About this watch

The Omega Constellation Co-Axial 27 represents a perfect fusion of elegance, functionality, and innovative technology. With its brushed red gold case, gem-set bezel, and brown mother-of-pearl dial, this watch is designed to captivate attention. At the heart of this watch is the Omega caliber 8521 movement, known for its reliability and precision.
