Hello, is it possible to take the wobble out of a balance wheel? I am working on a wyler as 1002 cal. And during the restaffing procedure trying to be very careful I managed to bend the balance wheel ever so slightly. I have a truing caliper and have been trying to get it out for over an hour. I have it down to a slightly better wobble than before. Can a watch operate with a mm of wobble? Am I using the right stump? Is there a video on this process?

Are you sure its the balance wheel that's bent and not that you have seated the staff incorrectly which will cause a wobble. Mark has a video of how to replace a broken balance staff.

Thanks for the reply oldhippy, after looking at it under 10x magnification I think that may be the issue not seated correctly. But to answer my second question, will I get a beat error with a slight wobble? My wheely is wobbling. Lol

I guess I answered my own question. I have been fiddlin with this truing caliper all day and finally figured it out. I managed to get the wobble out and it spends straight now. I went back and checked my other watches balance and They were straight, sigh

Well done if you have sorted it out the proof will be when its up and running and keeping good time. What you have achieved is a job for someone who would be taking an advanced course in watchmaking. :woohoo-jumping-smiley-emoticon:

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      By VWatchie · Posted

      Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.

      I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.

      Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.

      Broken watch stem in watch crown

      By Poljot · Posted

      If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
