Omega Seamaster Aqua Terra 150M Master Co-Axial Chronometer 34mm Stainless Steel Sedna Gold White Mother of Pearl Dial Diamond Set Index Steel Sedna Gold Bracelet 231.20.34.20.55.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most celebrated collections in Omega's storied catalog, born from the brand's deep maritime heritage and its long association with sailing, the ocean, and precision timekeeping. Introduced as a versatile companion for life both on and off the water, the Aqua Terra line elevated the Seamaster's sporty DNA into something unmistakably refined — a watch equally comfortable in a boardroom or on a yacht deck. Reference 231.20.34.20.55.001 represents the collection's most luxurious expression, uniting haute horlogerie with genuinely wearable elegance in a 34mm format designed for those who appreciate both artistry and performance.

At 34mm, the case size strikes a confident balance: substantial enough to command attention on the wrist yet perfectly proportioned for a refined, feminine silhouette. The case itself is crafted from polished and brushed stainless steel, offering excellent durability and corrosion resistance, while Omega's exclusive Sedna Gold — a proprietary 18k rose gold alloy formulated for lasting color stability — adorns the bezel and bracelet in warm, enduring tones. The interplay of cool steel and warm Sedna Gold gives this reference a two-tone personality that feels contemporary and timeless simultaneously.

The dial is the undisputed centerpiece of this reference. A white mother-of-pearl surface catches and refracts light with every movement of the wrist, producing the organic shimmer that only genuine MOP can deliver. Diamond-set indexes replace the standard applied hour markers, introducing a quiet, brilliant luxury that elevates this Aqua Terra well beyond conventional sports-watch territory. The result is a dial that rewards close inspection — the kind of detail that distinguishes a truly special timepiece from a merely good one.

Beneath the dial beats Omega's Master Co-Axial Chronometer movement, a caliber certified by the Swiss Official Chronometer Testing Institute (COSC) and additionally certified to Omega's own Master Chronometer standard by METAS — meaning it has been tested and verified to perform with exceptional precision, magnetic resistance, and reliability. The Co-Axial escapement, one of the most significant horological advances of the modern era, reduces friction in the movement and extends service intervals, ensuring long-term accuracy and reduced wear. This is a movement you can trust for a lifetime.

The integrated stainless steel and Sedna Gold bracelet echoes the dial's dual-material elegance, flowing naturally from the case and sitting comfortably on the wrist. Its construction reflects the same meticulous attention to finishing detail seen throughout — polished center links offset by brushed outer links create a visual depth that elevates the wearing experience. Whether paired with a cocktail dress or worn daily, this bracelet is as practical as it is beautiful.
