Looked it up on Google--Reminds me of Girard Perregaux and definitely looks like a front-loader. Remove the bezel by placing a very thin blade or similar ( I use a scalpel, but not everyone might have that) pop off bezel. You don't need to remove the crystal. The watch should then come out when you turn it over.

forgive my ignorance ,but what bezel?

The bezel is the metal ring that sits on top of the watchcase and holds the crystal. In your picture it is the portion outlined in yellow. The red line is where you should fit a razor or some suitably thin and sturdy object to pry the bezel/crystal away from the case. It should lift fairly easily, and it will be a quick matter to get it off once it does.

      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.
