Vintage Art Deco Omega, struggling to find information

Hello everybody,

I am a new enthusiast, and I have recently found a watch auction and was rather attracted to this vintage Omega. The auction house states it's a ref. nº 9336228 with a cal. 26.5 SOB, they also provide the serial. I recognise that it may have been polished, however, I have further questions about the originality of finer parts such as the hands, sub hands and crown, as I struggle to find similar models online to compare with. Would it contain any radioactive material even without lume? I was wondering if anyone here with a bit of expertise might be able to help me verify if this watch is original and what a fair price for it might be? I’d really appreciate your insight! It is currently listed for 620 euros base price. I attached all photos I have access to.

It’s an Omega CK2023 - if you use google lens you’ll find some examples. It looks okay, but they are very small, 31 mm I think.

9336228 is presumably the movement serial number, which would date the watch to around 1940

I can't be certain from the photo, but if the dial has lume, the hands should have lume. Possibly a Portuguese import mark on the case, FWIW.

Hi, yes, it is a Portuguese watch auction. I don't understand. Are you stating that the dial currently has lume and therefore the hands are incorrect? I apologise, but I am slightly confused.

We are just as confused. I have an example of this watch:

However, my example has no radium and the leaf hands are painted black.

The hands on your watch seem to be the correct type (even the seconds hand, which is very difficult to find as a replacement). But I have never seen one of these with a radium dial. As stated above, a radium dial watch would have radium hands, otherwise no one would be able to see the hands in the dark.

The Omega logo on the OP’s example seems to be correct for a late 1930’s watch.

So my gut tells me that either the dial was partially repainted to resemble a sector version, or that the dial is original and someone replaced the hands with a factory correct set of gold-plated “leaf” style hands.

I’m not sure what happened here, but it is a nice looking watch, even if not quite right.

It may well be just white paint and not radium on the dial. I’ve seen this kind of dial before (I’m not at home for the moment and can’t post pictures for the moment but will do!)
