Pre-owned Omega Seamaster Aqua Terra 150M ref. 220.20.38.20.03.001 (2026) is made of stainless steel and 18k Sedna™ gold, Omega’s proprietary rose gold alloy, creating a warm two-tone aesthetic that pairs beautifully with the vibrant blue waved dial. The dial features a date display at 6 o’clock for a clean, symmetrical layout, while the distinctive sailboat hull-shaped indexes and dagger hands are fashioned from matching Sedna™ gold. Completing the watch is the integrated two-tone bracelet, which gives the Aqua Terra its signature streamlined profile. Beneath the dial beats Omega’s Master Chronometer caliber 8800, a METAS-certified Co-Axial movement with exceptional precision, magnetic resistance, and everyday reliability.
