Omega Seamaster Aqua Terra 150M Master Co-Axial Chronometer 34mm Sedna Gold Diamond Bezel White Mother of Pearl Dial Diamond Set Index Alligator Leather Strap 231.58.34.20.55.003 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most distinguished sport-luxury watch families in modern watchmaking, tracing its roots to Omega's storied maritime legacy while translating that heritage into an elegantly versatile everyday companion. Introduced as a refined counterpart to the more technical Seamaster Professional line, the Aqua Terra was designed to move effortlessly between ocean-side leisure and formal occasions, earning a devoted following among collectors who prize both pedigree and wearability.

Reference 231.58.34.20.55.003 elevates the Aqua Terra concept into the realm of fine jewellery watchmaking. The 34mm case is fashioned entirely from Sedna Gold, Omega's exclusive 18-carat rose-gold alloy developed in-house to resist fading and maintain its warm, distinctive hue for generations. Sedna Gold's proprietary composition — incorporating copper, palladium, and gold — gives the case a depth of colour that standard rose gold cannot match, lending every curve and lug an almost burnished warmth.

The dial is a showcase of natural beauty and meticulous craft. White mother-of-pearl, harvested for its naturally shifting iridescence, forms the canvas, while diamond-set indexes catch and scatter light with every movement of the wrist. The diamond-set Sedna Gold bezel amplifies this luxurious statement, framing the dial with a continuous circuit of precisely matched stones. Together, dial and bezel create a watch that genuinely doubles as a jewellery piece without sacrificing legibility or the horological integrity Omega demands.

At its heart beats the Master Co-Axial Chronometer movement, a hallmark of Omega's modern engineering philosophy. The Co-Axial escapement, originally conceived by watchmaker George Daniels and adopted and refined by Omega, dramatically reduces friction within the movement, extending service intervals and improving long-term accuracy. Chronometer certification attests to rigorous independent testing, confirming precision performance across a broad range of temperatures and positions — a standard that reinforces the serious watchmaking credentials behind this jewel-set exterior.

On the wrist, the 34mm Sedna Gold case wears with understated authority. It is a size that suits a wide range of wrist proportions, sitting close and elegantly without overwhelming, and the supple alligator leather strap — chosen to complement the warmth of the gold and the delicacy of the diamonds — ensures comfort throughout a full day's wear. This is a watch equally at home at a black-tie dinner, a weekend brunch, or as a landmark gift to mark a significant occasion.
