About this watch

The Omega Seamaster Aqua Terra 150M 30 mm 220.10.30.20.09.001 debuted in 2025 as part of the women’s Aqua Terra line, offering the maritime design codes of the collection in a compact format. The watch features a 30.00 mm stainless-steel case, with a symmetrical profile, polished surfaces, and a screw-in caseback decorated with a wave-edged pattern. It is fitted with a domed sapphire crystal with anti-reflective treatment on both sides and provides water resistance to 150 meters. The sandstone-colored dial is sun-brushed and tinted with lacquer, displaying 11 applied boat-hull-shaped hour markers and a circular date window at 6 o’clock. The faceted hands and indexes are made of 18 k white gold, filled with white Super-LumiNova that emits a blue glow. Powering the watch is the Omega Co-Axial Master Chronometer caliber 8750, a self-winding movement officially certified by METAS. It runs at 25 200 vph (3.5 Hz) and offers a power reserve of approximately 48 hours. The movement features a Co-Axial escapement, free-sprung balance with silicon balance spring, and resistance to magnetic fields up to 15 000 gauss, with automatic winding in both directions. The watch is fitted with an integrated stainless-steel bracelet composed of rounded polished-brushed links, secured by a butterfly folding clasp with Omega’s comfort-adjustment system.
