About this watch

The Omega Constellation Co-Axial 35 Yellow Gold / Diamond / Silver is a masterpiece of luxury watchmaking. Its stunning design, featuring a round case crafted from yellow gold and adorned with gem-set indexes, is visually captivating. The silver dial complements the gold beautifully, creating a harmonious balance that is both elegant and sophisticated. With its compact size of 35.00 mm, this timepiece is perfect for smaller wrists while still making a bold statement. The closed case back adds to the sleekness of the design, giving it a classic look that never goes out of style. This model features a gem-set bezel that truly stands out, adding an extra layer of luxury and sophistication. The sapphire glass not only adds a layer of protection but also enhances the overall shine of the watch, making it perfect for both casual outings and formal events. Underneath its luxurious exterior lies the heart of the Omega Constellation—the Omega caliber 2500. This automatic movement is renowned for its Co-Axial escapement, which significantly reduces friction among the movement's components, resulting in improved accuracy and longevity. With a power reserve of 48 hours, you won’t have to worry about winding it daily. Just strap it on, and you’re good to go for a weekend getaway! One of the standout features of the Omega Constellation is its water resistance of up to 100 meters. Whether you're caught in the rain or diving into a pool, this watch can handle it all. It’s practical yet stylish, a combination that’s hard to come by! The gem-set indexes on the dial are an exquisite touch, adding a level of luxury that's hard to ignore. They not only serve as markers but also catch the light in such a way that they sparkle with every movement of the wrist. Coupled with the Dauphine hands, which are elegant and easy to read, the watch offers a perfect blend of functionality and form. The hands sweep gracefully across the dial, making time-telling a delightful experience. Comfort is key when it comes to wearing a luxury watch, and the Omega Constellation does not disappoint. The bracelet, made from yellow gold, feels smooth against the skin and is designed for a secure fit. The folding clasp is easy to operate, ensuring that the watch stays securely on your wrist without any fuss. This timepiece is incredibly versatile. Whether you're dressing up for a gala or keeping it casual for brunch with friends, the Omega Constellation Co-Axial fits the bill.
