Can you see any movement ID number under the balance? I don't see one but the picture is not very large.

It appears to me to be an old pocket watch movement. Interesting that the barell cover has been left off.

Find calibers longines made in www.julesborel.com site.

Longines also acquisitioned Rotory, branded some of their calibers and put them in Longines watches.

Well, I very highly doubt you will find a balance complete for that movement.

Replacing a hairspring requires vibrating it, which I don't even fully understand at this point.

You are looking at a high-level repair, from what I know, which will require experience and expertise to be done correctly.

Okay this seems like a job way too big for me! I feel confident replacing complete balances but the springs themselves... not even gonna attempt it! Thankyou so much for your help in this watch and I’m sure you’ll hear from me soon again. Appreciate it guys

I think a movement that fits could be found; however, it will not be skeletonized. Probably won't be Longines branded either, but you never know.

I wonder if this watch was put together and the process of cutting the plates up to open them caused the demise of the hairspring...

Not really too high- level , I do the vibrating right inside the watch, the hard part is finding a compatible hairspring. If you have one to vibrate I work with you and we can make a walkthrough out of it.

It would be great to get this watch fixed as it’s for a friend who was handed it down from a late relative. I’m not sure what’s happened to it it just come to me for a repair and with a missing hairspring

Sorry for the minor derail...

I want to learn about vibrating a hairspring but not in someone else’s thread. I had started a search earlier this week and was distracted by something shiny.

Hairspring distruction is a popular art and the true subject of this thread.

 No need for expensive vibrating tool as the watch itself is our vibrating tool.

I was surprised by your words that you" don't fully understand" and you will be surprised to see how easy the concept is.

I am sure the thread will be helpful to all interested in vibrating and building a balance complete.

Regards joe

      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.
