About this watch

The Omega Seamaster Aqua Terra 150M 30 mm 220.10.30.20.55.001 debuted in 2025 as part of the compact Aqua Terra collection, combining the maritime design language of the Seamaster family with refined proportions and Master Chronometer performance. The watch features a 30.00 mm stainless-steel case with a symmetrical profile, polished surfaces, and a screw-in caseback with a wave-edged design. The front crystal is domed sapphire with anti-reflective coating on both sides. Water resistance is rated to 150 meters. The white mother-of-pearl dial is finished with a glossy surface and framed by 11 diamond hour markers. A circular date window sits at 6 o’clock, while the faceted hour and minute hands—together with the applied indexes—are crafted in 18 k white gold. The hands are coated 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 operates at 25 200 vph (3.5 Hz) with a power reserve of approximately 48 hours. The movement features a Co-Axial escapement, free-sprung balance with silicon balance spring, and is resistant to magnetic fields up to 15 000 gauss, with automatic winding in both directions. The watch is paired with an integrated stainless-steel bracelet composed of rounded polished-brushed links, secured by a butterfly folding clasp equipped with Omega’s comfort-adjustment system.
