The Omega Speedmaster: How a Racing Watch Became the Moonwatch

Before it became the first watch worn on the Moon, the Omega Speedmaster had to survive NASA, the vacuum of space — and one of the most extraordinary journeys in watchmaking history.

Today, the connection between Omega and space exploration feels almost inevitable.

The Speedmaster is the Moonwatch. Its black dial, three-register chronograph and tachymeter bezel have become almost as closely associated with the Apollo programme as white spacesuits and the Saturn V rocket.

But the Speedmaster wasn't originally designed for astronauts.

When Omega introduced the model in 1957, it was conceived as a sporting chronograph. Its tachymeter scale — unusually moved onto the bezel — made it particularly suited to timing speed, and motor racing formed an important part of its early identity.

Spaceflight wasn't part of the brief.

And when NASA eventually needed a wristwatch for its astronauts, Omega wasn't simply handed the job.

The Speedmaster had to earn it.

What followed was an extraordinary sequence of heat, cold, vacuum, humidity, shock, acceleration and vibration.

Then, only a few years later, one would be strapped to the outside of a spacesuit on the surface of another world.

BEFORE THE MOONWATCH

The Speedmaster's journey into space actually began before NASA formally qualified it.

In October 1962, astronaut Wally Schirra wore his personally owned Omega Speedmaster CK 2998 aboard the Mercury-Atlas 8 mission, Sigma 7.

It hadn't been issued by NASA.

Schirra had bought the watch himself.

That made the CK 2998 the first Omega worn in space.

NASA, meanwhile, was preparing for something considerably more ambitious.

The Gemini programme would require astronauts to operate outside their spacecraft, while Apollo would attempt to put humans on the Moon.

Mission timing could be critical, and NASA wanted a wrist chronograph officially qualified as part of its astronauts' equipment.

A watch that worked perfectly well on Earth wasn't necessarily good enough.

NASA needed to know what would happen when it was subjected to conditions far beyond anything its manufacturer could reasonably have expected.

And so the testing began.

NASA TRIES TO BREAK A WATCH

NASA's requirements were uncompromising.

The chronograph needed to be manually wound, waterproof, shock-resistant, anti-magnetic and capable of continuing to function across enormous variations in temperature and acceleration. The Smithsonian records temperature requirements spanning 0°F to 200°F — approximately -18°C to 93°C — as well as acceleration of up to 12 G.

Omega's candidate was subjected to a punishing programme designed to simulate the extremes of spaceflight.

Heat.

Cold.

Humidity.

Vacuum.

Oxygen.

Shock.

Acceleration.

Decompression.

Vibration.

Noise.

These weren't tests intended to determine which watch kept the best time sitting on a desk.

NASA was effectively trying to discover which chronograph it could trust when conditions became hostile.

The Speedmaster wasn't untouched by the testing. But crucially, it continued to perform well enough to satisfy NASA's requirements.

On 1 March 1965, NASA formally declared the Omega Speedmaster:

“Flight Qualified for all Manned Space Missions.”

Omega's official historical record identifies that date as the beginning of the Speedmaster's formal relationship with NASA.

The watch had earned its place in space.

But laboratory testing was one thing.

The real test came three months later.

THEN IT WENT OUTSIDE

On 3 June 1965, astronaut Edward H. White II opened the hatch of Gemini IV.

He floated outside.

For approximately 20 minutes, White became the first American to conduct a spacewalk.

And strapped around the outside of his spacesuit was an Omega Speedmaster.

The photographs from Gemini IV became some of the defining images of early human spaceflight.

White appears suspended above Earth, attached to the spacecraft by a tether, manoeuvring through the vacuum of space.

The Speedmaster was no longer being subjected to simulated conditions inside a laboratory.

It was outside the spacecraft with him.

For collectors, the Speedmaster reference 105.003 consequently acquired one of the most recognisable nicknames in vintage Omega:

The “Ed White”.

But Gemini was ultimately preparation.

NASA's real objective was the Moon.

APOLLO 11

On 16 July 1969, Neil Armstrong, Buzz Aldrin and Michael Collins launched from Cape Kennedy aboard Apollo 11.

Four days later, Armstrong and Aldrin descended towards the lunar surface inside the Lunar Module Eagle, while Collins remained in lunar orbit aboard the Command Module Columbia.

All three astronauts had been issued Omega Speedmasters.

Then something happened that would determine which watch actually became the first worn on the Moon.

The Lunar Module's mission timer wasn't functioning correctly.

Armstrong and Aldrin therefore decided that one wristwatch should remain inside Eagle as a backup.

Armstrong later recalled the decision directly in NASA's Apollo Lunar Surface Journal.

So when Neil Armstrong climbed down the ladder and became the first human to walk on the Moon, his Speedmaster stayed behind.

Inside the Lunar Module.

Buzz Aldrin followed Armstrong onto the lunar surface shortly afterwards.

His Speedmaster came with him.

Strapped around the outside of Aldrin's spacesuit was an Omega Speedmaster Professional.

At that moment, the Speedmaster became:

THE FIRST WATCH WORN ON THE MOON.

A sporting chronograph designed in Switzerland little more than a decade earlier was now operating approximately 240,000 miles from Earth.

The Moonwatch had earned its name.

ARMSTRONG'S SPEEDMASTER SURVIVES

The decision to leave Armstrong's watch inside Eagle had an interesting consequence.

His Apollo 11 Speedmaster survived.

Today it belongs to the collection of the Smithsonian's National Air and Space Museum.

NASA transferred Armstrong's chronograph to the Smithsonian in 1973, where it remains preserved as an Apollo 11 artefact. The museum identifies the watch as a NASA-issued Omega Speedmaster with a stainless-steel case and Hesalite crystal.

Look closely and it doesn't resemble a carefully preserved collector's watch.

It looks used.

Because it was.

The Speedmasters issued to NASA astronauts weren't luxury accessories. They were pieces of equipment supplied to men undertaking extraordinarily dangerous missions.

Which makes what happened to Buzz Aldrin's watch even more remarkable.

THE FIRST WATCH ON THE MOON DISAPPEARS

After Apollo 11, Aldrin's Moon-worn Speedmaster was intended to join the growing collection of Apollo artefacts being preserved for posterity.

It was sent towards the Smithsonian.

It never arrived.

Somewhere between Aldrin and the museum, the watch disappeared.

Despite investigations and numerous claims over subsequent decades, the Speedmaster that actually accompanied Aldrin onto the lunar surface has never been conclusively recovered.

That leaves us with one of the greatest missing objects in watchmaking history.

Somewhere — assuming it still survives — is a Speedmaster that travelled from Earth to the Moon, descended aboard Eagle, spent time on the lunar surface and safely returned through Earth's atmosphere.

It survived one of the most ambitious journeys humanity had ever attempted.

Then disappeared during a comparatively ordinary journey on Earth.

There are few greater ironies in vintage-watch collecting.

COLLECTOR'S CORNER

NASA and the Smithsonian document the Speedmaster's selection following rigorous testing, its use during Apollo 11 and the surviving Armstrong and Collins chronographs held by the National Air and Space Museum.

WHY THIS WATCH MATTERS

The Speedmaster's story is sometimes reduced to:

Omega made a watch. NASA chose it. It went to the Moon.

The reality is far more interesting.

Omega didn't originally design the Speedmaster for space.

Wally Schirra bought one independently.

NASA subsequently needed a chronograph capable of operating in extraordinary conditions.

The Speedmaster survived the qualification process.

Then astronauts trusted it.

That distinction matters.

The Moonwatch story isn't compelling because a marketing department decided to associate a watch with space exploration.

The history came first.

The marketing opportunity came afterwards.

That authenticity is almost impossible to manufacture.

And it helps explain why a design originating in the 1950s can remain culturally relevant almost seventy years later.

A LESSON FOR VINTAGE WATCH COLLECTORS

The Speedmaster also demonstrates why reference numbers matter.

To someone new to vintage watches, numbers such as CK 2998, 105.003 and 105.012 can appear unnecessarily complicated.

But those references place individual watches within a historical timeline.

A CK 2998 connects us with Wally Schirra and the first Omega in space.

A 105.003 connects us with NASA qualification and Ed White's spacewalk.

A 105.012 connects us with Apollo 11 and the first watch worn on the lunar surface.

Tiny differences in cases, dials, bezels, movements and reference numbers can therefore represent completely different chapters in the history of a model.

For collectors, that's why research matters.

You're not simply establishing what a watch is.

You're establishing where it belongs in the story.

THE MWW TAKE

The Omega Speedmaster is a perfect example of why vintage watches can become much more than mechanical objects.

Remove the history and you're left with an excellent manually wound chronograph.

Put the history back in, and you're looking at a watch connected with some of the greatest technological achievements of the twentieth century.

The extraordinary part is how naturally that history developed.

A racing chronograph became an astronaut's personal watch.

That watch became NASA equipment.

NASA equipment became the first watch worn on another world.

And the actual watch that achieved that final milestone subsequently disappeared.

More than half a century later, Omega still produces a watch whose fundamental appearance is immediately recognisable alongside those worn during Apollo.

Few designs survive that long without becoming historical curiosities.

The Speedmaster hasn't.

Perhaps that's because the story attached to it remains so difficult to equal.

The Speedmaster started life measuring speed on Earth. Twelve years later, it was measuring time on the Moon.
