Omega Constellation Chronometer Automatic Day Date
by Devaka Wickramasuriya
I received as a gift from a close relative an Omega Constellation Chronometer Automaic Day Date watch. It was serviced at the Omega Agents in Singapore, The Swatch Group S E A, Keppel Bay Tower, Singapore,vide Repair No: 207645744, SD No: 110727629 as indicated in their Invoice dated 08th September 2015. This same invoice gives the Watch Reference No. as CD1680057. On removing the case back the following numbers are visible - 150097 & 1021. Can I please know the exact model of my watch as well as any other details (such as Year, Manufacture date etc) which I would like to have purely for sentimental reasons.
