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. It features a self-winding mechanism with a Co-Axial escapement, which enhances the watch’s accuracy while reducing friction. The Omega Constellation Co-Axial 27 boasts an impressive water resistance of up to 100 meters, protected by a sapphire crystal. This makes it suitable for swimming and snorkeling, although it’s advisable to avoid diving. With a power reserve of 50 hours and a frequency of 25,200 vibrations per hour, this watch is engineered for performance.
