About this watch

The Omega Seamaster Aqua Terra 150M Co-Axial 30, model number 231.15.30.20.55.001, is a masterpiece of luxury watchmaking. Its stunning Mother of Pearl dial shimmers in a spectrum of colors, making every glance feel like a new experience. The gem-set indexes add an extra layer of opulence, transforming the watch into a piece of jewelry rather than just a tool for telling time. Crafted from high-quality stainless steel, the case and bracelet not only enhance the watch's durability but also its aesthetic appeal. At the heart of this timepiece lies the Omega caliber 8520 movement, featuring a Co-Axial escapement that ensures greater precision and reduces the need for frequent servicing. The watch displays hours, minutes, and seconds with ease, alongside a convenient date function. With a power reserve of 50 hours, you can leave it unworn for a couple of days without worrying about resetting it. This watch isn’t just pretty; it’s precise! With a water resistance rating of 150 meters, the Seamaster Aqua Terra is more than capable of handling a little splashing around. Despite its luxurious appearance, the watch feels surprisingly lightweight on the wrist. The stainless-steel bracelet is comfortable, making it suitable for daily wear.
