Omega's future is history

Speedmaster Moonwatch 321 Stainless Steel is equipped with a new Calibre 321.

The 1960s rounded off momentously with Nasa's Apollo 11 mission.

On July 20, 1969, astronauts Neil Armstong and Buzz Aldrin landed the lunar module Eagle and took man's first steps on the Moon, while Michael Collins remained in the command module Columbia.

Omega celebrates the 51st anniversary of the historic lunar landing with a new Speedmaster Moonwatch driven by a recreation of the space-voyaging Calibre 321.

Dating back to 1949, the original movement powered Omega's watches until 1968. Having passed all of Nasa's strict tests, the Calibre 321 beating inside a Speedmaster was qualified for manned missions in 1965. ­Subsequently, Speedmaster Professional models, equipped with the manual-winding chronograph movement with column wheel mechanism, accompanied astronauts on the Mercury, Gemini and Apollo programmes, including the defining Apollo 11 Moon landing.

Not only did it power the first watch worn on the Moon, but it also returned for all six lunar landings -- including the Apollo 17 mission in 1972, when Commander Eugene Cernan left the last footprints.

In recent years, Omega has revisited the Calibre 321, and its team of historians, researchers and movement developers as well as craftsmen and watchmakers has brought it back to life.

To reconstruct the movement as accurately as possible, tomography digital scanning was used to examine the mechanism of the Speedmaster Professional worn by Cernan on the Apollo 17 mission.

At its headquarters in Bienne, Switzerland, a workshop is dedicated to recreating the new movement.

The 2019 version of the Calibre 321 is revealed through the sapphire crystal caseback of the Speedmaster Moonwatch 321 Stainless Steel.

This new Moonwatch further celebrates space exploration as its 39.7mm case recalls a model worn in America's first spacewalk in 1965.

The design also features a bezel ring in polished black ceramic, a tachymeter scale in white enamel, as well as the iconic "Dot Over Ninety". Gracing the black dial are the familiar Moonwatch hands, along with a vintage Omega logo.
