The Omega Constellation (Ref. 123.57.35.20.55.001) represents the convergence of Swiss fine jewelry and the mechanical tradition of the Bienne-based house. Crafted entirely from 18-karat red gold with a 35-mm case diameter, this model stands out for its understated proportions (38.40 mm from lug to lug and 10.76 mm thick), offering a look of great distinction on the wrist.

Its white dial serves as a backdrop for diamond-set hour markers, framed by a red gold bezel studded with a continuous setting of brilliant-cut diamonds flanked by the iconic side claws. At the 3 o’clock position is the date window, discreetly integrated into the design. The entire watch is protected by a scratch-resistant convex sapphire crystal with an internal anti-reflective coating, paired with a solid 18-karat red gold bracelet for a total weight of 104 grams.

Inside beats the self-winding OMEGA Caliber 2500, historic for incorporating the Co-Axial escapement to ensure greater chronometric precision and long-term mechanical stability. The case back ensures the movement’s protection, offering water resistance of 10 bar (100 meters).
