Hello, I would like to ask If anybody could tell me more about my Omega Constellation. Calibre 711, ref 151.0048 or 151.8408. Gold case and dark wooden dial. I tried to find information from Omega webpages and other sources, but did not found much. I’m interested about value and any information about manufacturing time. If someone has similar model, it would be nice to see images.
The 71x series of movements was introduced in 1966. The serial number marked on the movement can be used to more closely date your watch.
