About this watch

The Omega Seamaster Aqua Terra 150M 30 mm 220.55.30.20.61.001 debuted in 2025 as a luxurious interpretation of the Aqua Terra design, combining the collection’s maritime inspiration with a fully gold construction and diamond detailing. The watch features a 30.00 mm case in 18 k Sedna™ Gold, distinguished by its symmetrical polished profile and a polished bezel set with 46 diamonds. It is equipped with a sapphire crystal with anti-reflective coating on both sides and a screw-in caseback with wave-edged design. Water resistance is rated to 150 meters. The burgundy sun-brushed dial, coloured with tinted lacquer, displays 11 diamond hour markers and a circular date window at 6 o’clock. The faceted hands and applied indexes are crafted in 18 k Sedna™ Gold, while the hands are coated with white Super-LumiNova emitting a blue glow. Powering the watch is the Omega Co-Axial Master Chronometer Caliber 8751, a self-winding mechanical movement officially certified by METAS. It operates at 25 200 vph (3.5 Hz) with a power reserve of approximately 48 hours and features a Co-Axial escapement, free-sprung balance with silicon balance spring, bidirectional automatic winding, and magnetic resistance up to 15 000 gauss. The watch is fitted with an integrated 18 k Sedna™ Gold bracelet composed of rounded polished-brushed links, secured by a butterfly folding clasp with Omega’s comfort-adjustment system.
