It looks nice. But i have never seen this type of numerals on an omega. The logo looks like it is from the 50s, but i could be wrong. The case looks also from the 50s or 40s. It could be a later version of 30t2 (265, 26? etc. if i am not mistaken). It would help to open up the watch.
Do you know wether the dial has been refinished at some point or not?
