About this watch

When it comes to luxury watches, few names resonate as profoundly as Omega. Renowned for its precision, craftsmanship, and timeless designs, Omega has carved a niche in the world of horology. The Omega Constellation Co-Axial 27 is a stunning creation that perfectly balances resilience with luxury. Its blend of brushed stainless steel and yellow gold immediately captures attention, while the gem-set bezel sparkles brilliantly at every angle. The beautiful mother of pearl finish on the dial reflects light in a way that adds depth and character to the timepiece. Equipped with the Omega caliber 8520, this watch offers automatic movement, ensuring accuracy and reliability. With a power reserve of up to 50 hours, you can comfortably take it off for a weekend without worry. The frequency of 25,200 vibrations per hour showcases Omega's commitment to precision. Being a chronometer, this watch has undergone rigorous testing to ensure its accuracy. It’s like having a Swiss watchmaker's seal of approval right on your wrist! With a water resistance of up to 100 meters, the Constellation Co-Axial 27 can handle splashes, rain, and even the occasional swim. Its versatility is unmatched, complementing any outfit whether dressing up or going casual. This Omega model holds its ground alongside other luxury watches, such as the Rolex Datejust or the Tag Heuer Carrera.
