I'm new to the forum and also to watch collection, although I have been researching for a couple of months.
Finally, I'm having the opportunity to start my collection with a vintage Omega, Automatic, 1950, ref 2597-6 cal 351. It seems to be a good deal here in Brazil.
I'm not sure though that the dial is original (nor the crown). Please let me know your thoughts about the watch (thanks in advance!):
