  1. Wow, what a deep discussion this developed into ) Well, upon checking the operation in different positions, I discovered that ‘crown up’ the balance wheel started to gradually slow down, I could even hear the roller touching the main plate. When I ran down the mainspring, the balance wheel had a lot of side and up down movement. So the main suspect is here to blame, shortened of balance staff’s upper pivot. That on it’s own wouldn’t make the weird reading, but I think as the roller was hitting the main plate, it produced those extra ticks. I have completely disassembled the balance and ordered new staff from eBay (£8). To be honest the hair spring has seen better days, but it is centred and doesn’t stick. I made some pics so you can have a look, will post to this thread when the new part arrives. Thank you all for your input! Sent from my iPhone using Tapatalk
  2. Hairsping seems fine, but it may be bit old. I will check other positions, my main suspect is now the balance staff. The balance wheel seems to be doing some up and down movement, I am suspecting that the staff’s pinion is short or damaged. I slowed the balance down by moving the regulator as usual. What do you mean by ‘running timegrapher on monochrome’? It is Welshi 1900. Sent from my iPhone using Tapatalk
  3. Hi, I’m servicing vintage Venus 203 movement, triple calendar with moonphase, and on reassembly I get this reading: it is like 4 rows of the usual read... I demagnetise again and get the same reading, then I slow down the balance and now I see this: Any clue? Thanks.
  4. Thanks for the insight. Are there any usual problems which cause the movement to stop? At this point I am not sure what is the problem with my friend's watch, maybe it doesn't wind or it does wind but doesn't run...I will probably have a chance to take a look at it next week...
  5. Hello my friend wants me to look at his Jeager LeCoultre Reverso, mid-size ref. 252.8.86 Does anyone here know what movements did JLC put into these simple hand wound Reversos? And is there a way to shop for parts if something needs replacing? Are there any service sheets available? I won't be able to get my hands on it for some time so that is why I'm asking... Thanks for any help.
  6. The screwdrivers seem to be too big. This particular broken screw is 0.75mm and the smallest driver is 1.1mm http://www.moodytools.com/Moody_Tools_Screw_Extractor_and_Screwdriver.pdf
  7. Thanks you all for the various tips. I will try them
  8. Hi, I managed to brake a screw which is holding the movement in the case. Now, I don't really want to buy the dedicated Burgeon remover (~ £70), are there other ways to get it out? The screwhead went completely off so I am left with just the shaft of the screw deep inside the hole. I found these precision screw extraction drivers. Anyone has any experience with these? Are they small enough? https://eustore.ifixit.com/en/Tools/Drivers-Wrenches/Precision-Screw-Extractor-Set.html?cur=1&utm_source=google&utm_medium=mc&utm_campaign=gshopping&gclid=CjwKCAjw39reBRBJEiwAO1m0OaeDhACGsOqhgZnLzupVcHbStZSTnsmvOMKcmOgg7A1dAOpEmdIvCRoCoWwQAvD_BwE Thank you for any tips for other tools or techniques.
  9. I'm repairing in Cardiff... We may be in a simulated reality but I don't feel as a clone
  10. Sorry I am not from the US, what is Lititz? COuld you please post a link? Thanks.
  11. yes Elma. The basket mount is its standard of 64mm in diameter.
  12. Hello, I have recently bought an older ELMA watch cleaning machine which has a mounting prepared for the mesh basket module. Looking at Cousins or similar shops (even ebay), the brand new 64mm baskets+cage is quite expensive add-on, considering the bargain price of £128 for the whole machine. Now, is there a chance someone here has a spare basket? or do you think it is worth to wait and scan ebay for any old basket rather than buying the ~£100 new one? Thank you for any advice.
  13. Hi, I have recently bought this old Elma watch cleaning machine. It has the movement holder fitted and I do have a holder for the set of baskets, but I am missing the baskets. Any good idea where to find those? Obviously I don't want to pay ~150£ for Elma brand new... thanks,
  14. Yes the first one, hand detached from tube...
  15. Hi all, as I was servicing a chronograph movement Landeron 248, when removing the hands the chronograph seconds hand popped into two pieces (shaft and the hand). I was able to put the hand onto the shaft, but now the diameter of the shaft is a bit smaller so the hand slips and turnes on the shaft if I hold it in tweezers and blow air on it. What is the way to fix it? I do not have a staking set and I am thinking about broaches, but not sure if cutting or smoothing broaches would do the trick. Please help. Thanks.
