We are pleased to present this Omega Speedmaster Professional Moonwatch, reference 310.30.42.50.04.001, featuring the striking white step dial with black accents. This model pairs the iconic Speedmaster design with the modern Master Chronometer–certified Caliber 3861, offering exceptional accuracy, anti-magnetic performance, and a smooth manual-wind experience. The watch comes on the updated stainless-steel bracelet with its comfortable taper and solid clasp. The white dial gives this Moonwatch a fresh, contemporary look while preserving the heritage that makes the Speedmaster so collectible. The condition of this watch is good, with the exception of superficial scratching throughout the case and bracelet. This watch will ship with an OMEGA outer box, inner display case with built-in travel case, dust cloth, OMEGA Speedmaster Moonwatch book, The Essential Guide, International Warranty card, Pictograms card, and Master Chronometer card (dated in March 2025). This piece has a Sapphire crystal and caseback.
