Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Small Seconds 38mm Stainless Steel Sedna Gold Bezel Green Dial Diamond Set Index Black Alligator Leather Strap 220.23.38.20.60.001 - BRAND NEW Omega Seamaster Aqua Terra 150M Co-Axial Master…

The Omega Seamaster Aqua Terra 150M is one of the most versatile and accomplished sport-dress watches in modern horology, and reference 220.23.38.20.60.001 represents the line at its most glamorous. Introduced under Omega's contemporary Master Chronometer generation, the Aqua Terra 150M family draws its identity from the sea — the teak-inspired "wave" pattern on earlier models evolved into the clean, open dials seen today — while offering a level of finishing and movement quality that few competitors at any price can match. This 38mm configuration is deliberately proportioned for wrists that find the larger 41mm variant overwhelming, and it wears with the confident subtlety of a watch designed to be noticed for its quality rather than its size.

The dial of reference 220.23.38.20.60.001 is finished in a deep, saturated green that has become one of the most sought-after colours in contemporary watchmaking. Rather than simple applied indices, Omega has set the hour markers with diamonds, catching light at every angle and introducing a level of jewellery-grade refinement that is unusual in a watch that retains genuine water-resistant sport credentials. The small seconds sub-dial, a detail that underscores the mechanical complexity within, sits cleanly against the green ground and reinforces the watch's horological seriousness.

Framing that dial is a bezel crafted in Sedna gold, Omega's proprietary rose-gold alloy formulated to resist fading and maintain its warm, rosy hue over decades of wear. Sedna gold is an in-house Omega innovation — a blend of gold, copper, and palladium — and its presence on this reference immediately signals that this is not a standard steel sports watch. The contrast between the cool stainless steel case, the warm Sedna gold bezel, and the rich green dial creates a colour palette that is both contemporary and genuinely luxurious.

Powering the watch is Omega's Co-Axial Master Chronometer movement, a designation that carries two distinct layers of meaning. The Co-Axial escapement, developed with George Daniels, reduces friction and the need for lubrication in the escapement, contributing to long-term accuracy and reduced service intervals. Master Chronometer certification means the calibre has passed METAS testing — an eight-test protocol administered by the Swiss Federal Institute of Metrology — verifying precision, magnetic resistance, and performance across multiple positional readings. The small seconds complication gives the movement an additional visual and mechanical dimension that distinguishes this reference from the more common central-seconds variants in the Aqua Terra family.

The watch is presented on a black alligator leather strap, a choice that amplifies its dress sensibility without sacrificing comfort. Alligator leather pairs naturally with formal and smart-casual attire, and on a 38mm case it creates a sleek, slim wrist profile that slips easily beneath a shirt cuff. This is a watch that transitions from a business setting to an evening out without a change of strap required.
