Identifying a mystery part

[Rafael 14]

Hi,

Maybe you could help me identify this part. I think it fell out of a vintage Omega Geneva case (maybe the back case) but I'm not sure as it seems to not have any purpose there + didn't notice it before but maybe it was jammed inside. 

 

Thanks in advance,

Rafael

we really need the back of the watch case but it looks like a ring used to hold movements in.

Thanks John. Here's a picture of the case back.

If a back case ring is a thing so it makes sense and it fit. It appeared of my work bench when I dropped the case back. Didn't notice it before, strange.

Hi  I have come across a similar ring under a rotating bezel to provide tension, the wavey washer/ring

That presses against the movement ring to hold it steady. No case clamps on these.

I was kinda hoping for the entire back of the watch case itself. But the case back was nice because we get a number from the number we get a picture.

Thanks guys! Much appreciated. 

Now to sort out the remaining issues. This Omega (which belonged to my grandfather) gives me quite a fight. Everytime I figure something out, another problem pops out
