Here is an all-original Omega Constellation in solid 18k gold measuring 35.5mm and 10mm thick. The original winding crown is present and the Omega crystal is signed. There are only very minor and usual marks on the case from normal use. This dial is completely original and I can not find a flaw anywhere. The Dauphine hands are original. The automatic winding caliber 561 movement was just cleaned, is accurate, and the serial number dates this watch to 1966.
