Overview
The Omega Speedmaster Moonwatch Professional ref. 310.30.42.50.01.001 is the current production expression of the watch that accompanied NASA astronauts to the lunar surface in 1969. Housed in a 42 mm stainless steel case and fitted with a black dial, it preserves the asymmetric case, pump pushers, and hesalite crystal that have defined the Speedmaster silhouette for decades. Beneath the dial, Omega's in-house Calibre 3861 brings METAS-certified Master Chronometer status to a movement lineage that traces directly to the original manually wound column-wheel chronograph.
History
The Speedmaster was introduced in 1957 as a sport and racing chronograph, and its association with human spaceflight began in earnest when NASA qualified it for all crewed missions in 1965. The reference 310.30.42.50.01.001 was launched in 2021, representing the most significant mechanical update to the Moonwatch in many years. The introduction of Calibre 3861 — featuring a co-axial escapement and anti-magnetic silicon balance spring — brought the storied manual-wind chronograph into the modern era of METAS certification while retaining the watch's historically faithful aesthetic.
Notable points
- Calibre 3861 is a manually wound, column-wheel chronograph movement certified to METAS Master Chronometer standards, offering resistance to magnetic fields of 15,000 gauss.
- The hesalite (acrylic) crystal on the front and sapphire caseback are a deliberate nod to the flight-qualified configuration worn on the Moon.
- The asymmetric 42 mm stainless steel case retains the pump-style chronograph pushers and the broad arrow hands that have characterised the Speedmaster since the late 1950s.
- A co-axial escapement and silicon balance spring replace the lever escapement of earlier Moonwatch calibres, improving long-term accuracy and reducing servicing frequency.
- The black stepped dial with applied indexes and the tachymeter bezel scale remain faithful to the design language established by the reference ST 105.012 of the 1960s.
