  1. At “school” the staking of riveted staffs is highly discouraged. There are many ways to skin a cat and God knows that we’re always running into situations where we don’t have the specific tool to apply the optimal procedure and yet we end up sorting things out well. Even if the OP is beginning, it is important that he is aware of some of those basic procedures. His balance wheel may not be that valuable that he can experiment and learn even if it means that he will have to replace it... or he will be thankful to know that not everyone recommends staking it off, especially without any prior experience. He would then send it somewhere just to get staff off and move on with his repair. I would tone things here way down. This is a place for everyone to chime in even for those of us with less experience than others. I’m delighted to invest my time trying to sort things out with anyone open minded and appreciative. Won’t spend a second with anyone that rides a high horse and is there just pointing out how wrong we are. Cheers it’s Friday! [emoji482] Sent from my iPhone using Tapatalk
  2. I’ve been up to my neck in work but I’ll try to explain myself better soon. I don’t see an issue with oiling and such and thaw that you mention a weaker mainspring it does seem to me that that’s why your hairspring and balance wheel need readjusting or conversely try to find a closer to original mainspring. Cheers it’s Friday! Quick other thought: the time machine has limitations as to how far off range BE and rate can be displayed. You may be there. I’m not even looking at amp or BE... just the fact that you’re maxed out on your regulator and still too slow. Sent from my iPhone using Tapatalk
  3. The hairspring is not aligned with the balance wheel. You should remove the hairspring, and assemble the balance without the hairspring. Move the regulator to the middle position. Now you should slowly rotate the wheel until you find the dead point. Mark the spot on the wheel where the regulator is located at dead point. Remove the wheel and reinsert the hairspring with the stud right under your mark. Now that you put it all back together you’ll be able to regulate well. I hope this helps.

  4. Might as well use this extra post to show something!! Look how the arms fan out close to the rim. That’s a glucydur. Sent from my iPhone using Tapatalk
  5. Sorry triple post from Tapatalk! Sent from my iPhone using Tapatalk
  6. If in doubt, glucydur has the trumpeted arms. Quick google search will show you variations. That’s the highest quality wheel that you can punch on. Anything else, your wheel will get out of true in the flat. It’s great you’re working on it. Nothing better than guided experience. Sent from my iPhone using Tapatalk
  7. Depends on what type of balance wheel it is. Only with glucydur you can stake the staff off. Others run the great risk of damaging the balance wheel and then you need the whole thing replaced. Best to use a lathe to remove riveted staff and then the staking tool to place the new one. Good luck! Sent from my iPhone using Tapatalk
  8. Amplitude? Beat error? Deltas? How does the movement look? Does it start right away upon winding? So much info needed to make the call... Good luck! Great looking watch. Sent from my iPhone using Tapatalk
  9. Can’t comment specifically about 2801 but it does appear to be a proper etachron system. Sent from my iPhone using Tapatalk
  10. Looks good to me. I’d get it Sent from my iPhone using Tapatalk
  11. Looks good from 10,000 feet but I’d request a picture of the movement out of the case, especially the engraving with he ETA logo. Sent from my iPhone using Tapatalk
  12. How do you get this watch out of its case

    Interesting. It would seem that you’ll need to remove the dial and see what’s holding things? Definitively a front loader I’m curious to see what the right answer is. Sent from my iPhone using Tapatalk
  13. Automatic Movement Rotor Repair Fell Off!

    ^^^^ not to mention that precision or true in the flat and round it has to be to function properly. I certainly would experiment with it to learn but would be on he lookout for a replacement. Good luck! Sent from my iPhone using Tapatalk
  14. Automatic Movement Rotor Repair Fell Off!

    Please post a better picture. It seems the rotor came off the ball bearing. I recommend avoiding any glue whatsoever. Can you buy a replacement rotor? Sent from my iPhone using Tapatalk
  15. [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!
