Bold, iconic, and unmistakably OMEGA, the Constellation collection has long been celebrated for its signature half-moon facets and distinctive “claws” that frame the case.
This 41 mm masterpiece, crafted in stainless steel and 18K yellow gold, makes a striking statement with a black polished ceramic bezel, featuring Roman numerals in lustrous OMEGA Ceragold™. Its sun-brushed green dial, enhanced with a subtle gradient effect, captures light from every angle, while a date window at 6 o’clock provides perfect balance and functionality.
The hands, OMEGA logo, Constellation star, and indexes are meticulously executed in 18K yellow gold, adding warmth and elegance to the bold dial. Departing from the classic mono-rang bracelet, the timepiece is fitted with a green leather strap lined with rubber, blending sporty comfort with sophisticated style.
At the heart of the watch lies the OMEGA Co-Axial Master Chronometer Calibre 8900, offering exceptional precision, durability, and resistance to magnetic fields. The movement’s refined finishing can be admired through the scratch-resistant sapphire crystal caseback, revealing the technical artistry within.
