  1. Hard to suggest without seeing what the problem is. Is the wheel stuck as in no endshake? Does it move a bit only to be stopped? Quick checkups of the train without the fork to make sure it spins freely. Then confirm fork movement. If all correct and down to the balance, I’ve found it very useful to separate the hairspring from the cock and install in the bare plate (no fork or train). Then you will be able to see what the problem is. A couple times I found that the endshake was killed after washing and pegging. Had to adjust one of the jewels and all was well. Good luck!

  2. The pics looks alright as far as I can tell. Tough with just one pic but I’d say it shouldn’t be doing that. given my own mishaps, I have to ask without meaning any offends... is it possible you placed the fork upside down and so the stones are not at the same level as the escape wheel and hence free spinning? Or is the escape wheel placed incorrectly? All teeth ok? keep us posted! Julian
  3. I’m no master, but I’m no butcher either. Hearing of these jaw-dropping (miss)procedures gives me a little pep in my step. Thank you for sharing and good luck! Julian Sent from my iPhone using Tapatalk
  4. I'm planning to enroll into the courses and bundling is the best way. My questions is that I see several videos marked as level 4 but I don't see a formal Level 4 as such. I'm not very interested in Level 1 so that if there was a Level 4 coming out soon I'd wait to bundle 2-4 or something like that. Anyone knows? Thank you! Julian
  5. The order of elements may be wrong. Can you show us a pic to better understand? Typically the crystal sits on the gasket. Sent from my iPhone using Tapatalk
  6. Thank you for your reply! I was able to get a proper part mainspring that fit properly and looks to me right on. I'm mainly troubleshooting the poor balance wheel function and fit and I wanted to start checking with the wheel train, which is where I'm a bit stock not able to determine if it's free enough to proceed downstream or if it's something I need to address before I move on.

  7. Hello again everyone, I got my hands on this wonderful Eberhard 38mm chrono that was sold as a Valjoux. It certainly looks like it on quick glance but then, for the life of me, I have not been able to identify which caliber. I've gone through pretty much all pictures of a couple databases of manual-wound valjoux chronos. It's in need of a service badly, but it still runs! All I can see under the balance wheel is a "96" which led me nowhere... Anyways, I figured I'd post a couple pics of it here and see if anyone can throw me a bone ;-) Thank you as always...
  8. Hello all, I'm servicing a CYMA 234 and have found a few gremlins. First the mainspring was jimmied badly and was slipping with minimal tension. Then, I found what I thought was a worn or broken staff. I was able to source one and realize that the pivots look just the same, therefore concluding that my initial assessment was wrong. Something nagged me to remove the pallet fork and put a little power in the mainspring and while the train gear spins "freely" at the very end it has somewhat of a sluggish end. This is a movement that I washed and oiled just a few days ago. So, I tried l
  9. Oh boy... jeweling is a complete topic or master skill in its own right. I’d say pretty advanced although it is straightforward. Jeweling tools are common anywhere watchmaking tools and parts are sold. Seitz made great sets. HOWEVER, nowadays there is the one and only Horia tool. This provides you with amazing precision to adjust the level of the jewel within the hole. After all, ENDSHAKE is what makes it breaks how a watch runs and the adjustments need be very precise. Anyway, the jewel hole is measured and a jewel 0.01mm bigger is chosen. You have to determine what kind o

  11. Thank you. Here a few more. There’s a T and 328 identifier under the balance. Sent from my iPhone using Tapatalk
  12. I have a vintage diver with a broken stem. I have been searching for quite some time for any reference about the movement. The closest I’ve got is that it may be interchangeable with a Seiko movement, but not sure what model. I don’t think it’s Unitas, it’s not in the bestfit encyclopedia. Not UTC either. Please post any info that could help me get out of the ditch. Thank you! Here’s a pic from the web: Sent from my iPhone using Tapatalk
  13. Have you considered joining a watchmaking school as faculty? Sent from my iPhone using Tapatalk
  14. UPDATE Excellent idea [email protected] Nylon beveled cast filed at spoke levels: Pressed case back And crystal was out without struggle Thank you very much [emoji1303][emoji1303][emoji1303] Sent from my iPhone using Tapatalk
  15. Totally agree. In fact it’s of a size I otherwise very rarely use so I may not have to replace it. I’ll try and report back. Sent from my iPhone using Tapatalk
