  1. [emoji848] I think I need more info. Is it that with the cock screwed down you have a gap between both pivots?? And you have to drive the pivots into the jewels to engage them? That would be a bad endshake situation and before bending cocks I’d adjust jewels. On the other hand, I can’t make much out of the pic, but it don’t seem right to me...is the jewel opening deformed and that’s why the pivot doesn’t engage? Is it a capped jewel? Cheers!

  2. Particles on Rolex dial

    Great thought but I can’t see the movement being powerful enough to push through causing such debris. I’d expect it to stop, or at the very least speed up significantly while losing amplitude. May be a good idea to put on timing machine and see what it does. Cheers Sent from my iPhone using Tapatalk

    Wow [emoji54] - that’s a lot of debris. I can’t imagine it’s from the seal but I’m super curious to hear what others think. Sent from my iPhone using Tapatalk
  4. Subtle timegraph issues?

  5. Subtle timegraph issues?

    May be the case but there’s not tons of info on sound wave analysis. I’ll leave it to more experienced guys to comment. I’d stick to the standard rate, BE and amplitude on a few positions. I would go chasing the sound waveform if all else looks fine. Of course, just MHO. Cheers! Sent from my iPhone using Tapatalk
  6. Nice! You’re on to something. Sometimes opening the barrel to clean the mainspring will change the endshake so that when you put it back on he bridge it’s caught. I bet that the arbor has a good endshake but the actual barrel rubs on the bridge. I suggest you remove the barrel and look at the arbor shake within it and then look at the lid of the barrel to see if it’s bent outwards. Cheers! Sent from my iPhone using Tapatalk
  7. Good morning. My suggestion is to power down completely and to remove the balance wheel and pallet fork. Now turn the barrel slowly and if you truly don’t have issues with the train wheel the escape wheel should start spinning rapidly. It shouldn’t take more than half a barrel turn. Caution as too much power can damage the wheels badly. If it doesn’t turn, then you have to find what’s wrong on this side of the movement. If it does spin freely than it’s either the pallet fork or the balance wheel. Good luck and keep us posted [emoji1303] Sent from my iPhone using Tapatalk
  8. Vintage tool's or not?

    Calipers, canon pinion remover, plexy and brass(?) sticks, micrometers... not sure of the rest. I may be interested. Sent from my iPhone using Tapatalk
  9. Movement Ultra-sonic cleaning

    Hello, I’m chipping in not as a seasoned watchmaker but as one on my way towards getting there, accumulating experiences and slowly building up a decent shop. Like anything else, every step of the way can done differently and how much funds and effort you put into is is what you get in results. There are many US machines of various qualities from $30 to $5000 and more. The cleaning liquids are also important. I’ve heard more negatives han positives about lighting fluid leaving a coat behind. So, yes, an US cleaner will improve on your hand washing process but it will remain inferior to the standard automatic washing machines what incorporate US features to the process. I’m a believer in pre-cleaning with the movement assembled then reassembling, full wash, peg’ing and reassemble. Keep it going!!!! Cheers! Sent from my iPhone using Tapatalk
  10. Cleaning the dial

    Hello! I believe that is degraded lacquer from the dial itself. Removing it even carefully will likely leave a clear mark. I’ve learned the hard way. The dial itself is not bad at all and a new crystal will make it look more like desirable patina. Hands and markers looks very good! [emoji1303] Please keep us posted.

  12. Mainspring winder for Seiko 7S26

    I’ve found that for some Seiko mainspring it’s best to use a combination of one handle and another drum. The appropriate size drum has too wide of a post. Anyway, my 2 cents. May just have to do it by hand... Sent from my iPhone using Tapatalk
  13. I can't remove this last wheel!

    £70 may be better than crimping the pinion while trying to pull it off and then having to either buy another one if still available or spend some effort in restoring it. Good luck! Sent from my iPhone using Tapatalk
