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.
