Omega Speedmaster Moonwatch Professional Hesalite

About This Watch

The Omega Speedmaster Moonwatch Professional with Hesalite crystal is the direct descendant of the watch worn on the Moon during the Apollo 11 mission in 1969. Updated in 2021 with the Master Chronometer-certified caliber 3861, this model retains the iconic Hesalite crystal that was specified on the original flight-qualified models. The 3861 movement represents a significant upgrade over the legendary 1861, offering METAS certification with resistance to magnetic fields up to 15,000 gauss. The asymmetric case design, stepped dial with applied indices, and distinctive dot-over-ninety bezel marking remain faithful to the heritage of the original Moonwatch. The Hesalite crystal gives the dial a warm, vintage character that many collectors prefer over sapphire, though it is more prone to scratching. At 42mm with a 47mm lug-to-lug, it wears comfortably on most wrists. The manual-winding movement with 50 hours of power reserve connects the wearer to a tradition of hand-wound chronographs. This is not merely a watch — it is a piece of space exploration history, the only timepiece flight-qualified by NASA for all manned space missions.
