Any help to identify this vintage manual wind gold omega 40s?

Hi!
I have recently bought a vintage 18ct gold Omega watch for my husband's birthday.
I know nothing about vintage watches, I had a "coup de coeur", negociated the price a bit (!) and bought it.
After that, I began to search for some more information about it.
The watch sounds rather antique, at first glance, I would have said from the 40s, possibly the late 30s, but considering its gorgeous condition, I began to believe it was from de 50s or even 60s with a 40s look.
The seller - an antique dealer, is a vintage watches lover, but - in my opinion - not a real expert. He mentioned on the invoice that it was a Geneve model, but, after having done some research, I am almost certain it is a mistake.
The only similar watch I have found on the net, is here, https://thewatchcollector.co.uk/products/omega-rare-fab-suisse-cal-28-18ct-rose-gold/ ( with different hands, though...)
I was wondering if someone could help in identifying this watch…? On the site mentioned above, it is said circa 1944 ( which corroborates my feelings), cal 28, BUT I wonder what "10 million series" means?
I know I should have the watch open to get some more informations, especially the serial number, but I do not want to do it by myself, and I am currently in a kind of remote location with no professional to do it for me!
I cannot believe it is a fake or anything like that. It is such a gorgeous, good looking and obviously high quality watch! It gives the time for 48 hours at perfection ( so far)...
So, if I may ask, any kind of further information(s) would be greatly appreciated.
Thank you very much to all!

It's a lovely watch. It would be interesting to see the movement and its condition, as compared to the dial. A lot of what is discussed here is from a collectors'/ hobbyist viewpoint. Ultimately, I'm sure your husband is going to enjoy it, so getting into the details at this point may not really be that important. I agree with you, not to attempt to open that watch.

That’s a very elegant watch !

I thought that this type of case was for chronometers…

You can share your location if you want some recommendations for craftsmen, or search here on the forum.

If this all checks out, I think this is a remarkable find, and Monsieur Aggie is one lucky fellow. May I just ask one thing though - there is quite a gap between the edge of the strap and the lug near the 11 o'clock position, which does not appear to be present next to the other lugs - can you say what is the issue there?
Good luck with the birthday! (and please correspond with my other half through the international wives union, to let her know what standards are now being set) 😁

I'm unable to recognize the case. The dial and hands seem authentic enough, but the case (and crown) escapes me.

Please share a photo of the movement and inside of the caseback.

Thanks,

Hi! Thanks to all for your interest. Actually, the watch is not going to be openned for the moment. Of course, it will be much more interesting once openned! I was curious to know if anyone has ever seen such a watch, but, apparently, nobody does. I came to conclude that it possibly is a bespoke watch. Before the rationalisation of models it was very usual. I am going to offer the watch to my husband " as is", wrapped in a bit of a mystery, which, after all, is much more interesting than unadorned truth. It is much better to let some room for the imagination! But please, feel free to post your comments about the watch, I am very interested and I will post new developments, if I have some!

Yes, I agree. It is what I meant by " bespoke". Some kind of local finition.

Have you had a look on this one:

Tony's strap fits the lugs better than yours! 😁

Ha! Ha! No it is not a language issue but an "approximation" of speaking...
