Omega Constellation Red Gold 123.20.38.21.13.001

The Omega Constellation Co-Axial Chronometer Ref. 123.20.38.21.13.001 is an elegant interpretation of one of Omega's most recognizable collections, combining the distinctive Constellation design with the warmth of 18k red gold. Its 38mm stainless steel case features the collection's signature four “Griffes,” or claws, positioned along the bezel, a design element that has defined the modern Constellation since 1982. The fixed 18k red gold bezel is engraved with Roman numerals, complementing the rich brown dial, applied hour markers, and matching red-gold-toned hands. A date window at 3 o'clock adds everyday practicality without disrupting the dial's balanced appearance. The integrated stainless steel and 18k red gold bracelet features alternating brushed and polished surfaces and a concealed butterfly clasp, giving the watch a refined, jewelry-like presence on the wrist. A domed sapphire crystal with anti-reflective treatment on both sides, sapphire exhibition caseback, and 100 meters of water resistance complete a design that blends traditional luxury with the durability of a modern Swiss timepiece.

Inside is Omega's in-house Co-Axial Calibre 8500, a 39-jewel automatic chronometer movement operating at 25,200 vibrations per hour and delivering approximately 60 hours of power reserve. The movement incorporates Omega's Co-Axial escapement, free-sprung balance, and twin mainspring barrels mounted in series, providing improved mechanical efficiency and consistent power delivery. Visible through the sapphire caseback, the Calibre 8500 features beautifully decorated bridges and rotor with Omega's signature arabesque Côtes de Genève finishing. The Constellation collection traces its origins to 1952, when Omega introduced the line as a showcase for its precision chronometer movements, eventually developing into one of the brand's most recognizable luxury watch families. With its versatile 38mm proportions, distinctive brown dial, solid 18k red gold accents, integrated two-tone bracelet, and sophisticated Co-Axial movement, the Ref. 123.20.38.21.13.001 offers a compelling combination of classic Constellation styling and modern Omega watchmaking.
