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.
