The Omega Seamaster Aqua Terra 150M Master Chronometer Ref. 220.12.41.21.01.001 is a refined synthesis of maritime elegance and cutting-edge Swiss engineering, presented here on its factory black rubber strap with an integrated steel deployant clasp for a modern, comfortable fit . Its symmetrical 41 mm stainless steel case houses a striking black dial distinguished by the signature horizontal “teak” pattern —a design inspired by the wooden decks of luxury sailboats, evoking a deep connection to the sea . The dial is framed with rhodium-plated hands and indexes filled with white Super-LumiNova, ensuring optimal readability in any light, while a practical date window sits at 6 o’clock, preserving the dial’s elegant symmetry . At its heart is the Omega Master Chronometer Calibre 8900, a self-winding Co‑Axial movement certified by METAS for exceptional precision, chronometric performance, and magnetic resistance up to 15,000 gauss, delivering a robust 60-hour power reserve . The movement is visible through the wave-edged sapphire crystal exhibition caseback, showcasing Omega’s commitment to haute horlogerie finishing . This configuration is completed with a structured black rubber strap featuring a grey lining and a stainless steel link that integrates it seamlessly to the case, secured by a steel deployant clasp for both comfort and a sporty, cohesive aesthetic . Water‑resistant to 150 meters, this 41 mm Aqua Terra transitions effortlessly from a formal occasion to a weekend pursuit, offering discerning collectors the perfect balance of timeless design, innovative technology, and everyday versatility. Key specifications: 41 mm stainless steel case; black teak-pattern dial; Omega Calibre 8900 automatic Master Chronometer movement; 60-hour power reserve; black rubber strap with steel deployant clasp; 150m water resistance; sapphire crystal front and exhibition back.
