Hi omega lovers, I'm new at this forum and I just receive my grandfather's omega and I would like to identify it. It's automatic, gold, and has this particular thing that i can't find in other vintage omega watches that i saw: The numbers shown are the 2, 4, 6, 8, 10 and 12 instead the usual 3, 6, 9, 12. I know that the bracelet isn't original. It was replaced two years ago by this "not so expensive" bracelet. I would like to know how it is the original one and try to find one. I'm affraid to open it since the concave screen has already a small crack. By the way... Great forum, Congratilations Greetings from Portugal
