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.
