Omega Constellation Octagonal Massif

Omega Constellation Octagonal “Or Massif” 18K Gold Case · Automatic Cal. 712 · French Market · Circa 1970s The Constellation has long stood as one of Omega’s most refined expressions of precision and elegance. Born as the brand’s chronometer focused line, it quickly became a symbol of Omega’s ability to combine mechanical credibility with a more elevated design language. By the 1970s, that identity began to evolve into slimmer, more architectural forms, and this rare octagonal example captures that chapter beautifully with a shape that feels distinctly period, yet still strikingly elegant today. What makes this piece especially compelling is its uncommon octagonal case design paired with the “Or Massif” character of the French market execution. The clean champagne toned dial, slender baton markers, and restrained layout allow the geometry of the case and the warmth of the 18k gold construction to speak for themselves. It is exactly the kind of vintage Omega that feels quiet at first glance, but increasingly special the longer you look at it refined, sculptural, and deeply rooted in the dress watch language of its era. Measuring 28mm x 30mm with a 35mm lug to lug and a slim 7mm thickness, this Constellation wears with the graceful proportions expected from a true vintage gold dress watch. Inside beats the automatic Calibre 712, a movement from Omega’s celebrated period of slim and sophisticated watchmaking. With its rare octagonal form, French market appeal, and unmistakable Constellation pedigree, this piece stands as a highly distinctive vintage Omega for collectors drawn to subtle rarity and elegant design.
