Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Stainless Steel Black Dial & NATO Strap 41mm 220.12.41.21.01.002 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most versatile and enduring expressions in the entire Seamaster family, a collection with roots stretching back to 1948 when Omega introduced its first water-resistant dress watch. The Aqua Terra line refined that heritage into something that bridges the worlds of sport and elegance with extraordinary grace, and reference 220.12.41.21.01.002 represents the line at its contemporary best—brand new, unacquired, and ready for decades of service.

At 41mm in stainless steel, this watch occupies an ideal case size that sits confidently on a wide range of wrist proportions without tipping into sportswear territory. The stainless steel domed bezel traces a smooth, clean arc that draws the eye inward toward the black index dial, where applied hour markers catch the light with quiet authority. The absence of a date window or busy sub-registers keeps the dial calm and legible—a deliberate design choice that speaks to confident minimalism rather than restraint born of compromise.

Powering this reference is Omega's Co-Axial Master Chronometer movement, a designation that carries real technical weight. Master Chronometer certification means the caliber has passed independent testing by METAS (the Swiss Federal Institute of Metrology) across eight demanding tests, verifying precision, magnetic resistance to fields of 15,000 gauss, and overall performance to the highest standards in the Swiss watchmaking industry. The Co-Axial escapement, developed in collaboration with independent watchmaker George Daniels, dramatically reduces friction and wear compared with a traditional lever escapement, translating to longer service intervals and sustained accuracy over the life of the watch.

The NATO strap configuration gives this particular reference a relaxed, adventurous character that pairs naturally with the Aqua Terra's nautical DNA. NATO straps are renowned for their security—the watch remains on the wrist even if a spring bar fails—and the configuration makes swapping straps straightforward, so the owner can easily dress the watch up or down. The 150-metre water resistance rating built into the Aqua Terra case means this is a watch that can genuinely accompany an active lifestyle without reservation.
