Hi, I am selling my Omega Constellation Chronometer (Ref. 168.047), which I purchased in July 2022. The upper-right of the bottom of the case appears to be engraved with the number "79," so I think this watch may have been manufactured in 1979. I don't know the accuracy of the movement or when the last service was but it is working. No known issues with the movement, display, or case other than minor scratches and a stripped lug at the bottom of the case, meaning the lug may be hard to remove if you wish to service the band. The travel case shown in the photos is for display purposes only and is not included.
