Another unexpected challenge on this Omega 710. The center wheel seems to be friction fit to a gear on the face side of the watch - some sort of odd cannon pinion arrangement I think.

See the red arrow in the pic below. What is the correct/safe procedure to remove this setup? I was thinking of using a Presto #3 tool (pic below). Thoughts??

Tried to translate some text from Swedish to English since most of my service sheets are in Swedish, but from the drawing you get a sense of how the floating motion works on these looks like.
I only worked on the older ones and lifted the small gear off with a couple of leavers, but it looks your wheel is of a different design. There is a jewel in between the wheels and if you lift the small wheel of the pinion on the center wheel should hold onto the mainplate and not press the jewel out.
But here is what one should expect according to my  the Omega sheets.

I would suggest putting the plate back on the backside before attempting to remove the canon pinion. That's because in attempting to remove it if you should twist in or lien at it might be possible chipper break the jewel. then I'm attaching some images you're supposed to use tweezers.

      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.

      A lathe with indexing that won't break the bank?

      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.
