Hi, I am offering my Omega cal 30 second batch serial number from 1938/39. The watch has a very nice clean movement and running very strongly. The case is around 33 mm excluding the crown which could be a replacement and is also in good condition. There is a small amount of ghosting around the numbers but the dial is otherwise in great condition. I am asking shipped worldwide net to me $US800.00. PayPal is acceptable plus 3%. Any questions please don't hesitate to ask. Cheers Russell.
