Omega

Omega Constellation C-Shape Ref. CD 166.0247 is a luxurious statement from the late 1970s—an era when Omega embraced bold case designs and modern aesthetics. This particular reference carries the legacy of the Constellation line while introducing a solid gold build and a touch of ‘70s flair. With its distinctive C-shaped case and chronometer-certified movement, it offers a timeless blend of prestige and precision.

The watch features a vertically brushed or champagne sunburst dial, depending on the variant, accented by applied gold baton indices and slim baton hands. A framed date window at 3 o’clock keeps the layout functional and refined. Housed in a 35mm solid 18K yellow gold case, the “CD” prefix (Caisse D’or) confirms its rare full-gold construction—making it a standout for collectors who value understated luxury.

Powered by Omega’s Caliber 1011 automatic movement, this piece combines high-beat accuracy, quickset date functionality, and COSC-certified reliability. It’s a vintage dress watch that doesn’t shout but quietly asserts its significance through heritage, materials, and design.

Whether you're a connoisseur of vintage Omega or simply appreciate classic elegance with substance, the Constellation CD 166.0247 is a piece that elevates any collection.
