Launched in 2025, the Omega Seamaster Aqua Terra 150M 30 mm 220.55.30.20.61.001 presents an opulent take on the Aqua Terra concept, showcasing the brand's nautical heritage through its entirely gold build and diamond accents. With a case size of 30.00 mm made of 18 k Sedna™ Gold, it features a sleek polished finish and a bezel encrusted with 46 diamonds. The watch is protected by a sapphire crystal that has anti-reflective treatment on both surfaces and boasts a wave-pattern screw-in caseback, ensuring water resistance up to 150 meters. Its striking burgundy sun-brushed dial, enhanced with tinted lacquer, is adorned with 11 diamond hour markers and a date window positioned at the 6 o'clock mark. The hands and applied hour markers are also fashioned from 18 k Sedna™ Gold, with the hands treated with white Super-LumiNova for a luminous blue glow. At its heart lies the Omega Co-Axial Master Chronometer Caliber 8751, a self-winding mechanical movement verified by METAS, which operates at 25,200 vibrations per hour (3.5 Hz), offers about 48 hours of power reserve, and incorporates features like a Co-Axial escapement, a free-sprung balance with a silicon balance spring, automatic bidirectional winding, and magnetic resistance up to 15,000 gauss. Completing the luxurious appearance, the timepiece comes with a matching integrated bracelet made of 18 k Sedna™ Gold, designed with rounded polished and brushed links, fastened by a butterfly folding clasp that includes Omega's comfort-adjustment mechanism.
