Seamaster Aqua Terra 150M Co-Axial Master Chronometer 38

The Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer 38 in reference 220.10.38.20.03.001 pairs a 38 mm stainless steel case with a distinctive blue teak-pattern dial, striking a balance between sport utility and dressy versatility. Calibre 8800 powers the watch, bringing METAS-certified Master Chronometer status and resistance to magnetic fields of up to 15,000 gauss. The result is a mid-size Aqua Terra that appeals equally to collectors seeking everyday wearability and those drawn to Omega's modern movement architecture.

The Aqua Terra line was conceived as a refined, land-and-sea companion within the broader Seamaster family, distinguished by its teak-pattern dial — a nod to the teak decking of classic sailing yachts. The 38 mm variant in its current generation was introduced in 2017 alongside Omega's rollout of the Co-Axial Master Chronometer standard, which replaced the earlier Co-Axial Chronometer certification across much of the Seamaster range. Calibre 8800, a bi-directional self-winding movement co-developed with the Swiss Federal Institute of Metrology (METAS), marked a significant step forward in anti-magnetic and precision standards for the line. The reference has remained in continuous production, cementing its place as a core pillar of the modern Aqua Terra catalogue.
