The Omega Seamaster Aqua Terra 150M 30 mm (Ref. 220.55.30.20.61.001) debuted in 2025 as one of the most opulent interpretations of the Aqua Terra collection. This model embodies Omega’s maritime heritage through a luxurious design rendered entirely in 18K Sedna™ Gold, combining elegance, technical innovation, and exceptional finishing. The 30 mm case features a symmetrical polished profile with a diamond-set bezel adorned with 46 brilliant-cut diamonds, enhancing its refined aesthetic. A domed sapphire crystal with anti-reflective treatment on both sides ensures pristine clarity, while the wave-edged screw-in caseback reflects the Seamaster’s nautical roots. The watch is water-resistant to 150 meters, balancing beauty with durability. The burgundy sun-brushed dial, colored with tinted lacquer, is embellished with 11 diamond hour markers and a date aperture at 6 o’clock. The 18K Sedna™ Gold hands and indexes, coated with white Super-LumiNova that emits a blue glow, enhance legibility while maintaining a luxurious tone. At its heart lies the Omega Co-Axial Master Chronometer Caliber 8751, a METAS-certified self-winding movement operating at 25,200 vph (3.5 Hz) with a 48-hour power reserve and magnetic resistance up to 15,000 gauss. Completing the design, the integrated Sedna™ Gold bracelet with polished-brushed links and a butterfly clasp featuring Omega’s comfort-adjustment system delivers timeless elegance and wearing comfort.
