Hello Hoi,
nice watch you have here!
I can not help with a ref# but at least I can assure you that the number on the outside of case back is the factory original serial number!
Normally these "outside" serial numbers are always associated with other inscriptions as we all know - a serial number on the outer edge of the case back is very uncommon though.
I have a ref 2254 with this kind of very uncommonly placed serial number of the same time period and have an extract from Omega as proof of authenticity for the watch.
I think the only way to find out the ref# is to order an extract from Omega.
kind regards
Erich

...is the earliest numerical reference number that Omega called "Seamaster":

However, it was not marked on the dial. I've seen numerous vintage ads for unmarked Seamasters.
The Omega database shows about a dozen different Seamaster references listed as originating in 1949. I'm sure that there were many of that group which were introduced around the same time, so it may not be possible to say which one was truly first, unless it is specified in one of Omega's two reference books.
Hope this helps,

...there really are no rules. The late 1940's/early 1950's was just a very jumbled period for Omega.
Here are some pages from a 1950 Omega Catalog:
Even in this catalog (probably Swiss or French- note the Fr.'s), the reference numbers do not match the nornal Omega references we use today.
Omega wasn't consistent about putting any model names on the dials until the introduction of the Constellation in 1952. Even then, there were variations without model names (like the original Globemasters). Also, some later references were produced with and without the Seamaster name depending on the market.
Generally, I defer to the Omega database if I can't find any information to the contrary,

Hi Gator,
you are right about the ref## in the catalogs, they are quite different from the "real" ref## which can be found in the case backs (if available).
The reason? Were the ref## in the catalogs just only for marketing purpose? Strange, isn´t it?
Please show us some more pages of your catalog - would be much appreciated!
kind regards
Erich
... in my Photobucket account. I'm not sure if I am allowed publish the link. My user name on Photobucket is same as here. Go under "Watch Photos", then "1950 Omega Catalog".

Hi Gator,
thank you very much for your kind information!
It worked very well. I am always keen on this old publications...
kind regards

if the number on the caseback refers to the 'serial number' it doesnt coincide with the serial number of the movement so its possible that the movement has at some time been changed for one that just happens to be older.
just a thought
