not a seamaster

Hi, I have been looking for a seamaster 30 and had found a decent one, but was putoff by lume possibly being radium - the whole story in another thread.... long story short, the guy that was selling that watch contacted me as he has a 1954 omega, likely not a seamaster as it has no marking. Movement is cal.266 I thought I might go look at it, I was just wondering if you wise people might have some advice on what to look for? Apparently it was just serviced and has a tolerance of 16 seconds/day. It is also claimed to be original. I am including some pics that I got from the seller, but of course they might not be too detailed. That did not worry me too much, as he is local.

I have read much of your input in the past, including the how to fish piece, which is excellent! Any tips are welcome. The other thing, that I would ask you is your views on using this as a daily wearer? not sure this may be appropriate given the age, but who knows? on this basis, Nomos also takes my fancy, quite much as a more modern alternative. Thanks for your insights!

Thanks Bill, here is the back of the watch pic. I only have these three, I just got this today as I was asking about engravings. For whatever reasons, over here engraving seem to have been quite popular at one point in time :/

Thank you @Bill Sohne and @MtV! Definitely your eyes are much more tuned into these details, like inconsistencies or worn out markings on the back. I definitely value your views. Indeed after a quick scan on pictures from similar years, it seems that the hand on the minute dial is a bit too short... Also, I thank you for the comment on the dial. Period coherence checks need experience which I don't have, so once again thanks! I will try to source some further information, and if I do, I will keep you posted.

Thanks @Dan S. As I see it, its fate is sealed 😀 I have to admit that the exploration process is very much fun and almost as good as the actual find, when it will come 😀 I have been learning so much from reading the views on this forum! Great stuff!

with that movement, it could be pre-seamaster or pre-connie.

Dial and hands are incorrect IMHO. I think the dial is a later service dial.
If 1954 my guess the watch is from the model line "Other"

Thank you once again for your valuable input! Many red flags that you guys have raised. Just a general question, to become more knowledgeable. When you talk bout later service dials, do you mean something that e.g. was taken by a similar/compatible model or do you mean something that is picked from a part catalogue? In the latter instance, are you aware of such catalogue? It might be a handy resource for running some background checks in the future. Any views or experience on this?

There is something... Off about it.

- The sunburst finish is too strong for an Omega of this age.
- It can't be a 2639 as those are screw-down caseback, so it could be a 2791 (or is it 2792? keep forgetting)? Those came with or without Seamaster typing on the dial.

My view: a ref 279X with replacement crown and hands and a dial someone has tampered with. Either service replacement or redial.

To be honest, the most interesting thing here is the worn-out Omega strap 😀
