Hi, I am selling my Omega Cal 342 case reference 2576-10 with a serial of 11.5 million. This dates around 1949 from my research and this model was produced from 1949. The movement is running very well. The dial has a nice patina to it and has aged gracefully. The case is around 34mm excluding the crown. All in all a very nice vintage Omega. I am asking $US695.00 net to me. This price will include shipping worldwide. I accept PayPal at buyers expense. Any further questions please don't hesitate to ask.
