Product Description

The Omega Constellation Co-Axial Master Chronometer (Ref. 131.10.36.20.01.001) reimagines one of the most legendary designs in Swiss haute horlogerie. Housed in a 36-mm stainless steel case, this model stands out for its compact and versatile proportions (39.20 mm lug-to-lug), while maintaining the collection’s unmistakable identity with its iconic lugs at 3 and 9 o’clock and the bezel engraved with Roman numerals.

Its black dial with a sunburst brushed finish offers a sharp and mesmerizing contrast, enhanced by 18-karat white gold applied hands and hour markers to ensure lasting brilliance. At the 6 o’clock position, the date window is harmoniously integrated alongside the iconic Constellation star. The dial is protected by a scratch-resistant convex sapphire crystal with an anti-reflective coating on both sides, complemented by an integrated bracelet with articulated links in stainless steel, weighing 145 grams.

Inside, the self-winding OMEGA Caliber 8800 beats, visible through the transparent sapphire crystal case back.

Certified to METAS’s stringent Master Chronometer standard, this high-precision movement offers a 55-hour power reserve, complete immunity to everyday magnetic fields of up to 15,000 gauss, and improved water resistance of 5 bar (50 meters).
