About this watch

The Omega Seamaster Aqua Terra 150M Master Chronometer is a masterpiece of luxury watchmaking, blending exceptional craftsmanship with sophisticated design. This stunning timepiece features a unique blend of Stainless Steel and Sedna Gold, giving it a luxurious feel without being overly flashy. The 38mm diameter comfortably sits on the wrist, making it suitable for various wrist sizes. The grey dial boasts depth and nuance that change under different lighting conditions, creating a unique look every time you glance at it. The gem-set indexes add a touch of luxury, while the arrow hands provide clarity and precision. At the center of this masterpiece is the Omega Caliber 8800, a self-winding movement featuring the innovative Co-Axial escapement. This technology reduces friction, enhancing the movement's longevity and precision. The watch is tested according to the Master Chronometer certification process approved by METAS, ensuring precision, performance, and resistance to magnetic fields up to 15,000 gauss. With a power reserve of 55 hours, you can confidently take this watch off for a weekend without worrying about it losing time. The sapphire glass adds an additional layer of protection, ensuring that the watch remains scratch-free over time. Whether you're at the office or out for a dinner date, the Aqua Terra seamlessly transitions between different settings.
