A while back I made my own circlips/c-clips for some chronograph pushers out of music wire.
The results were OK, but now I'm needing some clips for a different watch with a much smaller groove for the clips.

I don't think I'll be able to make them by hand, and I haven't found anything small enough other than some M1.0 clips. These seem to be plated with something or have a black oxide coating. Probably not meant for watchmaking, but would this be OK to use?

Have you checked out what's available at Cousins?

Thanks for the reply. I did see those, but I'm unsure about how much wiggle room I have between the cutout in the case and the O.D. of the clip (it retracts back into a small hole). 

I suppose I could just order a full set or a few different sizes to test.

Put the clip on a small enough screw and chuck it in the dremel. Spin it against a Swiss pattern file, checking the OD as you go. 

You should be able to take a bit off. Give it a light smear with some silicone O ring lube (Molykote 111) to keep corrosion at bay.

Thanks, I will try that method when I have some time next week!

On the other watch, I documented this method to make the clips: https://www.watchuseek.com/threads/creating-a-chronograph-pusher-c-clip-how-did-i-do.5165357/

I thought it might be too small, but now I'm up for two challenges. ?
Just ordered some 0.008" music wire (0.2mm) to fit the smaller groove of this watch, so in reality it will be 1.40mm x 1.0mm x 0.2 mm

      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.
