Launched in 2025, the Omega Seamaster Aqua Terra 150M 30 mm 220.20.30.20.10.002 is a striking addition to the Aqua Terra series, showcasing a nautical theme enhanced by a sophisticated bi-metal design. The timepiece features a 30.00 mm case crafted from both stainless steel and 18 k Sedna™ Gold, characterized by its symmetrical polished exterior and a screw-in caseback adorned with a wave-edge pattern. Visibility is excellent in all conditions, thanks to the domed sapphire crystal treated with anti-reflective coating on both sides. This model offers water resistance up to 150 meters.

The dial is a stunning pine-green, treated with a sun-brushed finish and tinted lacquer, and includes 11 boat-hull-shaped hour markers along with a date window positioned at 6 o'clock. The hands and indexes, made from 18 k Sedna™ Gold, are topped with white Super-LumiNova, providing a blue glow in low light. At its heart lies the Omega Co-Axial Master Chronometer caliber 8750, a self-winding mechanical movement recognized by METAS for its precision. It operates at a frequency of 25,200 vibrations per hour (3.5 Hz) and offers an approximate power reserve of 48 hours, incorporating advanced features such as a Co-Axial escapement, a free-sprung balance with silicon balance spring, and bidirectional automatic winding, along with impressive resistance to magnetic interference of up to 15,000 gauss. Complementing the watch is a bracelet made from a combination of stainless steel and 18 k Sedna™ Gold links, rounded for comfort and secured with a butterfly folding clasp that includes Omega's comfort-adjustment system.
