  1. 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.
  2. 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
  3. 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
  4. 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
  5. 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
  6. 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-handl
  7. 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 th
  8. 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 ar
  9. 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!
  10. 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 c
  11. 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 hair
  12. 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
  13. 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
  14. 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!
  15. 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 twe
  16. 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:
  17. 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
  18. 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.
  19. 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?
  20. First, thank you all for your help. I’ve been reading several posts that have helped me since I first joined several weeks ago. I’ve been very fortunately the last year or so learning watch repair as a hobby. It’s been very rewarding and fun (as all of you know :P) A few months ago, I drunk bid, and won, this Zodiac Seawolf on eBay. It was supposedly running and then stopping after a short while (which was true). However, during disassembly I found it was missing the case tabs, hacking/stop lever, and most of the date mechanism parts. I was able to get it appart, cleaned, and luckily
  21. Here's picture of a WWII vintage chronograph I obtained c.1975. I think I paid $35 for it then--certainly less than $50. I actually wore it as a daily watch for many years. Then it started to run erratically so I put it in a drawer and let it "sleep" for about 10 years. In the late 90's I took it to a watchmaker in Chicago who said it could be restored, but it would cost! Even then something inside me--akin to a doctor's impulse to heal--wanted this watch to live. Besides, it has a nice rose gold case with the inscription "To Sid from Hank 1945 - 1946" on the back. So I let him do the w
  22. Another excellent video produced by the Litiz Watch Technicum on adjusting a hairspring correctly. Very video on their YT Channel is worth watching, and this latest one is no exception. https://www.youtube.com/watch?v=4EYk787sjAM
  23. I have uploaded a second vid on Hairspring manipulation - this time the hairspring is twisted up and down. View here!
