About this watch

The Omega Seamaster Aqua Terra 150M Co-Axial 30 is a stunning example of luxury watchmaking. This unisex timepiece combines the elegance of a dress watch with the functionality of a sports watch. The white gold case and mother-of-pearl dial exude a luxurious vibe, while the gem-set indexes add a touch of sparkle. Powered by the Omega caliber 8421, this self-winding movement features a Co-Axial escapement, reducing friction and increasing durability. With its water resistance of 150 meters, this watch can handle active lifestyles. The ergonomic design ensures comfort all day long, making it perfect for dressing up or down. As a testament to Omega's legacy in horology, the Aqua Terra 150M is more than just a watch - it's a piece of art and engineering that can be passed down through generations.
