Hi everyone,

I'm not very experienced when it comes to Vintage omegas and it seems to be quite a mine field. I found this one which I don't mind but found it odd that it had so little detail or really anything on the dial. I did a Google search of the case number (2902-1) and found a few other similar to it like this one here:
https://www.worthpoint.com/worthopedia/omega-cal-284-tone-dial-year-1956-251798973
And this one also on Omega forums:
https://omegaforums.net/threads/undefined-vintage-gold-omega-help-us-identify.5234/
From what I can see they appear to be the same apart from the second one I found being gold filled. I had a look at a guide that featured movement serial numbers, calibre's and the years that they were produced in.
https://www.ebay.com/gds/How-to-spot-Fake-and-Frankestein-Omega-/10000000177399639/g.html
The movement serial number was in the 15,000,000's and from the lists in the link above was from 1956 but I couldn't find the movement (284) being made in 1956 or at all. Of course this doesn't mean that it's fake but it did make me a little skeptical. I also looked on the vintage Omega website and there were no results for the serial number, just for something different. Seems like omega's archives are missing more watches than what they actually do have archived. Anyway I was hoping that someone with more knowledge in the field could help me out. Thanks in advance.

Regards,

Mark

The serial number puts the cal 284 from 1956, which seems fine to me. I think the movement and the reference is legit. It's a bit unusual to have lumed hands with an un-lumed dial, but not impossible.

Yeah sorry I meant 1956 not 1965, wrong way around haha. From what I could find it seemed to be legit. Thanks for the comment

Contrary to what the seller says, I believe it's a redial. Several of the minute markers appear to be unevenly spaced around the hour markers.

Yeah I was thinking the same thing as it looks a bit to new for a 62 year old watch

I agree. Especially around the 12 and 1 markers.

Another sign is that there should be a single T- next to SWISS MADE to denote lumed hands.

In 1965 perhaps but not 1956
(And you can see single Ts with lume on dial and hands)

"Newness" isn't a red flag in and of itself. I've got a few mint examples of watches that are as old and older. Some of the collections on this site would blow you away in respects of originality and mintyness.

It's the discrepancies that you need to look at. Pay attention to the markers between 2 and 3 ... I think they'll convince you its been reprinted.

Yep, redialled or cleaned. Lume in the hands, but not on the dial just doesn't exist in the world of post-30's Omega...

Am I the only one who flagged that it is missing the bezel? 🤦

So, in conclusion it is a watch with wrong hands, refinished dial and the bezel is missing.

Thank you everyone for sharing your knowledge and pointing out the discrepencies with the watch.

All that work on the dial and case, and they couldn't even be bothered to clean the movement?

Ok, noted.

But did any watches that had tritium lume (either hands or dial) come without any Ts whatsoever?

In the Omega change over period from radium to tritium, the Tritium dials generally didn’t have Ts.
Up to around ‘63
After that Ts should appear on tritium dials until the early 70’s when they disappeared again on some Omegas.
