  1. Hi guys, If You ask me, the best option is always to make a new staff on the lathe. In old watches, one can never be sure that no changes were made to balance parts in previous repairs, and it is never clear if an original staff will fit. Well, all depends on skills with the lathe, but with the practice, the skills will come.
  2. Hi Bob, The first I have to say is that You missunderstand the aim of escapement parts. If the pendulim is suspended on knife bearings, why in the world is that suspension spring there??? The suspension spring is needed to avoid friction in pendulum suspension. But the engagement between pendulum and palet MUST be hard, not via spring!!! If You ask me, this type of pendulum suspension will last no long, as the knifes will cut easy in the printed bearings... Make the bearings of steel an harden them, also harden the knifes too. Throw away the spring and replace it by rigid piece... Or
  3. I can say for sure only that the floating balance escapement was introduced first in 1956 by Smiths. So the 46 stamp will be no more than the personal number of the packing worker...
  4. Yes, the movement inside the clock is Hermle 340-020. They still produce and supply this movement. The clock manufacturer is hadr to find out, may be looking online pictures may help. The case design I think is from 70's...
  5. The bulge itself is not a problem at all. It is only a consiquence of mainspring break in the past. If now the mainspring can be winded to the end, then it is attached to the barrel and no reason to think that there is a problem there. BUT , if the mainspring has been broken once, I would check if it has been 'repaired' and in the barrel is only a short piece of it for example, or if the mainspring in the barrel is proper for the movement at all...
  6. Hi Jess, Show us a picture of the movement, measure it's diam. and height. Then You will have the answer.
  7. Hi Dilly, I must disagree with two other opinions above. By only replacing the spring/barrel, the clock will probably run for 3-4 days instead for 2-3 with the old spring…. See, if a clock or watch is running, this still doesn’t mean that it is in good order. The same if a man is breathing, this will not mean that he is in good health. If a clock movement is in a good condition and with new strong mainspring, then the amplitude of balance oscillations will be more than 250 degr. If the mainspring is old and weaker, then the amplitude will be probably 180 degr. , bu
  8. Hi Morthin, Looks like there is no connection with the hammer spring. Probably the striking part of the movement is not assembled correctly. The gears should be engaged in certain position against each other when assembling, so when striking stops, the hammer should be just fallen down. In "preparation" stage, the hammer should stil stay down, or just only a little lifting is acceptable.
  9. Hi all, No, this is a Kienzle movement from 1930's Here is a picture of another one with maker's mark on it...
  10. Hi Eagledale, This is late Roskopf watch, may be produced 1920-30’s. Roskopf watches were originally produced to be cheap but reliable, the workman’s watch. After Roskopf’s death, around 1900, almost any watch company in La Chaux de Fonds was making money producing a “Roskopf watch”, further simplifying the design and making it more and more cheaper. The result is what You have… It is ugly and cheap, but still able to work for several years. Don’t mint the “Railroad Timekeeper”, it is only a name. The same if You buy “Squirrel” pralines: You don’t expect to find a real squirr
  11. I can say for sure that this is a swiss cylindre movement. Usually there is no maker's mark on this movements, and shape of bridges is very common for the period, so no chance to determine movement maker.
  12. Hi Colin, The slots in the nut are something normal. The nut is only for fine adjustment of the pendulum length. There is no pressure or force there. Once it is adjusted, no more touching and turning is needed, so it is very strange that the thread is worn. Is it possible that the nut has been replaced with one with bigger size of thread? If now the nut stays in place and needs some force to be rotated, You don’t have to worry about it – all is perfect.
  13. I a sorry, I am pritty sure that it will not work.
  14. Probably the 3-hour period is connected with one full revolution of the chain wheel. Check if there is a bent tooth on it...
