About this watch

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