Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Small Seconds 38mm Stainless Steel Sedna Gold Bezel White Dial Diamond Set Index Steel Sedna Gold Bracelet 220.20.38.20.55.002 - BRAND NEW Omega Seamaster Aqua Terra 150M Co-Axial Master…

The Omega Seamaster Aqua Terra 150M is one of the most versatile and enduring collections in modern Swiss watchmaking, drawing its DNA from Omega's legendary maritime heritage while delivering the polish and refinement of a dress watch. Introduced as a bridge between the rugged Seamaster Professional line and the elegance of the Constellation family, the Aqua Terra has earned a devoted following among collectors who refuse to compromise between sport and sophistication. Reference 220.20.38.20.55.002 represents the collection at its most luxurious, pairing precious materials with Omega's most advanced movement technology.

At 38mm in diameter, the stainless steel case occupies a sweet spot that suits a wide range of wrist sizes and sits as confidently under a shirt cuff as it does on display at a cocktail reception. The case is paired with Omega's proprietary Sedna gold bezel — a rose-gold alloy developed in-house to resist fading and color shift over decades of wear — which frames the dial with a warm, distinguished glow that contrasts beautifully against the cool brushed and polished steel of the case flanks.

The white dial is set with diamond indexes in place of applied hour markers, elevating this reference well above standard Aqua Terra configurations. The small seconds sub-dial, a hallmark of this particular variant within the 150M family, adds horological character and visual asymmetry that collectors appreciate. Every detail of the dial — from the teak-pattern horizontal lines to the crisp printing — reflects Omega's exacting standards of finishing.

Powering this watch is Omega's Co-Axial Master Chronometer movement, the pinnacle of the brand's in-house caliber development. Master Chronometer certification, awarded by the Swiss Federal Institute of Metrology (METAS), demands that each movement pass eight rigorous tests covering precision, magnetic resistance, and performance in real-world conditions — a standard that goes beyond the traditional COSC chronometer certification. Buyers can own this watch with complete confidence in its long-term accuracy and reliability.

The two-tone bracelet, blending stainless steel links with Sedna gold accents, is more than a design flourish — it creates a cohesive, unified aesthetic from case to clasp and ensures the watch wears as a single harmonious object on the wrist. The bracelet is fitted with Omega's secure deployment clasp and is designed for lasting comfort during extended wear.
