Seamaster Aqua Terra 41.5mm 18K Sedna™ Gold Bezel | Ref. 231.23.42.21.06.001 | 2014 Mint Full Set

The Story

The Omega Seamaster Aqua Terra 150M stands as one of the most versatile luxury sports watches in modern horology, effortlessly bridging the gap between maritime utility and bespoke dress elegance. While modern steel references offer a classic aesthetic, reference 231.23.42.21.06.001 elevates the line into executive territory through Omega's proprietary 18K Sedna™ Gold—a unique rose gold alloy blending gold, copper, and palladium to ensure a rich, fade-resistant reddish hue. Now officially discontinued, this bi-color execution pairs precious warm metal accents with an industrial slate-grey teak dial, tailored specifically for the collector who demands distinct, under-the-radar luxury with historical pedigree.

The Craft: 18K Sedna™ Gold Geometry & Twin-Barrel Calibre 8500

The 41.5mm case presents a masterclass in material combination, pairing a finely finished stainless steel mid-case with a solid 18K Sedna™ Gold bezel and winding crown. The lyre-lug geometry alternates between satin-brushed profiles and mirror-polished facets.

The slate-grey dial features the iconic vertical "Teak-Concept" pattern, drawing direct aesthetic inspiration from the wooden decks of luxury yachts. The dial changes dynamically under different lighting angles, highlighted by 18K Sedna™ Gold applied hour markers, matching arrowhead hands, and a framed date window at 3 o'clock.

Turn the watch over to admire the mechanical movement through the sapphire exhibition caseback: the In-house Co-Axial Calibre 8500. Built with twin barrels mounted in series, it provides a smooth 60-hour power reserve and chronometer-certified timekeeping stability. Engineered for long-term mechanical endurance, it features a free-sprung balance and silicon hairspring for anti-magnetic reliability, supported by a screw-down crown for a professional rating of 150 meters (500 feet) of water resistance.
