  1. There was no need to replace the spring. If You take it out, then You can reshape it in manner to aply more pressure and then return it in place. But most important here is to ensure that the rack moves easily and smooth and no hardened oil or rust are in the bearing to bother the movement. I am not sure if the new spring will fit without need of reshapening too...

  3. Folks, this is not at all an attempt to restore a pocket watch. This is miserable attempt to open a pocket watch, but I guess that it will be not a succsessfull one... This is something that I cant understand! Believe me, never bulgarian or russian will ask how to open this type of watch or how to dissassemble the movement. This has never happend! They will ask how to assemblle, how to turn new balance staff, how to cut a new wheel, how to repivot an arbour...
  4. This usually happens when one tryes to turn hands backwards. Anyway, there is a brass bushing with square hole in the minute hand. The easiest way to solve the problem is to turn the bushing against the hand in needed direction. Hold a square needle file in a vice, string the bushing on the file and force the hand to turn against the bushing.
  5. Just put a knife blade in the gap between case and back cover and press it, then turn it to lift the cover. Be carefull, not to cut Your fingers!!! No need of sharp knife, use one that You will no regret if get damaged... If it doesn't open, then press harder...
  6. The case is made of iron with nickel plating... Inside should be no jewels movement like Ingersoll or Kienzle...
  7. Please, don't try to exlain this to me, I restore antique watches from many years. To open this watch it will be as easy now as i was before, nothing has changed...
  8. This is a BIG mistake! The firsth thing to do WAS to get the movement out of the case and to examine it's condition. Yes, the case can be treated with rust remover, but this can be totally harmful to the movement, if it was in restorable condition...
  9. Yes, this could be a good project, but if You ask how to open it, it means You are very far from being ready for such a project... Just take a knife and press it and lift between rear cover and the case. There should be one more cover under the first. Then show a picture of the movement. Probably it is a cheap movement that is not worth to do enything for it, but who knows...
  10. Try this https://imgur.com/upload?beta drop the image and URL will appear. Copy the URL and paste it in the message...
  11. You can upload image whereewer and just paste the URL in the message. Oherwice, when writing message, a button "Insert image from URL" appears in down left corner of the text window
  12. Hi, If You can show a picture, it will be much easier...
  13. Why swiss movement in english case?? At that time no english movements were produced that could compete swiss mowements on price and qwality. So, swiss mowements totally replaced english... The patent is for negative type remontoir, which was used mostly in US. All swiss movements that were to be exported in US, should have this type remontoir. Probably J.W. Benson bought this kind of movements
  14. Hi, This is a typical Cyma-Tavannes movement http://www.ranfft.de/cgi-bin/bidfun-db.cgi?13&ranfft&&2uswk&Cyma_19_3
  15. Hi guys, This watches are a little bit different. They have balance bearings rather like in alarm clocks. Staff ends with sharp cones, not with cylindrical pivots. The cones lie in steel female cone cup bearings. This system is easy to produce, absolutely shock proof, and works very good. But, after 2-3-4 years of work, the top of cones will wear and friction forces will rice so much that the amplitude will decrease dramatically and watch will not work correctly and finally will stop… This kind of watches are not intended to be serviced, but rather to be thrown away when begin not to work properly, and replaced with new watches… The price of the watch was comparable with price of servicing of normal watch. Anyway, repair is possible, but one must learn how to sharpen the tips of the balance staff. The cup bearings wear too, but much more slowly than the staff. One will usually sharpen the staff 3-4 times before change or repair of the bearings is needed.
