Omega Seamaster Aqua Terra 150M Master Co-Axial 30 Sedna Gold / Linen / Bracelet

About this watch

The OMEGA Seamaster Aqua Terra [REFERENCE] debuted in 2025 as a full-gold 30mm model within the Aqua Terra collection with a Beige dial. This version features a symmetrical case crafted entirely from 18K Sedna Gold, with polished surfaces and a screw-in case back bearing OMEGA’s signature wave-edged design. The Beige dial is sun-brushed, PVD-treated, and lacquered, with a circular date window at 6 o’clock. Eleven boat hull-shaped hour markers and faceted hands are made of 18K Sedna Gold and filled with white Super-LumiNova that emits a blue glow. The redesigned minute hand tapers to a fine point, reinforcing the watch’s refined proportions. It is powered by the automatic 8750, a METAS-certified Master Chronometer movement with a 48-hour power reserve and resistance to magnetic fields up to 15,000 gauss. The watch is worn on an integrated 18K Sedna Gold bracelet with polished-brushed links, secured by a butterfly clasp and fitted with OMEGA’s comfort-adjustment system.
