Moonwatch
A common name for the Omega Speedmaster Professional lineage associated with NASA and crewed lunar missions.
Also known as: Omega Moonwatch, Speedmaster Moonwatch
Definition
Moonwatch most commonly refers to Omega's Speedmaster Professional lineage associated with NASA's crewed space programme and the lunar landings. The name rests on a specific historical relationship: NASA qualified the Speedmaster for crewed missions, and Speedmasters were worn during Apollo lunar operations. Modern Omega products also use Moonwatch as an official collection designation, so the word can describe both the historic association and current descendants.
Why it matters
It matters because 'Moonwatch' is more specific than simply a space-themed chronograph; provenance, generation and reference determine how directly an individual watch connects to the historic NASA specification.
