This is an an uncommon and VERY thin (7.4mm) Omega Constellation with case measuring 34mm and having an all dial appearance due to the narrow bezel. The patina on the outer edge of the original dial appears MUCH less visible in person than in my brightly lit close-up photos. The correct Omega winding crown is installed. The movement is the very fine and thin automatic caliber 712 chronometer grade-just cleaned and is accurate. This watch is seldom seen and priced extremely well.
