Speedmaster Moonwatch Professional Sapphire Sandwich 42mm | Ref. 310.30.42.50.01.002 | 2025 Full Set

The Story

The Omega Speedmaster Professional Moonwatch is universally recognized as the single most iconic chronograph in horological history. Flight-qualified by NASA in 1965 for all manned space missions and worn on the lunar surface during Apollo 11 in July 1969, the Moonwatch remains an unshakeable pillar of human exploration. Reference 310.30.42.50.01.002 represents the definitive "Sapphire Sandwich" execution of the modern era. By pairing scratch-resistant front and exhibition sapphire crystals with the upgraded Master Chronometer engine, Omega created the ultimate everyday luxury chronograph tailored for the collector who demands NASA pedigree combined with uninterrupted views of haute horlogerie finishing.

The Craft: 4th-Gen Case Geometry & Master Chronometer Calibre 3861

The 42mm stainless steel case draws direct architectural inspiration from the 4th-generation Moonwatch worn on the Moon (ST 105.012), featuring asymmetrical twisted lyre lugs with integrated crown and pusher protection. The black anodized aluminum bezel insert features the celebrated historical "Dot Over 90" (DON) and a diagonal dot to 70 marker.

The matte black step dial provides optimal legibility, featuring a recessed minute track, triple chronograph registers, and an applied metallic Omega logo exclusive to the Sapphire Sandwich configuration.

Turn the watch over to admire the mechanical mastery through the sapphire exhibition caseback: the In-house Co-Axial Master Chronometer Calibre 3861. This manual-wind chronograph movement incorporates a Co-Axial escapement, silicon Si14 balance spring, and hacking seconds functionality. Certified by METAS (the Swiss Federal Institute of Metrology), it provides chronometric precision of 0/+5 seconds per day, complete immunity to magnetic fields exceeding 15,000 gauss, and a 50-hour power reserve. The movement is finished with Geneva waves, circular graining, and rhodium-plated bridges.
