A true icon among chronographs, the OMEGA Speedmaster Moonwatch Professional continues to honor its lunar legacy with the perfect blend of heritage and modern performance. This certified pre-owned 2025 example, reference 310.30.42.50.01.001, is in like-new condition and is sold with its complete original set of accessories.
Crafted in stainless steel, the watch features a 42 mm case, black step dial, and applied OMEGA logo, paired with a sapphire crystal on both the front and caseback. This version preserves the unmistakable look of the Moonwatch while offering modern-day robustness and a clear view of the movement.
Powering the watch is the manual-winding OMEGA Co-Axial Master Chronometer Calibre 3861, certified by METAS and resistant to magnetic fields up to 15,000 gauss. It offers a 50-hour power reserve, improved precision, and exceptional reliability—making it one of the most technically advanced hand-wound movements on the market.
The iconic black dial features luminous baton markers and the classic tri-compax layout with small seconds and chronograph functions. The engraved tachymeter bezel, made from black anodized aluminum, is perfect for timing speeds—a nod to its racing origins.
This certified pre-owned Moonwatch is delivered with its original OMEGA presentation box, Master Chronometer and international warranty cards, pictogram card, manual, and branded accessories (NATO strap, tool, loupe, etc.).
Perfect for enthusiasts, collectors, or first-time buyers, the OMEGA Speedmaster Professional Ref. 310.30.42.50.01.001 remains a must-have in any serious watch collection.
