  1. Hi all.. I recently purchased the above watch with 221 movement for my daughter. Everything works, but as expected it runs fast. Does anyone know of anyone in the UK that can sort this out? It's a lovely, clean example that should be worn (if it can tell the time) Thanks in advance
  2. darnit.... I'm all out of vintage Omegas... I've got a few patek philippes hanging about, you may need to settle for one of those haha. Yes, the Setting lever likes to 'drift' when attempting to locate the screw to the hole while at the same time screwing with screw head that loves to spit out the driver tip...an absolute delight. Apart from that, it's been a lovely movement to work on. my second movement, and quite enjoyable. waiting on a replacement balance complete, then i'll have a charming vintage piece to wear. Thanks again for your help
  3. You chaps are blinders, thank you!! Much appreciated! If I had a Christmas card list, you fellas would be on it
  4. thanks for your reply @aac58 According to the technical doc (attached) part 5443 - setting lever screw- is the correct screw... I can only assume someone has butchered this for some reason but I have no idea why... 2763_Felsa 690.pdf
  5. Thanks for looking... On a reassemble of this movement I noticed somthing I'd not noticed on dismantling. The date set lever screw hole seems to have been butchered at some point. It fouls on the weight as it rotates, I do recall the weight not being able to rotate when I received the movement but assumed this was down to muck and grime and assumed once things were cleaned and oiled there would be an improvement. Moving forward I can only think that the main plate will need drilling to ensure the screw can tighten into place correctly as I truly cannot think of any other reason or way to approach this. If anyone has ideas, I'm all ears
  6. Thanks @JohnR725 After careful studying of the spring in situ, every alteration I made just didn't address the issue and I began creating new issues. I have opted to obtain a balance complete which should hopefully be the end of that problem. although wile waiting for my new tweezers to arrive, I though to fully assemble the rest of the movement and ran into another snag. The oscillating weight in fouling on the setting lever screw when it rotates... I don't recall this occurring when i first obtained the piece, but I cannot see a way around the issue...
  7. I will soon be ordering some tweezers (on my next pay cheque) and have a 'bash'. Are there any tips on doing this while the spring is in situ? All of the videos I've seen remove the spring entirely... From what I can see, the terminal curve, while simple, seems very gradual in its arc with an ill defined starting point with no seemingly defined bend (other than the one leading to the stud). Should I attempt to correct the stud curve first?
  8. @JohnR725 Thanks for your time and explanation. I've identified the 2 probable areas that will need altering though I will analyse the spring with the regulator in different positions before starting, and as you suggest this should be done in situ. My dexterity is pretty good and as you say, given the worst outcome, there are replacement balance completes. I will need a good second pair of tweezers, I've heard brass is a good choice as it is a little softer than steel. I do not need to rush this as I wish to learn and rushing will not accomplish anything... other than another set of tweezers, is there anything else I should consider to make the job easier?
  9. @JohnR725 I've compiled some more information, mainly pictures to attempt to clarify the situation.... Some better images of the hairspring including the regulator pins (the spring appears to be seated correctly), however there is definitely a deformation of the spring in the termianl curve as you correctly pointed out. I think the spring is fouling on itself where the coils are tighter. I have attached an image of the graph from the felsa which indeed looks odd (though I did alter the regulator to see if positively or negatively affected the trace. Apparently, according to the graph, it had a negative affect as the software cannot find a consitant 'tick' now. I have also attached a raw data image from a AS2066 movement that I have yet to work on (just to show the reliability of the setup). I do have some scrap slava 2428 movements that i used to source parts fo the 2427 I renovated. I could use these to practice manipulating hair springs. I have found some balance completes for this movement (watch also shares parts with the felsa 1560). forseably, if i do make a mess, replacments are available (though I would like to avoid that if possible. I have seen the video you posted, and watching the beat alter with the deformed terminal curve is the reason I was asking about mainspring manipulation in my OP. What are your thoughts? Should I be looking elsewhere?
  10. Thanks for taking an interest John, This is my second watch, I am new to watch repair, my first was a slava 2427. I have no baseline data for this watch as the mainspring, second sweep pinion and crystal were broken. It was sold as a non runner. I have replaced all broke parts and now have life in the watch but as you can see in the vid, the hairspring is compressed on one side (the spirals are not concentric. I can see the spring is deformed at the regulator and this is where I'm guessing there is a problem (though admittedly there may be other issues but I'm unsure of any others until I've sorted the hairspring out. I'm unable to slow down the vid bit I don't think the watch o scope trace will be of any help until the spring is corrected/replaced (though I have attached it in case it can provide any clues. just to note, I was curious, as the only way to set the beat is through adjusting at the collet I thought I'd have a look, I made a slight adjustment as the impulsed jewel was not within the banking pins. My adjustment was as improvement but still I don't fell that is there is a beat error, That it is significant at this time due to the larger issue of the hair spring (and what ever else may be going on.). Thanks for your continued input
  11. Thanks for your information, the collet is movable, as i noticed the balance jewel wasn't within the banking pins when at rest... i made a slight alteration using my smallest driver and that helped with the alignment, but not the erratic trace. After John's reply above, I think I'll attempt a dismantle and just look at the condition of the hairspring... I'll post a pic and get some thoughts.
  12. Thank you for the heads up on that one... at least i can direct my search if it all goes pete tong.. I've found some (not cheap) but the the spring is non functional any way so if i balls it up, no loss..
  13. 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.
  14. Thank you for all your input, I actually cannot believe that I seem to have lucked out and found a suitable length part... My relief is huge!!! However, after tempting to oil the lower the balance I have now lost an end stone to the god of the nether world... I am now hunting... for some reason the when i fitted the balance the whole thing just started galloping... I mean it would have run a whole day in a couple of hours... i assumed I hadn't positioned the balance correctly and so started looking.. now I'm 1 cap jewel short...
  15. Oh.. If I a) had a lathe and b) knew how to use one I would definitely do this... Looks like I'll have to put the watch away for another time... Shame I was really looking forward to wearing this one..
