Vintage Omega Constellation Automatic Chronometer

This is a vintage Omega Constellation wristwatch, likely dating from the late 1950s to the 1960s. The watch features a gold-toned case with a circular dial and a date window at the 3 o'clock position. The dial is off-white or champagne with faceted gold-toned hour markers and dauphine-style hands. Under the 12 o'clock marker, it bears the applied Omega logo and text identifying it as an 'Automatic Chronometer Officially Certified.' At the 6 o'clock position, the word 'Constellation' is printed above a gold-applied star. The watch is presented on a gold-toned expansion band, which appears to be a later addition or an aftermarket replacement. The case shows signs of wear, including scratches and possible plating loss on the lugs. The acrylic crystal displays significant surface scratching and small cracks, particularly around the edges, which is typical for its age. The crown appears original but shows wear and grime buildup. The dial has developed a light patina and some spotting, consistent with aging. This model is highly regarded for its high-grade movement and classic 'pie-pan' or flat-dial aesthetic, representing a pinnacle of mid-century Swiss horology. While the external condition is fair, the mechanical integrity would require a professional movement inspection to determine full value.
