Omega case ref. 2190 - am I really alone with this one?

I am new in this wonderfully exciting forum and newly in love with vintage Omega watches. I have recently purchased my first ever Omega, a 30T2 that turned out to be redialed (thank you for your advice and insight) but I was lucky enough to be able to exchange it in the shop for another 30T2 of the same price which seems to be (more) original (I really hope). It has a case ref. number 2190. As I was searching for more info on the net I arrived to the conclusion that this may be quite a rare case model, I found only 2 photos and mentions. I attach here first a photo of my watch then the two other photos of 2190s have found. The cases seem to be the same based on the photos. So it would be interesting to hear if anyone here has a 2190 watch and what it looks like...

My watch on 2 photos (with movement serial: 10 4..)



Another ref. 2190 I found, with movement serial 11 3...:

and this one with movement serial 10 3..

Guys, hard to beleive noone here has a 2190 except me... Next step is I show you the case to prove that this ref. exists 😀

Hey,
Happy to see that I'm not the only one looking for details on the 2190.
This is my grandfather's watch. It's also a 30T2 but slightly different in design. According to the serial it was manufactured in 1944.

The winding works like a charm and I'm really wondering if I should send it to Omega for restoration. I have no intention in selling it so I don't really care about any depreciation due to the restoration.

Thanks for your comment @lindo. It makes a lot of sense that dealing with the dial may do more harm than good. Perhaps I could get just the glass and the housing polished and cleaned.

Polishing or replacing (if feasible) the crystal is the first step, and there should be no need to send the watch to Omega for that. It can be amazing how much a clean, transparent crystal improves a watch's appearance.
