Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer 34mm Sedna Gold Diamond Bezel White Mother-of-Pearl Dial Diamond Set Index Sedna Gold Bracelet 220.55.34.20.55.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most versatile and celebrated collections in modern watchmaking, bridging the gap between a purpose-built sports watch and an elegant dress timepiece with effortless authority. Introduced as part of Omega's storied Seamaster family — a lineage that dates back to 1948 — the Aqua Terra line has long been associated with refined nautical design cues, exceptional engineering, and a broadened appeal that transcends the traditional boundaries of sport and luxury. Reference 220.55.34.20.55.001 elevates that legacy to its most opulent expression, combining precious materials, diamond setting, and Omega's highest movement certification into a single cohesive package.

The 34mm case is fashioned entirely in Sedna Gold, Omega's exclusive 18k rose-gold alloy developed in partnership with a precious-metals specialist to resist fading and retain its distinctive warm, rosy hue far longer than conventional rose gold. The case proportions at 34mm make this reference an ideal fit for smaller wrists, yet the presence and weight of solid Sedna Gold ensure it wears with the authority and gravitas one expects from a high-jewellery Omega. Every curve of the case and lug has been finished to Omega's exacting standards, alternating between polished and brushed surfaces that catch light in shifting, dramatic ways.

The bezel is set with diamonds, framing the dial in a continuous arc of brilliance that immediately signals this watch's position at the very top of the Aqua Terra hierarchy. The white mother-of-pearl dial is one of nature's most naturally iridescent materials, its organic luminosity shifting subtly with ambient light from creamy ivory to soft rose to the palest silver depending on the angle of view. Diamond-set indexes replace the standard applied markers, ensuring that every hour position glitters in concert with the bezel and contributing to a cohesive all-diamond visual narrative that is both restrained and genuinely spectacular.

Powering the watch is Omega's Co-Axial Master Chronometer movement, a designation that signals the highest level of performance, precision, and magnetic resistance available from Omega. The Co-Axial escapement, a genuine advancement in watchmaking engineering, reduces friction and wear compared to traditional lever escapements, contributing to longer service intervals and sustained accuracy over the life of the watch. Master Chronometer certification, conducted by METAS — the Swiss Federal Institute of Metrology — sets this movement to a standard that goes beyond the traditional COSC chronometer, verifying performance across multiple positions, in everyday magnetic environments, and throughout a demanding series of precision tests. The result is a movement you can trust absolutely, housed in a case worthy of its pedigree.

On the wrist, the 220.55.34.20.55.001 is an exercise in confident, feminine luxury. The Sedna Gold bracelet, matching the case in both material and finish, drapes the wrist with a satisfying warmth and weight that speaks to the quality of every component. The 34mm diameter and the refined proportions of the Aqua Terra case mean this watch stacks beautifully with bracelets or stands alone as an unambiguous centerpiece. Whether dressed for an evening event or worn as an everyday affirmation of exceptional taste, this reference performs equally well.
