Omega Seamaster Aqua Terra 150M Co-Axial Chronometer Annual Calendar 43mm Stainless Steel Black Dial Alligator Leather Strap 231.13.43.22.01.002 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most versatile and enduring references in Omega's modern catalogue, sitting at the intersection of the brand's celebrated diving heritage and its tradition of refined dress watchmaking. The Aqua Terra line was introduced to give wearers a water-resistant timepiece polished enough for the boardroom yet robust enough for an afternoon on the water, and reference 231.13.43.22.01.002 represents one of the most sophisticated expressions of that philosophy, pairing the desirable annual calendar complication with Omega's Co-Axial Chronometer movement standard.

At 43mm in stainless steel, this Aqua Terra commands immediate wrist presence without sacrificing elegance. The case is crafted from polished and brushed stainless steel, giving it a dual character that catches the light in formal settings while remaining understated enough for daily wear. The stainless steel bezel frames the dial cleanly, allowing the architecture of the watch to remain focused and uncluttered.

The black index dial is a study in legibility and restraint. Index hour markers sit with precision against the dark background, ensuring effortless time reading in a wide range of lighting conditions. The "teak concept" horizontal striping that is a hallmark of the Aqua Terra family adds subtle texture and depth to the dial, evoking the wooden decks of classic sailing yachts and reinforcing the watch's maritime identity without resorting to overt nautical clichés.

What elevates this particular reference above a standard three-hand Aqua Terra is the annual calendar complication integrated into the movement. An annual calendar distinguishes between months of 30 and 31 days automatically, requiring only a single correction at the end of February each year. Powered by Omega's Co-Axial Chronometer movement, this watch benefits from the brand's proprietary Co-Axial escapement technology, which reduces friction, improves long-term rate stability, and extends the intervals between servicing compared with a conventional lever escapement. Chronometer certification by COSC confirms the movement meets strict precision standards.

The alligator leather strap completes the watch's dual personality perfectly. Where a bracelet might push this reference toward sport territory, the supple alligator leather grounds it firmly in the world of refined horology, making it equally at home at a business dinner or a weekend regatta. The contrast between the formal strap and the 150-meter water resistance rating encapsulates exactly what the Aqua Terra was designed to achieve.
