  1. Welcome aboard bjd1020, and thank you for an excellent introductory post.
  2. Vine, take it up with Mark, you never know he may run with it.
  3. No argument here. It is Mark's forum and only he can make a decision regarding this matter.
  4. I'll have a go; 19th century Chinese.
  5. It's a valuable and complex piece, please take the advice above and instruct your customer to take it to a specialist. You could be in a world of expensive hurt if you go ahead and possibly damage it.
  6. Please do Richard, my very best wishes from Scotland.
  7. That's sad to hear. I have dealt with Larry on numerous occasions and found him to be an absolute gent. It doesn't sound too good, but I would like to publicly thank him for his excellent service over the years and wish him all the very best.
  8. I use one like this. https://www.ebay.co.uk/itm/2L-DIGITAL-STAINLESS-ULTRASONIC-CLEANER-ULTRA-SONIC-BATH-TIMER-HEATE-WITH-BASKET/123299753924?epid=27019408168&hash=item1cb53cefc4:g:Sw4AAOSwup1b0Y--
  9. Nothing wrong with your English! A great introduction and I wish you well with your new hobby. There are plenty of folk here that are both willing and able to help yo when required.
  10. I managed to pick up pretty much all that you have there JD, only not as a dedicated set. I really do like boxed sets of tools like that.
  11. Lovely set JD. Is it all complete?
  12. This has to be the biggest box for the smallest movement ever! Delivered this morning and couldn't believe it.
  13. Joe, I tried contacting him a couple of month ago but had no joy. If I remember correctly he did have health issues, so let's hope he's OK.
  14. I would suggest that you have it serviced. Do not put oil down the pendant tube, it will cause more problems than it solves as there is no saying where the oil will end up.
  15. You will see the tool I used to open the case in one of the posts.
  16. Have a look at this thread, it may help you.
  17. The shaft is located between the hollow centre of the driving wheel and the shoulder of the pivot at the jacot end. The driving dog sits between the the spokes of the wheel to impart the driving force. Nothing is clamped in place.
  18. I think you will be highly unlikely to pick up the correct tool for this, even on EBay. It's an easy tool to make accurately without machine tools. I too used an old set of steel tweezers ground to fit the nut tightly as I couldn't be bothered making the tool for a one off job. As OH says, you could make one using a suitable hollow punch from a staking set if you have a spare one,
  19. As you say, there are two sets of numbers on the gauge. I'm sure the left hand set of numbers is the diameter of the pivot in Dousiemes, and the right hand set is the appropriate Jacot drum notch that you should use when working with that pivot. To check this, measure the gap of the gauge at the relavent numbers and see if it corresponds with the sizes I have given. Here is a conversion of Dousiems to Millimetres. 1 = 0.19 2 = 0.38 3 = 0.56 4 = 0.75 5 = 0.94 6 = 1.13 7 = 1.32 8 = 1.50 9 = 1.69
  20. Excellent conversion, I do like quality innovation!
  21. Hi and welcome. Could you post a photo of your watch showing the dial, and if yo can open it the movement?
  22. I've used one for years with no detrimental effect to hairspring. Many professional watch cleaners also have ultrasonic cleaning.
