Key Specs
History

In 1957, Omega released the Speedmaster as a racing chronograph. Eight years later, NASA put it through a battery of extreme tests — temperature, humidity, vacuum, shock, vibration, acceleration — and in 1965 certified it as the official watch for all manned space missions.

On July 20, 1969, Buzz Aldrin wore his Speedmaster on the surface of the Moon. No other watch has been to the Moon. That fact has never stopped mattering to anyone who cares about watches.

The Speedmaster's production history across our inventory is rich: the manual-wind Professional (ref 145.022 from 1969 itself), the Reduced automatic (3510.5, 3511.5, 3511.8 with date), the Triple Calendar series (3521, 3523.3), the Michael Schumacher limited editions (3810.12, 3518.5), and the AC Milan and Schumacher World Champion 2000 editions. Each variant was built on the same essential chassis — the 39mm steel case, the tachymeter bezel — and each one lands somewhere on the continuum between racing instrument and artifact of human achievement.
