Omega Seamaster Aqua Terra 150M Master Co-Axial Chronometer 34mm Stainless Steel Yellow Gold Diamond Bezel White Mother of Pearl Dial Diamond Set Index Alligator Leather Strap 231.28.34.20.55.004 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most celebrated lines in modern Swiss watchmaking, born from Omega's storied Seamaster heritage and refined into a versatile, elegantly sporty collection suitable for both ocean adventures and boardroom appointments. Introduced as a bridge between the brand's professional diving watches and its dress-oriented Constellation family, the Aqua Terra has earned a devoted following for its clean, horizontal "teak" deck-inspired dial pattern, assured water resistance, and the continuous refinement of its movement technology. Reference 231.28.34.20.55.004 represents the collection's most jewel-rich, fashion-forward expression.

At 34mm in diameter, this reference is sized with deliberate intention for a refined, wrist-flattering fit that has long been the benchmark for luxury women's sport watches. The case is crafted in stainless steel with yellow gold accents, a pairing that delivers warm luminosity without sacrificing the cool, enduring appeal of polished and brushed steel surfaces. The silhouette retains the Aqua Terra's characteristic integrated lug design and polished case flanks, giving it an effortlessly dressy profile.

The dial is the watch's most captivating feature: genuine white mother-of-pearl, a material prized for its naturally shifting iridescence that changes character with every movement of the wrist and every shift in ambient light. Diamond-set indexes replace conventional hour markers, scattering light across the dial and elevating legibility into an act of adornment. The diamond-set yellow gold bezel frames the scene with continuous brilliance, forming a unified aesthetic between the case, dial, and the meticulously set stones.

Beneath the exhibition or solid caseback, the watch is driven by Omega's Master Co-Axial Chronometer movement, a caliber that incorporates the brand's proprietary Co-Axial escapement to dramatically reduce friction and extend service intervals compared with traditional lever escapements. Master Chronometer certification, awarded through testing by METAS (the Swiss Federal Institute of Metrology), guarantees exceptional precision, magnetic resistance, and reliability — standards that go beyond the already demanding COSC Chronometer criteria. Owning a Master Co-Axial Chronometer means wearing a movement that the industry recognizes as a benchmark for modern mechanical watchmaking.

The alligator leather strap ties the entire composition together with supple luxury, offering a tactile counterpoint to the hardness of steel, gold, and diamonds. Its texture and warmth make this Aqua Terra feel at home on a dressed wrist at any hour. The deployant or pin buckle — finished to coordinate with the case metals — ensures secure wear and ease of use throughout the day.
