Omega Seamaster Aqua Terra 150M Co-Axial Chronometer Annual Calendar 38.5mm Stainless Steel Silver Dial Steel Bracelet 231.10.39.22.02.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M Co-Axial Chronometer Annual Calendar reference 231.10.39.22.02.001 represents one of the most compelling intersections of everyday wearability and genuine horological sophistication in Omega's modern catalog. Introduced as part of the Aqua Terra family — itself a descendant of the legendary Seamaster lineage that stretches back to 1948 — the Aqua Terra line was conceived to bridge the gap between a serious dive-heritage sports watch and a refined, boardroom-ready timepiece. The annual calendar complication elevates this particular reference further still, offering a level of calendar intelligence rarely found at this price point in the luxury watch market.

Designed around a 38.5mm stainless steel case, this Aqua Terra strikes a versatile mid-size silhouette that sits beautifully on a wide range of wrist sizes, appealing equally to those who prefer a more classic, understated diameter and to those who simply want a watch that transitions effortlessly from weekend sailing to a formal dinner. The polished and brushed finishing on the stainless steel case and matching bracelet is executed with Omega's characteristically meticulous attention to surface quality, giving the watch a presence that reads as both sporty and thoroughly dressed.

The silver dial with index hour markers is clean, legible, and unmistakably Aqua Terra in character. The horizontal "teak" pattern — a subtle striped texture referencing the wood decking of classic sailing yachts — gives the dial depth and visual interest without compromising readability. Index markers are applied with precision, catching light in a way that reinforces the watch's premium positioning. The annual calendar display integrates harmoniously into the dial layout, providing date and month information with the sort of typographic discipline that Omega's design team is known for.

At the heart of this timepiece is Omega's Co-Axial Chronometer movement, a technology that has fundamentally distinguished the brand's mechanical watches since its introduction in the late 1990s. The Co-Axial escapement dramatically reduces friction within the movement, resulting in longer service intervals and superior long-term accuracy compared to traditional lever escapements. Chronometer certification from COSC means the movement has been rigorously tested across multiple positions and temperature ranges to meet the most demanding standards of mechanical precision in the industry. The annual calendar complication adds a layer of practical utility, automatically accounting for months of 30 and 31 days and requiring only a single manual correction — at the end of February — each year.

From an investment and ownership perspective, this reference combines several attributes that discerning buyers look for: a respected in-house movement architecture, a universally flattering case size, a versatile steel bracelet that can be dressed up or down, and the reassurance of brand-new condition. The Seamaster Aqua Terra with annual calendar occupies a thoughtful niche — it is more feature-rich than a simple three-hand Aqua Terra yet far more discreet than a Grand Complications piece, making it an ideal daily companion watch for the collector who values function alongside form. Bizak & Co. is pleased to offer this watch brand new, ensuring you receive the complete manufacturer presentation and the peace of mind that comes with purchasing from a trusted luxury watch dealer.
