Omega Seamaster Aqua Terra 150M Co-Axial Chronometer 30mm Red Gold White Mother of Pearl Dial Diamond Set Index Red Gold Bracelet 231.50.30.20.55.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most celebrated lines in modern Swiss watchmaking — a collection born from Omega's storied marine heritage and elevated into a versatile, dressy-sport icon. Introduced in the early 2000s, the Aqua Terra bridged the gap between Omega's professional diving DNA and the polished sensibility of a luxury daily wear timepiece, earning fans among collectors, athletes, and style-conscious wearers worldwide. Reference 231.50.30.20.55.001 represents the most precious and feminine expression of that philosophy.

At 30mm in diameter, this reference is sized with deliberate elegance, making it an ideal choice for those who prefer a refined, closer-to-the-wrist presence without sacrificing any of the visual drama the Aqua Terra line is known for. The case, bezel, and integrated bracelet are all crafted in 18k red gold — a warm, richly hued alloy that imparts an unmistakable sense of luxury and is notably rarer in fine watchmaking than yellow or white gold. The result is a monolithic, all-precious-metal composition that feels both substantial and graceful on the wrist.

The dial is the undisputed centerpiece of this watch. A genuine white mother-of-pearl panel captures and refracts light in an ever-shifting, organic shimmer that no printed or lacquered surface can replicate. Diamond-set indexes replace the standard applied hour markers, adding brilliance at every glance and reinforcing the jewellery-watch character of the reference. Together, the pearl and diamonds against the warm glow of the red gold case create a palette of extraordinary refinement.

Powering the 231.50.30.20.55.001 is an Omega Co-Axial Chronometer movement — a technology that sets Omega apart from much of the industry. The Co-Axial escapement, developed in collaboration with master watchmaker George Daniels and industrialized by Omega, reduces friction in the gear train, extending service intervals and contributing to long-term precision. Chronometer certification means the movement has passed the rigorous independent timing tests of the COSC, guaranteeing performance to exacting standards. Buyers can wear this watch with full confidence in its mechanical integrity.

The Seamaster Aqua Terra 150M carries a 150-metre water-resistance rating by design heritage, making this an Omega that can accompany an active lifestyle even in its most precious configuration. Whether worn to a formal dinner, a weekend brunch, or a sun-drenched afternoon on the water, the 231.50.30.20.55.001 transitions effortlessly across occasions — which is precisely the promise the Aqua Terra collection has always delivered.
