As you can see from the capture from AJTT the 2393 is a slimmed down version of the 2079, so perhaps this is the other version you are seeing. the excerpt also shows one with reference 2080 so that gives two alternative references you can investigate.
POCKET OMEGA: Thank you for taking the time to reply to my posts OllieOnTheRocks. Well, I bit the bullet and had the case back removed. Cristos071 was correct; it is a 2393/3.

OLLIE: Authentic Omega printing even back in this era is crisp and clear.
POCKET OMEGA: I would expect that Omega printing back then was crisp and clear but I guess my question was really whether or not this was true 100% of the time or are there known exceptions where issues were present in known original dials? It seems like 9 times out of ten, when I review an image of a Chro 33.3 (and I have looked at dozens and dozens) that there is something that looks not quite right. Be it font thickness, spacing, railroad thickness etc. Is it that the vast majority of Chro 33.3 dials out there are not 100% original?
OLLIE: To me it is the circular brushing on the two tone silver section of the dial that I find quite unusual. I would usually expect the brushing to be in one linear direction.
POCKET OMEGA: I did find this watch online which appears to have circular brushing. Also, it has "Swiss Made" on the dial. Perhaps another redial? The "Swiss Made" is at a different location on the dial. But then, the design of the dial is differs on each dial so the placement and font will be different on each dial?
Here is a link to the above picture. You will see several other pictures of Chro 33.3's which have "Swiss Made" on them or just "Swiss" very faint on the edge of the dial below the 6 O'Clock marker.

OLLIE: I own that same dial, in another case - reference 2092, see below. You'll note that it's not actually a grey silver, but rather a very white silver that has patinated over time.
POCKET OMEGA: Very beautiful watch! I understand your point about grey silver vs white but my previous picture re: circular brushing seems to show a quite metallic/grey looking finish on the hours ring. Perhaps it is a redial IDK.
I did notice what look to me like spacing and font issues in your watch picture above. I am in no way saying it is a redial. Please don't take this as an attack. Simply trying to become more proficient in identifying redials or not. I am assuming yours is an original and not a redial. That said I noticed. For example, that the spacing in the "23" and "24" appears wider between the 2 and the 3 in "23" than it does in between the "2" and the "4" in "24". Also the "6" hour border below the top of the "6" appears a little irregular. Perhaps this is because we can now zoom in on photos so much? See photo below:
OLLIE: The differences in thicknesses should be consistent across the printed artefact, but can be different between models depending on how much ink is on the pad. Could you point out the section that you think looks incorrect on Mark's photo? But like I say there can be thicker fonts that others.
POCKET OMEGA: I don't know what to say other than, as I mentioned above re: 9 out of 10 Chro's have issues to my eye. I guess the section which looks incorrect on Mark's photo is all of the overlap shown in the picture below. A little surprising, to me anyway, that Omega would design such a cluster:
OLLIE: I would suggest the second hand was not red to begin with and was blued like the other hands. It has been painted which has given it extra thickness.
POCKET OMEGA: I appreciate your comment. I did find another Chro 33.3 photo (below with a Link) with a red seconds hand where the red paint appears to be peeling off. It appears that red seconds hands were rather uncommon in Chro 33.3's? Perhaps the below is just another instance of a repainted second's hand or perhaps an original red paint used by Omega is inclined to peel away with time?

OLLIE: I'm not sure I can see an inconsistency here (on the left sub dial), however it would look like there are inconsistencies on the right hand sub dial.
POCKET OMEGA: Comment noted.
OLLIE: I would say that "fab suisse" is more common on watches of this era than Swiss made. Furthermore the example you provided showing swiss made does not look like the font and placement of yours. When used these are most always identical. Yours is higher above the second track. The spacing is off and the font is different.
POCKET OMEGA: Please see my previous link above and repeated here:

OLLIE: Hope that helps!
