About this watch

The Omega Constellation Co-Axial 31 is a masterpiece that beautifully marries form and function. With its luxurious materials, sophisticated design, and reliable movement, it’s a watch that is sure to be cherished for generations. The combination of stainless steel and yellow gold creates a striking contrast that is both modern and classic. The gem-set bezel adds a touch of glamour, making it perfect for formal occasions or everyday wear. The dial is made of exquisite Mother of Pearl, which not only enhances its beauty but also gives it a dynamic quality. Depending on the light, the dial can appear in various colors, ranging from shimmering white to soft pastel hues. Featuring Dauphine hands, the watch ensures excellent readability. At the heart of the Constellation Co-Axial 31 lies the Omega caliber 8520, an automatic movement known for its precision and reliability. The Co-Axial escapement is a significant innovation that reduces friction between the parts, enhancing the watch's longevity and accuracy. With a water resistance of 100 meters, this watch is ideal for daily wear. Whether you’re splashing in the pool or caught in the rain, the Omega Constellation can handle it all.
