The Omega Speedmaster Professional Moonwatch Steel White Dial 42mm Ref. 310.32.42.50.04.001 is a modern interpretation of the iconic chronograph that accompanied all six moon landings. Crafted in stainless steel, the 42mm asymmetrical case is inspired by the 4th-generation Speedmaster design. Its black anodized aluminum bezel features the iconic "dot over 90" detail, while the white lacquered step dial with applied indexes and Moonwatch-style hands provides a clean and striking aesthetic. Powered by the Co-Axial Master Chronometer Calibre 3861, this manual-winding movement delivers exceptional precision, magnetic resistance, and a 50-hour power reserve. The chronograph features include a small seconds sub-dial, 30-minute recorder, 12-hour recorder, and a central chronograph hand. The watch is paired with a black rubber strap, featuring a unique lunar surface pattern on the underside, and a stainless steel deployment clasp. Water-resistant to 50 meters, this Moonwatch bridges heritage and contemporary design with technical excellence.
