Omega Seamaster Aqua Terra 150M Master Co-Axial SS Blue Dial

Introduced in Omega's 2017 update to the Seamaster Aqua Terra line, reference 220.12.38.20.03.001 is a straightforward, well-proportioned take on the everyday luxury sports watch. The 38 mm stainless steel case wears easily on a wide range of wrists and keeps the Aqua Terra's nautical design language intact. On this example, the blue dial features the collection's teak-inspired pattern and applied hour markers, giving the watch a crisp, modern look without pushing it too far from the model's more classic roots. Inside is the automatic Omega Master Co-Axial caliber 8800, a movement known for strong daily reliability, chronometer-grade accuracy, and resistance to magnetic fields. As a Master Chronometer model, it reflects Omega's move in the late 2010s toward combining traditional mechanical watchmaking with more rigorous performance testing. The layout stays clean: central hours, minutes, and seconds, a date display, and a case size that feels balanced rather than oversized. With 150 meters of water resistance, this Aqua Terra works as a true all-purpose sports watch, not simply a dress watch with sporty styling. It was not made as a limited edition or for a specific market, which makes it an especially representative Aqua Terra reference from the period. For collectors and first-time Omega buyers alike, 220.12.38.20.03.001 offers a strong mix of everyday wearability, restrained design, and the proven caliber 8800.
