Help with Lower Jewel fitting

I am working on a Illinois 12S Aristocrat pocket watch and the previous maintainer simply dropped a jewel in the pocket for the lower balance jewel; resting on the jewel end cap. I think the plate requires a friction fit jewel setting with the cap jewel, so I found a setting that sort of fits with a jewel that is the right hole size. So should I just go ahead and press in this setting? Anyone experience this situation before. I did not think that there were pressed in lower Balance jewel settings. My watch is the third model.42a7dd060f322825cf6b91a6eabaf79a.jpg1f951b80270f81354efc0fb96c6c5a40.jpg76fb62ec64573dee995f53fe2e8741d5.jpge6926e4dbbe89fa3d5a7b63ee85463cd.jpgNot presses in yet.3ea2007563cc7a4016aa69c983c1e9c7.jpg

the lower  jewel in some vintages elgin pocket watch balance staffs  have caused a problem for me.   one experence;   bought a watch that appeared to have a broken balance staff,  on dissassembly,  the staff was in tact with the lower jewel pushed out.   this could have hapened when the former owner pushed the jewel down when fitting the balance cock.?  vin

Was it friction fit in place? This one appears to be a friction fit, even from the data I included.

I think the proper place for this would be in "watch repair questions and advice".

Anytime were working with American pocket watches it's nice to have the serial number especially when looking for parts. Then because this is not your normal 12 size it's extra thin looks like you're right it's a friction jewel setting.  So image extracted from a listing so we get the diameter and the thickness. Then the other minor problem with Illinois all the different part numbers to make for a confusing mess.

Thanks for the data. Friction fit is odd.

      Just a note for those who come searching for information on this topic in the future.  I did eventually find the Mark's video on how to replace these springs, as someone observed, he does in fact make the replacement look easy.  (It actually is relatively easy once you have the knack of it.) If you're enrolled in one of Mark's online courses, the demonstration of how to replace this spring is in the Bonus Videos section of his course site, and is called "C2B1 – Sea-Gull Style Shock Springs".

      If the metal was twice as thick, it wouldn't snap so easily.  The thickness is governed by the space available so you can't use thicker metal.  If you glued two pieces together, the likelihood of snapping would be reduced.  That's my theory anyway, could be wrong.

      there are various approaches to learning watch repair. A lot of people want to jump right in and every single watches something to be repaired restored. But other times like this it's disposable it's here for you to learn and when you're through learning you throw it away. yes you definitely should try this you have a learning movement you need to learn and the best way to learn is by doing something.

      Sorry, the friction will be so great that the wheel will barely turn, if the movement will start at all, the amplitude will be verry lo.

      If I can’t re-pivot the wheel, the logical thing to do is to descend the pivot hole.  Plan is to either stick a suitably sized hole jewel (from a barrel bridge or something) or fashion a blob of epoxy on the underside of the escape wheel cock so the wheel sits on its one pivot on the base plate and the staff with the broken off pivot (which I’ll polish as best as I can) becomes the upper pivot. As long as it doesn’t foul the 4th wheel it should work? I know it’s a bodge job, and if this were a rare movement, or belonged to someone else I would not do this. I’m just interested to see if I can get the thing to run.
