About this watch

The Omega Seamaster Aqua Terra 150M Co-Axial 30 is a masterpiece of horological innovation, blending advanced technology with luxurious design. Its self-winding Caliber 8521 movement boasts precision and reliability thanks to its Co-Axial Escapement, ensuring accuracy and longevity. The watch's red gold case is durable and visually stunning, complemented by a mother of pearl dial that shimmers with iridescent quality. Diamond-set bezel and indexes add opulence without excess, while the 30mm diameter makes it perfect for smaller wrists. A water resistance of 150 meters ensures durability in wet conditions, making it ideal for active lifestyles. The watch's Geneva waves in arabesque finish speak to Omega's commitment to aesthetic excellence, making the movement as visually appealing as it is functional. With a power reserve of up to 50 hours and an automatic winding capability, this timepiece delivers on both form and function.
