The Omega Speedmaster Moonwatch Professional Ref. 310.30.42.50.01.004 is a compelling contemporary reinterpretation of the legendary lunar chronograph, often celebrated for its distinctive “reverse panda” aesthetic . Housed in a 42 mm polished and brushed stainless steel case and secured by a matching five-link bracelet, this 2026 reference draws inspiration from the fourth-generation Speedmaster worn on the moon while introducing modern materials and a striking new dial configuration . The design features a black varnished and lacquered double-plate step dial, which provides an exceptionally deep and intense backdrop, achieved through more than 20 layers of lacquer . This is complemented by white varnished and lacquered subdials set within rhodium-plated frames, offering the high-contrast readability that defines the chronograph . Adding to its robust appeal, the fixed bezel is crafted from scratch-resistant black ceramic with a white enamel tachymetric scale, preserving the famous “dot over 90” marking that is a cherished hallmark of Speedmaster lore . At its heart beats the state-of-the-art Omega Co-Axial Master Chronometer Calibre 3861, a manual-winding movement visible through the sapphire crystal exhibition caseback . Certified by METAS, this calibre offers magnetic resistance up to 15,000 gauss, a 50-hour power reserve, and the precision that honours its lunar legacy .
