Overview
The Omega Speedmaster Moonwatch Professional ref. 310.32.42.50.01.002 represents the most technically advanced iteration of the watch that accompanied NASA astronauts to the lunar surface. Introduced in 2021, it pairs the storied 42 mm stainless steel case and black dial with the newly developed calibre 3861, elevating the Moonwatch to METAS-certified Master Chronometer status for the first time. The result is a timepiece that honours more than six decades of horological and spaceflight heritage while meeting the most rigorous modern standards for accuracy and magnetic resistance.
History
The Speedmaster line traces its origins to 1957, when Omega introduced a chronograph aimed at motorsport and professional use. Its trajectory changed permanently after NASA selected it as flight-qualified equipment in 1965, and it was subsequently worn on every crewed lunar landing mission beginning in 1969. The Professional designation has since become synonymous with that space-age legacy, and the reference 310.32.42.50.01.002 marks the line's most significant mechanical update in decades, replacing the long-serving calibre 321 and 1861 lineage with the modern calibre 3861 movement architecture.
Notable points
- Calibre 3861 is a column-wheel, co-axial escapement movement certified to METAS Master Chronometer standards, guaranteeing accuracy of 0/+5 seconds per day and resistance to magnetic fields exceeding 15,000 gauss.
- The 42 mm stainless steel case retains the traditional Moonwatch silhouette — including the asymmetric case, pump pushers, and hesalite crystal on the standard configuration — preserving visual continuity with the original NASA-qualified references.
- The black dial carries the classic 'Moonwatch' layout with applied hour markers, three white subsidiary registers, and the tachymeter scale on the bezel, maintaining the aesthetic established in the 1960s.
- Introduced in 2021, this reference marked a generational update to the Moonwatch, bringing a free-sprung balance wheel with variable inertia and an improved co-axial escapement for enhanced long-term reliability.
- The Speedmaster Moonwatch Professional remains one of the few mechanical chronographs to hold both an active spaceflight heritage and a current METAS certification, bridging historical significance with contemporary watchmaking standards.
