The Omega Constellation Co‑Axial Master Chronometer Ref. 131.33.41.21.06.001 is a refined and technically advanced expression of modern luxury, housed in a 41mm stainless steel case with a sleek 14mm profile . Its striking silver silk‑embossed dial—a subtle nod to vintage Constellation models—is framed by a polished black ceramic bezel with Roman numerals crafted from Omega’s proprietary Liquidmetal™, ensuring exceptional scratch resistance and a contemporary aesthetic . The elegant, blackened hands, Omega logo, and faceted indexes provide a cohesive and legible display, complemented by a practical date window at 6 o’clock . At its heart beats the in‑house Omega Master Chronometer Calibre 8900, certified by METAS for the highest standards of precision, chronometric performance, and magnetic resistance up to 15,000 gauss . This self‑winding Co‑Axial movement delivers a robust 60‑hour power reserve and is visible through the domed sapphire crystal exhibition caseback, showcasing Omega’s commitment to both art and engineering . Paired with a comfortable black rubber‑lined leather strap and secured by a steel deployant clasp, this 41mm timepiece offers 50 metres of water resistance and a versatile, contemporary presence on the wrist . A perfect balance of heritage design cues, cutting-edge technology, and everyday wearability for the discerning collector. Key specifications: 41mm stainless steel case; black ceramic bezel; silver silk-embossed dial; Omega Calibre 8900 automatic movement; 60‑hour power reserve; black leather strap with rubber lining; 50m water resistance; sapphire crystal front and exhibition back .
