Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Moonshine Gold 38mm Yellow Dial Diamond Bezel 220.55.38.20.99.002 - BRAND NEW Omega Seamaster Aqua Terra 150M Co-Axial Master…

The Omega Seamaster Aqua Terra 150M has long occupied a singular position in the world of luxury sports watches — elegant enough for a formal occasion yet robust enough for an active lifestyle. Reference 220.55.38.20.99.002 elevates that proposition to its most precious extreme, presenting the 38mm case, dial, and bracelet in Omega's proprietary Moonshine Gold, an 18-karat gold alloy engineered to retain its warm yellow radiance significantly longer than standard yellow gold.

At 38mm, this Aqua Terra strikes a silhouette that sits beautifully on a wide range of wrist sizes, offering the full visual impact of Moonshine Gold without the imposing bulk of larger sport-watch cases. The case architecture retains the Aqua Terra's signature clean lines — a gentle lug curve, a polished and brushed finishing interplay, and the collection's hallmark teak-pattern-inspired dial layout — all reimagined here as a canvas of yellow diamonds. The diamond dial shimmers with carefully set stones that catch light from every angle, while the diamond-set bezel frames the face with an additional tier of brilliance.

Driving this remarkable watch is Omega's Co-Axial Master Chronometer movement, a designation that signals the highest level of Swiss watchmaking precision. Master Chronometer certification, conferred by the Swiss Federal Institute of Metrology (METAS), demands resistance to magnetic fields exceeding 15,000 gauss and verified chronometric performance across multiple positions and temperatures — assurances that the movement inside this diamond-adorned case is as serious as any tool watch. The Co-Axial escapement also reduces friction and wear, contributing to longer service intervals.

On the wrist, the 220.55.38.20.99.002 is an unambiguous statement of refined luxury. The Moonshine Gold bracelet flows from the case with integrated proportions, its links combining polished and brushed surfaces that amplify the depth and warmth of the alloy. The yellow diamond dial catches light differently in every environment — from boardroom daylight to candlelit evening — making this a watch that rewards close attention and rewards it continually. It is equally at home paired with couture or with a beautifully tailored suit.

For collectors and connoisseurs, the combination of Moonshine Gold, diamonds, and Master Chronometer engineering within a single Aqua Terra reference is exceptionally rare. The 38mm sizing positions this piece as a versatile choice that transcends the traditional boundaries of gender in fine watchmaking, appealing to anyone who values both horological substance and precious materials. Its brand-new condition means it arrives with full manufacturer presentation and all factory protections intact.
