I believe it is a calibre 505 model 293. Constellation grand luxe has the hooded lugs which are typical of this model.
MIne has the stepped dial, while others have polished pie pan steps.
May I suggest you look in the Sales area of the Forum?
You may be pleasantly surprised by some of the pieces offered there.
Note: I have no association with any of the sellers, but there is probably no better place to find an honest piece.
I literally just now finished up reading an article on Desmond's blog about the De Luxe line and there I saw for the first time the stepped dial. Then I open Omega Forums and see your post!

Alas, stepped dials in the De Luxe Line are apparently quite uncommon and buying a Grand Luxe, I imagine, is well beyond my budget of 4000-4500EUR.
Stepped faceted dials notwithstanding, I really like the aesthetic of the polished facets. So far, early in research, 2 references are emerging as favourites - 2853 and 14382. Of course, there is still so much to learn about this illustrious line of watches, including the movements and the case designs

Ever since I decided to take the plunge and buy my first expensive watch (which I do intend to keep for the rest of my life and pass on to next generation), I have been checking the private watch sales forums daily (first thing I get out of bed and just before I go to bed).

The last mention of De Luxe was by a senior member on this forum,
@Hijak, who sold this magnificent example of a Cal. 2799.

I am resisting my urge hard not to get a Rolex Explorer 36mm (114270), because I know I'll always be lusting over a Constellation, but they seem to rarely come up on Omega Forums and I don't feel comfortable buying from eBay and Chrono24. :|
Anyway, thanks for your feedback! You have my grail watch
