Omega Seamaster Aqua Terra 150M Master Co-Axial Chronometer Ladies 38.5mm Stainless Steel White Mother of Pearl Dial Diamond Index Steel Bracelet 231.10.39.21.55.002 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most versatile and respected watches in the modern Omega catalogue, bridging the gap between a true sport diver's sensibility and the polished grammar of a dress watch. Launched as an evolution of the legendary Seamaster family, the Aqua Terra line takes its name from its dual personality—equally at home on water and land—and has accumulated a devoted following among collectors and everyday wearers who refuse to choose between capability and elegance. Reference 231.10.39.21.55.002 represents the ladies' interpretation of that philosophy at its most refined.

At 38.5mm in diameter, the stainless steel case of this Aqua Terra occupies a sweet spot that wears with authority on a broader range of wrists without sacrificing the substantial, quality feel that Omega is known for. The case finishing blends brushed and polished surfaces in Omega's signature style, catching light from multiple angles and lending the watch a sense of depth even before the dial is considered. The stainless steel bezel frames the dial cleanly, adding structure without visual clutter.

The dial is the undeniable centerpiece of ref. 231.10.39.21.55.002. White mother of pearl is one of the most demanding dial materials to work with: each piece of shell is cut from a natural source, meaning no two dials are ever precisely identical. The iridescent, shifting play of light across the surface gives the watch a living, organic quality that no lacquer or enamel can fully replicate. Diamond indices replace the applied hour markers found on steel-dialed variants, elevating this reference firmly into luxury territory while maintaining the clean horizontal teak-pattern lines that are an Aqua Terra hallmark.

Powering the watch is Omega's Master Co-Axial movement, a calibre that carries the brand's proprietary Co-Axial escapement—reducing friction and the need for lubrication compared with a traditional lever escapement—and is certified to Master Chronometer standards by METAS. This certification requires the movement to pass eight stringent tests, including anti-magnetic resistance to fields of 15,000 gauss, positional accuracy, and water resistance verification. For the owner, that translates to a timepiece that is demonstrably more resistant to the electromagnetic fields of everyday modern life than a standard chronometer.

On the wrist, the combination of the mother of pearl dial, diamond indices, and the flowing lines of the steel bracelet creates an effect that is simultaneously sporty and dressy—the core promise of the Aqua Terra lineage. The bracelet's mix of brushed centre links and polished outer links echoes the case finishing, tying the entire package together with considered attention to detail. Whether paired with a tailored blazer or resort wear, this watch transitions effortlessly.
