Help Removing Balance Bridge Jewel

I have been working on a vintage Omega Pocket Watch (from about 1916). It has a cracked balance bridge jewel. But I am unsure how to remove the cap jewel. I know the pivot jewel presses out but can't figure out the cap jewel. I have seen that on other brands they unscrewed from the bottom and the cap just came off. But the Omega after taking out the 2 cap screws that are on the top the cap doesn't budge and I don't want to force anything. See my photo marked "1".

Any thoughts on how to remove the cap? Any help is appreciated.

Thanks
Bob

It's probably "glued" in with years of accumulated vintage oils. Give it a good soak in WD40 or a penetrant oil and then ultrasonic for 10 minutes at about 40ºC.

That may clean/loosen up enough to get a blade under it.

You could use a stake just smaller than the hole to press out the chaton but you may sacrifice the cap jewel doing it that way.
The cock would need to be supported below around the cap jewel end piece.

You would press it out typically.

The answer to your problem. If you don’t have this tool, maybe find someone who has one. It’s a Seitz jewelling tool. You can’t do this work unless you have one!

I understand you press out the jewel itself but my question is about the cap itself not the jewel.

Again, you press it out.

Push them BOTH out from the under side of the cock. The bigger challenge will be to locate a suitable replacement jewel (or a suitable jewel in a suitable setting). Using the original chaton (setting), but replacing the hole jewel,in that setting will require the Seitz jewelling tool I showed, earlier. Appears you are beyond your depth!

If doing a jewel for the first time means I am beyond my depth, then yes. But I was aware of the Seitz tool and am working on access to one. Also aware of measuring the existing jewel with a micrometer once out and measuring the pivot. Also the potential for the need to shrink or broach the hole to fit the jewel. I already put in a new mainspring and did a complete cleaning and oiling. Just missed the cracked jewel.

Latest is I was just able to push out the original setting by hand without damage. It just popped out with some gentle hand pressure from a flat staking stump that was the exact size of the setting hole. I think I was just lucky there. Cap jewel is fine. Now I do need the right tools to do the rest.
Thanks
