Cyma Stem


Recommended Posts

I must be getting clumsy,  old (or both). I have broken 2 stems in a week. HSL very kindly sorted me an equivilant for an ETA movement. Now a nice little Cyma has suffered the same fate through me being careless. You know the type. Snap on back. movement comes out inserted in the back. Dial is flush with the edge of the case. Can''t lever dial for fear of damage so a finger nail under the crown usually free's up the movement. Not with this one. The stem broke like a carrot. An extension is not possible because there is no thread left on the business end of the stem. The usual suppliers tell me that its obsolete. Any ideas from anyone that might help me get a stem for a 486-2.

If you have a look for the Ronda winding stem replacement you should look for one called RONDA 1362, sometimes it's easier to get those.

cousinuk obviously says they are obselute but a romainian ebayer has them, bought some odd stuff from him before.

Thanks again HSL Your a lifesaver. Think I will use that link you gave me....I did find another website called Windingstems.com which might be useful in the future but a bit more expensive. Especially if I keep breaking 2 a week

    • Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!
    • Happy to have helped, great way to start the day with a win! 🥳
    • Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor. 
    • I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂
    • Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
