Seamaster Aqua Terra 38.5mm Black Teak Dial | Ref. 231.10.39.21.01.001 | 2011 Mint Full Set (Serviced)

The Story

The Omega Seamaster Aqua Terra 150M has long represented the apex of the "Go Anywhere, Do Anything" (GADA) philosophy. Reference 231.10.39.21.01.001 captures what many collectors consider the golden ratio of the lineage: a 38.5mm case dimension paired with the purist-preferred vertical "Teak Concept" dial. Inspired by the rich wooden decking of luxury yachts, this generation features the highly desirable framed date aperture at 3 o'clock. Now discontinued and no longer in production, this reference delivers classic mid-century proportions and modern mechanical reliability.

The Craft: 38.5mm Proportions & The Co-Axial Calibre 8500 Engine

The 38.5mm stainless steel case features Omega's signature twisted lyre lugs, alternating between satin-brushed case flanks and mirror-polished bezels.

The jet black vertical teak dial shifts dynamically under light, transitioning from charcoal texture to rich gloss black. It is detailed with applied, diamond-polished rhodium-plated hour indices, broad arrowhead hands coated with Super-LumiNova, and an applied white gold date window frame at 3 o'clock.

Turn the watch over to admire the mechanical architecture through the sapphire exhibition caseback: the Manufacture Omega Co-Axial Calibre 8500. Built with twin barrels mounted in series, this automatic engine delivers a steady 60-hour power reserve and features an independently adjustable jumping hour hand—allowing swift timezone adjustments without interrupting the balance wheel. Decorated with Arabesque Geneva waves and circular graining, the watch is supported by a screw-down crown with an original factory water resistance rating of 150 meters (500 feet).
