, and is secured in place with some sort of gummy, flexible adhesive (instead of a tiny pin, as I've seen elsewhere). Anyway, I had a lot of trouble getting the spring stud back into the stud support, and after about an hour of man-handling the glue finally gave out and the spring came loose. Now I have a spring (in perfect condition, thank you very much!) and stud I need to reattach to each other. What kind of adhesive is this? What are some accepted ways of reattaching the spring? I saw someone on the internet use shellac, but 1) I don't think that was the correct thing to do (this stuff was flexible, and probably for a reason) and 2) I don't have shellac or know how to use it regardless. Thanks for reading, and thanks for any help you can offer! Here are some pictures to help visualize what I'm talking about:
  13. Question for those who work on Vintage Timex watches: I've restored several Timex pieces from the late '60s to the late '70s. The technique I learned (from Internet posts and tutorials) say to simply loosen the dial-side balance pivot by unscrewing it 1/2 turn prior to cleaning the entire movement in an ultrasonic cleaner. This method contradicts the official Timex service manuals, which state that the balance should be removed, cleaned separately and reinstalled. Thus preventing the hairspring form being damaged in the ultrasonic cleaner. My experience is this: Leaving the balance in place (slightly loosened) is much easier and will work on the standard movements used in the '70s (M24/25, M32/33, M104, etc.) Attempting the same method on movements from the '50s and '60s (M22, M29, etc) will result in a kinked hairspring that is damn near impossible to un-kink. So my question is this: What do you experienced Timex restoration experts recommend? Leave the balance/hairspring in the movement for cleaning, or take it out to soak in a separate jar? Is the potential for hairspring damage greater when removing/reinstalling the balance - in comparison to leaving it in place? I've messed up a couple of vintage movements that I really wish I hadn't. I don't want to make those mistakes again. Thanks for any insights! -Todd
  14. Hi again all, since there are some really knowledgeable people here I hope you can impart some wisdom regarding repairing a bent hair spring. after getting this old movement working again with the help of this group (new mainspring), I need a little more advice. after hooking this beaut up to watch-a-scope it shows low amplitude and very erratic trace. I can see the hairspring is bent and need to start here in addressing the issue. What tools are needed (not willing to spend £50 on hairspring levers at the moment)? I have basic tools (enough to service a movement), but what are the essentials for working on a hairspring? i.e for removing from a balance safely what tweezers types/sizes are recommended for correction etc. Also, is there an easy way to identify and obtain replacement hairsprings? I assume they are very interchangeable as it would not have been easy to make new hairsprings for every watch model.
  15. 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!
  16. 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?
  17. Dear all, I recently had the pleasure of finding a damaged hairspring needing care. My first! It’s an inexpensive orient watch, gaining 20 minutes a day. I am taking Mark’s fault finding course, and have other inexpensive hairsprings to practise with. I also got some vintage tools I’d love to use. Until now for me levellers were only the Oliver Cromwell people, but ebay never ceases to surprise... I could pass the first stages of correcting the coil, with two tweezers. But could not find a use for the vintage tools. Could you help me to figure it out? Picture 1 is the bent hairspring picture 2 and 3 the box of tas levellers picture 4 is the hairspring suffering under my tweezers now picture 5 shows the tip of the tools picture 6: from De Carle. Would this be the purpose of the levellers? The overcoil?
  18. Hey, I'm on the lookout for a Hairpsring for a Hamilton cal 770. I've managed to find out that it's a Breguet made from Elinvar but that's about it. Does anybody know the parts number? If you also know where to get hold of one it would be very appreciated. Thanks! /A
  19. 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. George Corder IMG_0505.m4v
  20. 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!
  21. I have a few old Vostok 24xx movements which seem perfectly fine except the the hairsprings are ruined. Most of these movements have come from eBay sold as “for parts or service”. So, my plan is to buy a few new balance wheels complete with hairsprings (like these) and replace them. (I just haven't got the tools or skills to just replace the hairspring). I have a pretty good idea about how to remove the hairspring stud (like this, or is there a better/easier way?), but how do I remove and re-fit the hairspring from the regulator arm? Can it just be lifted off and re-fitted with a tweezers, or do I need some special tool or procedure for this operation? I haven’t seen any instructions or videos about this, perhaps because it’s so easy or obvious? Well, at least that’s what I’m hoping!
  22. Hello! So I was trying to work on the HS, like so I took a coaster from Ikea: and spare 1mm screwdriver blade and 2 pins: and I got:
  23. Help please anyone. Having trouble getting a hairspring for the Rolex calibre 59. FHF30/ 30-1 is the base model but I cant find any listings. Is there another movement spring that is the same? Peter
  24. Hello, I got this vintage medana pocket watch with MST 12 movement. When I opened them I saw broken hairspring. What should I do ? I´m very new to these watches, I need some help/advice.
  25. I think I have the kit to do this but how do I go about finding the right size staff to replace the broken one?
