About this watch

The Omega Seamaster Aqua Terra 150m Master Co-Axial 38.5 is a masterpiece of horology, blending elegance with robust functionality. With its exquisite design, impressive technical specifications, and reputation that precedes it, this watch is more than just a pretty face. The combination of yellow gold and stainless steel creates a rich visual appeal, while the silver dial adorned with stick and dot indexes adds to its refined look. The sapphire glass ensures durability and scratch resistance, making this beauty perfect for everyday wear. At the core lies the Omega caliber 8500, introduced in 2007, a true marvel of engineering offering precision and reliability. The Co-Axial escapement reduces friction between components, enhancing the longevity of the movement. This watch doesn't just keep time; it does so with remarkable precision, marked as a chronometer for meeting high standards of accuracy.
