Seamaster Aqua Terra 38.5mm Blue Teak Dial | Ref. 231.10.39.21.03.002 | 2019 Mint Full Set (Serviced)

The Story

The Omega Seamaster Aqua Terra 150M stands as the definitive standard for the true "one-watch collection," mastering both maritime capability and tailored dress sophistication. Reference 231.10.39.21.03.002 represents what purists regard as the golden proportion of modern Aqua Terra collecting: a 38.5mm case dimension combined with the iconic vertical "Teak Concept" dial. Finished in an electric sun-brushed blue inspired by luxury yacht decking, this discontinued generation features the advanced Master Co-Axial Calibre 8500, delivering mid-century proportions with cutting-edge magnetic immunity.

The Craft: 38.5mm Steel Geometry & Master Co-Axial Calibre 8500

The 38.5mm stainless steel case features Omega's signature twisted lyre lugs, combining satin-brushed case flanks with mirror-polished bevels and a polished bezel.

The blue vertical teak dial shifts dynamically under light, transitioning from vivid royal blue in direct sunlight to deep midnight navy in low light. It features diamond-polished, rhodium-plated triangular hour indices, broad arrowhead hands coated with Super-LumiNova, and a clean date window at 3 o'clock.

Turn the watch over to admire the mechanical architecture through the sapphire exhibition caseback: the In-house Omega Master Co-Axial Calibre 8500. Built to withstand magnetic fields exceeding 15,000 gauss, this automatic engine utilizes twin barrels mounted in series to provide a steady 60-hour power reserve. It features an independently adjustable jumping hour hand for easy time-zone travel, adorned with Arabesque Geneva waves and circular graining. Supported by a screw-down crown, it carried an original factory water resistance rating of 150 meters (500 feet).
