About this watch

The Omega Seamaster Aqua Terra 150M Co-Axial 41.5 Red Gold / Grey (Model: 231.53.42.21.06.001) is a luxurious timepiece that embodies elegance, durability, and precision. With its striking beauty, high-quality materials, and impressive functionality, it's no wonder this model is often regarded as one of the standout pieces from Omega's prestigious lineup. The Aqua Terra family is like a versatile friend - elegant enough for formal occasions, yet rugged enough for everyday wear. This watch doesn't just sit on your wrist; it commands attention. The round shape is classic, yet the use of high-quality materials elevates it. The red gold case is a hallmark of luxury, while the sapphire glass is both scratch-resistant and crystal clear. The open back showcases the intricate workings of the movement, making it a joy to behold. At the core of this exquisite timepiece lies the Omega Caliber 8501 - an automatic movement that's powerful, refined, and designed for performance. With a power reserve of about 60 hours, you're guaranteed reliability, ensuring that the watch keeps ticking even when you take it off for a day or two. The inclusion of a chronometer certification means you're getting top-notch accuracy. Omega's Co-Axial escapement reduces friction between the components, enhancing longevity and precision.
