Easiest approach to diagnosis is to remove the winder module, remove the two black screws and lift the module. Show picture.

Otherwise, 

Try winding through ratchet screw with a driver. 

Try releasing power by pushing winding wheel away from ratchet wheel.

Try turning the barrel with pegwood.

Report back your observations, if you will.

That looks like a ratchet wheel problem. Perhaps it disengaged from the barrel arbor. Other possibilities would be a broken Mainspring, although that would be less likely if this is a relatively new movement. You have to remove the automatic works to get a better look. I have a video on YouTube on regulating the ETA 2824 (The Sellita SW200 is a clone of the ETA 2824) in which I specifically demonstrate how to remove the automatic works. This will give you a better idea on what's going on. Good luck

      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.

      Help with repairing a quartz clock

      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.
