Omega Seamaster Aqua Terra Seamaster Aqua Terra, 231.23.43.22.06.002, Unknown, 43 mm, Grey

The Omega Seamaster Aqua Terra 150M Co-Axial Chronometer Annual Calendar 231.23.43.22.06.002 is an elegant yet practical timepiece. At first glance, it appears to be a simple three-hand model, but it features an advanced annual calendar complication that only requires a date adjustment once a year, on March 1st. The watch is powered by Omega's Caliber 8601, which incorporates the Co-Axial escapement and a silicon hairspring, ensuring strong resistance to magnetic fields and enhancing long-term precision. The stainless steel and red gold case, paired with a gray dial, gives it a sophisticated look. With a 55-hour power reserve and 150-meter water resistance, it combines luxury with everyday functionality. The transparent case back allows for a view of the movement, further enhancing its appeal.
