Omega Seamaster Aqua Terra Seamaster Aqua Terra, 231.20.43.22.06.002, Unknown, 43 mm, Grey

The Omega Seamaster Aqua Terra 150M Co-Axial Chronometer Annual Calendar 231.20.43.22.06.002 combines sleek design with sophisticated functionality. While it may appear as a classic three-hand model at first glance, it features an advanced annual calendar mechanism that only needs date adjustment once a year, on March 1st. Powered by the Caliber 8601 movement with Omega’s signature coaxial escapement, it offers outstanding anti-magnetic protection thanks to its silicon balance spring. The stainless steel and red gold case measures 43mm, with a see-through caseback showcasing the intricate movement. This new timepiece is both practical and stylish, making it perfect for daily wear in an increasingly magnetic environment.
