I have just recently got my first Omega. A Seamaster Polaris SS/YG. Got it for 425 dollar on Ebay from a Japanese seller. I've read somewhere this model was not very popular. Still Omega produced watches with this design between 1982 and 1994? This model got a 54XXXXXX serial no.
I am about to save up for my next Omega. Which model I am not sure of yet.
I have owned Rolex and Breitling earlier, but these were sold in a bad financial period.
