Pre-owned Omega Speedmaster Moonwatch Professional ref. 310.32.42.50.01.002 (2025) is Omega’s current Moonwatch in its purest modern form. Released as part of the 2021 Speedy update, it marked one of the most important evolutions in the model’s history since the late 1960s. This is still the watch tied to all six moon landings, still the chronograph that earned its place in NASA’s flight program, but it’s been carefully refined for today. The 42mm stainless steel case features the familiar asymmetrical profile first introduced with the 4th-generation Speedmasters worn on the moon. The black step dial, applied OMEGA logo, and that all-important dot over 90 on the anodized aluminum bezel are details longtime collectors immediately look for. It features a sapphire crystal on both the front and the caseback, giving you a view of the caliber 3861 inside. And that movement is the real upgrade. The manually wound caliber 3861 is METAS-certified and has a Co-Axial escapement. Shop OMEGA Speedmaster Collection
