Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer 34mm Steel Sedna Gold Grey Dial Diamond Hour Markers Steel Sedna Gold Bracelet 220.20.34.20.59.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most versatile and enduring sport-dress watches in modern horology, and reference 220.20.34.20.59.001 represents the line at its most refined. Introduced as part of Omega's broader Seamaster family—a lineage that stretches back to 1948—the Aqua Terra was conceived as a watch equally at home on a yacht deck, in a boardroom, or at a formal dinner. The 150M designation speaks to its serious water-resistance credentials, while the clean, horizontal-stripe dial pattern inspired by teak yacht decks has become one of the most recognizable design signatures in the segment.

At 34mm, this particular Aqua Terra is sized for a versatile, elegant fit on a wide range of wrists. Rather than the sporting boldness of larger contemporary cases, the 34mm diameter leans into the watch's dress sensibility, offering a sleek, understated profile that sits beautifully beneath a shirt cuff. The stainless steel case is beautifully complemented by Omega's Sedna gold—a proprietary rose-gold alloy developed in-house that is engineered to retain its warm, rich color over decades of wear, resisting the fading that can affect lesser gold alloys.

The grey dial is the visual centerpiece of this reference. Its sophisticated neutral tone reads as both contemporary and timeless, and the diamond hour markers introduce a level of luxury finishing rarely found in a watch that is equally built for everyday wear. Each diamond is precisely set to catch and refract light, adding brilliance without ostentation. The Sedna gold bezel frames the dial with a continuous warm glow, tying together the two-tone steel and Sedna gold bracelet into a cohesive and unmistakably premium aesthetic.

Powering the watch is Omega's Co-Axial Master Chronometer movement, a technology platform that represents the current pinnacle of the brand's watchmaking. The Co-Axial escapement, co-developed with independent watchmaker George Daniels, dramatically reduces friction and wear on the escapement components, contributing to long-term precision and reduced service intervals compared with traditional lever escapements. Master Chronometer certification, granted by the Swiss Federal Institute of Metrology (METAS), means the movement has passed a rigorous battery of tests covering accuracy, magnetic resistance, and water resistance, confirming it as one of the most thoroughly validated movements in production watchmaking.
