Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Ladies 38mm Sedna Gold Diamond Bezel White Diamond Index Dial Alligator Leather Strap 220.58.38.20.99.006 - BRAND NEW Omega Seamaster Aqua Terra 150M Co-Axial Master…

The Omega Seamaster Aqua Terra 150M is one of the most celebrated sport-elegant watch lines in the modern era, drawing on Omega's deep connection with the sea while delivering a refined, dressy sensibility that transitions effortlessly from casual luxury to formal occasions. Introduced as part of the broader Seamaster family, the Aqua Terra earned its reputation through clean horizontal "teak" or gem-set dials, robust water resistance, and the brand's most advanced movement technology—all housed in cases that feel at home on the wrist whether poolside or at a gala. Reference 220.58.38.20.99.006 represents the collection's most opulent expression, conceived specifically for the discerning woman who wants performance and jewellery in a single, authoritative package.

The 38mm case of this reference is fashioned entirely in Sedna Gold, Omega's proprietary 18-carat rose-gold alloy developed in-house to resist fading and maintain its warm, distinctly rosy hue far longer than conventional rose gold. Sedna Gold achieves its remarkable color stability through a carefully guarded blend of gold, copper, and palladium, making it as technically innovative as it is visually captivating. On a 38mm footprint the case strikes an ideal balance—substantial enough to command attention and to house a serious movement, yet elegantly proportioned for a feminine silhouette.

The dial of reference 220.58.38.20.99.006 is set with diamond hour indices that catch and scatter light with every movement of the wrist, creating a dial that feels alive rather than static. Framing this gem-set face is a bezel pavé-set with diamonds, adding a continuous ring of brilliance that reinforces the watch's high-jewellery character. The overall effect is one of layered luminosity: the warm glow of Sedna Gold, the icy sparkle of white diamonds, and the immaculate white dial ground working in concert to produce something that is unmistakably both a watch and a jewel.

Powering the watch is Omega's Co-Axial Master Chronometer caliber, a movement that carries the industry's most rigorous third-party certification—tested and approved by METAS, the Swiss Federal Institute of Metrology, to confirm magnetic resistance to fields of 15,000 gauss, positional accuracy, and overall precision. The Co-Axial escapement, one of the most significant horological innovations of recent decades, dramatically reduces friction on the escape wheel, lessening the need for lubrication and contributing to long-term accuracy and durability. Owners of this reference benefit not only from extraordinary aesthetics but from a movement that outperforms many competitors in measurable, certified terms.

On the wrist, the watch is presented on a supple alligator leather strap that complements the Sedna Gold case with a tactile luxury of its own. Alligator leather remains the gold standard of fine watch straps—prized for its fine, consistent scale pattern, its softness against the skin, and its ability to develop a rich patina with wear. The combination of warm metal, diamonds, and fine leather creates a cohesive, head-turning ensemble appropriate for any occasion that calls for elegance.
