About this watch

The Omega Seamaster Aqua Terra 150M Master Co-Axial 34 Sedna Gold / MOP is a masterpiece of luxury watchmaking, combining exquisite design with precision and reliability. The Sedna Gold case is visually striking, while the Mother of Pearl dial is a showstopper, featuring unique swirling patterns that reflect light in an ethereal way. The Omega caliber 8521 movement, powered by a Co-Axial escapement, reduces friction between moving parts for enhanced accuracy and longevity. With a water resistance of 150 meters, this watch can withstand the rigors of both land and sea adventures. Its versatility is unparalleled, transitioning seamlessly from formal to casual wear. The adjustable clasp ensures a perfect fit on most wrists, while the soft leather strap or gold bracelet adds to the overall comfort. This timepiece is an investment in luxury, craftsmanship, and innovative technology, making it a lasting symbol of style and a testament to Omega's commitment to excellence.
