How to repair/disassemble this balance bridge jewel setting?

[szbalogh]

Received a similar to Ruhla wrist watch for repair. The owner gave me ~thousand balance staffs and a box full of parts of different manufacturers. Inc. some Ronda quartz movements.

The watch has two issues. Both balance staffs broken and the jewels in the balance bridge are cracked shards. This is a low end watch with 4 jewels. I dont know how to disassemble this balance jewel setting. But i have noticed two notches on the top of the setting next to the cap jewel. Is this setting maybe a screw-out setting?

Looks like a press-fit setting. You would need to use a jewel pusher from the underside (same side the balance is on).

To be clear - the pusher is used on the brass fitting - not the jewel. The jewel and chaton come out together. Replacing the jewel in the chaton itself is another matter. It may be rubbed in (that may be what those notches are from) - hard to see for certain.

I snowed in on Quartz movement and thought it was a electronic movement?  But that is was not  That is a Ruhla UMF 24 pin lever movement.

As i remember the mainplate and dial side is different, i will post a picture of that as well. The jewel setting is also different.
