The Omega Constellation Chronometer Quartz Bi-metal. It’s a lovely vintage genuine Omega. It’s in need of a good service, polish and needs a new battery. I believe it’s from the 1970’s. I purchased this watch from the Watches of Knightsbridge auction back in 2012. I’m selling a few watches from my vintage Omega collection. I’m sad to see this go. Once it’s purchased and shipped I won’t be accepting returns in order to avoid any funny business. I am happy to answer all your questions to take additional pictures if required.

Omega Constellation Chronometer circa 1972 with Cal.1011 23 Jewel movement. Very nice watch, working, but movement clearly would benefit from a clean and service, as with all vintage watches accuracy and timekeeping cannot be guaranteed. That being said, this is a great example of a 1970s Omega which appears to have its original bracelet in good cosmetic condition. Slight fix needed on buckle. 593 end links and 1040 clasp, beads of rice bracelet.
