I believe that Ref 2491...
...is the earliest numerical reference number that Omega called "Seamaster":
webcache.googleusercontent.com
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,

Thank you Erich. Yes, it's in very nice condition and it's strange enough for me keep it apart from the other Omegas from the same period. I will send Omega an extract request, maybe. Hi Mike. Thanks for your info, if you have a chance, please post a pic ...

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? Ple...

Hi Guys Typically , depending on who this catalog was for.. The local distributor of Omega watches might only wanted to use a 3 digit number for sales ordering process . I guess in there minds who would think that you need more then 1000 unique watch IDs ...

Hi Omega movement serial number and case serial number ( pre 1945 or so). Almost never matched !! and this is typical. I think the only time it match was on the 10,000,000 watch produced where they synced up the case and movement serial number ( and maybe...
Finishing Swirls.
By: hoipolloi : February 14th, 2012-06:42
Hi Graham. Yes, Bill is right. ============ I don't know if anybody here notice the finishing swirls that Omega put on "the other side" of the early 30s and T1s movements. They stopped doing that on later T2's. Here's what I mean Early 30T2 with no swirls...
