  1. Always putting the fork in one direction would mean awkward installation for some movements. On a 7750 it would be installed with the cock over the movement and rotated outwards if the pallet is set to the left for example. More intuitive way to do this without having to remember which direction to twist things for different movements would be to just flick the fork towards the inside if the movement and present the balance with cock pointed away from movement, then rotate it inward into position and fasten.
  2. Yeah what I thought you were saying is that they were powered by the minute wheel and not that they were aet through the minute wheel. The 7750 would not have been set through the minute wheel as the setting wheel engages the canon pinion directly. Back on topic: yeah it is of my opinion as well that it isnt a problem with the movement. Rather something went wrong with the attachment of the dial and allowed the hour wheel to lift up.
  3. It looks like rather the minute pinion tube not protruding enough, it is the hour wheel that's somehow lifted too high. Also the hour hand is way far down the tube than needed.
  4. Hmmm I haven't worked on too many movements but the only movement that has the minute/canon pinion driven by a minute wheel is the 7750. Everything else I'd seen have them driven by the barrel whether they be the center wheel or a separate pinion like in Rolex.
  5. Huh that would make it a very unusually shaped pallet. Can you photograph that part for us too?
  6. Huh... Very odd that a pivot jewel would have no hole for the pivot. Can you provide a picture of the situation? Could it be a capped jewel but with hole jewel missing?
  7. Done few of these myself. Favorite kind of collet to deal with. Just need an oiler and they come off without fuss. No need for razor blades levers or sweat. Unfortunately these don't seem to be in fashion these days. Really hope you find that video. It would really save me from any more sweat and tears haha.
  8. Haha you can count on that. Been tinkering with watches for maybe just a year. Lots to learn.
  9. Well the collets on these are like 4 leaved clovers with the hairspring I guess laser welded to one of the leafs. When I tried levering up one of these collets using these leafs they just snapped off.
  10. Can you share this solution with me? ETA collets are a bear to handle. I even had one crumble on me when trying to remove
  11. Oof glucydur balance. Not as easy to find as nickel. Haha that's similar to what I do sometimes. Quick and easy way to make sure the spring is in most relaxed state when mounted. As well as easier and more accurate to adjust should it need any. I use glowing hot kanthal wire from my vape mod haha.
  12. Yes I've realised the mistake after it was too late to edit.
  13. Looks like some sort of yoke spring. A yoke is usually a long piece that gets slotted in the slot on the sliding pinion. Usually there are 2 parts that the stem get threaded through. There flat one is the crown wheel and the cylindrical part is the sliding pinion. The yoke spring would push the sliding pinion towards the crown wheel through the yoke.
  14. Lift angle setting should have no bearing on timing changes. It's far more likely it's the watch itself that deviated, whether it be from magnetism, oil run in, temperature etc. Watches do deviate a bit in performance one day to the next. To make this test scientific you have to run a string of tests on different LA settings. Also I don't think a few degrees difference in LA setting gives near enough drastic impact on amplitude to affect our ability to find faults.
