Icon
A symbol of human ingenuity
More than a measuring instrument, the Moonwatch represents trust in mechanical design when every second matters beyond Earth.
On the Moon
In July 1969, the Speedmaster kept time on Apollo 11 astronauts’ wrists. Since then, its presence in space has become part of both technical and popular culture.
Evolution with respect
Generations of calibers preserve the original spirit: the legacy of the 321 and the precision of today’s standard, with METAS Master Chronometer certification.
Heritage
The watch that went to space
NASA put several chronographs through extreme trials. The Speedmaster was the only one to pass the full protocol, earning its official assignment for the U.S. crewed space program.
Buzz Aldrin wore his Speedmaster during the lunar descent; Neil Armstrong left his in the module as backup for electronic systems — a detail that reinforces the Moonwatch’s role as a human fallback instrument.
“Moonwatch” isn’t marketing
It’s the nickname used by both the community and Omega for the Professional tied to the Apollo program.
From orbit to museums
Examples flew in Gemini, Apollo, and Skylab; many are preserved as heritage pieces of human exploration.
