The Only Privately-Owned Astronaut Watch Worn on the Moon Is Up for Auction

Forty-four years ago, David Scott's watch broke while he was out for a walk.

Somehow, the crystal that protected the wristwatch's face popped off. Scott did not notice it had broken until after he had come back inside. Fortunately for him, he had another watch to wear.

Of course, none of that would be noteworthy had Scott not been on the moon at the time.

He was also the first and only astronaut in history to wear a personal watch on the surface of the moon — a watch that is now heading to auction.

On Oct. 22, after a week of online bidding that will open at $50,000, Scott's personal Apollo 15-used chronograph will be sold by RR Auction of Boston. The sale is expected to draw watch and space collectors alike, as it the only time a watch worn on the moon has ever been offered.

Omega versus Bulova

When David Scott launched from Earth, when he landed on the moon and when he and Apollo 15 astronaut Jim Irwin went outside for their first two moonwalks, Scott wore a NASA-issued Omega Speedmaster chronograph.

Selected by the space agency after a series of extensive tests, the Swiss-made watch was worn by all of the Apollo astronauts, from Neil Armstrong to the last man to walk on the moon, Gene Cernan. Omega inscribed the back of the Speedmasters it sold with the proud claim, "first and only watch worn on the moon."

Only the "only" wasn't precisely true.

Unbeknownst to most at NASA, let alone on Earth, at the time, Scott agreed to carry a Bulova-made wristwatch and stopwatch on board Apollo 15 after a bid by the New York-based watchmaker to demonstrate that an American-made piece could function as well, if not better, than the Swiss Speedmaster.

For Scott, it was all about ensuring that the mission was a success. For example, a situation could arise during their moonwalks that would require a precise knowledge of the oxygen and water remaining in the spacesuits' life support backpacks.

"Under certain anticipated operational conditions, the only method of monitoring these vital systems was with a wrist chronograph," Scott stated in an interview. "I only had the NASA-provided Omega Speedmaster, which was a single point failure under these conditions."

"As a matter of prudence, I then decided that I would also carry the Bulova as a backup," Scott recalled.

That decision ultimately paid off, as Scott discovered the crystal had gone missing from his Speedmaster following his second moonwalk. On Aug. 2, 1971, as he embarked on his third and final excursion out onto the lunar surface, Scott used the Velcro watch strap he wore on his first two moonwalks to don his Bulova-made backup.

Unknown, unauthorized and misidentified

Though you would not know it unless you were looking for it, the Bulova chronograph can be seen in the footage and photos taken of Scott as he saluted the U.S. flag, worked near the lunar rover and famously proved for all those on Earth that Galileo was right — a feather and a hammer fall at the same rate in the absence of an atmosphere.

He continued to wear the Bulova once he was back inside the lunar lander, all the way through to his splashdown on Earth with Irwin and Apollo 15 command module pilot Al Worden. A photo of the three astronauts floating in a life raft after the mission was completed provides perhaps the clearest view of the Bulova strapped to Scott's wrist.

Not that anyone noticed at the time.

"After the mission, only my supervisor and my crew knew that the Bulova [watches] had been carried," Scott stated. "Bulova was not informed."

And that may have been it had a question not arose about some souvenir envelopes ("covers") Scott had also flown for a German stamp dealer. An investigation, called for by Congress, revealed the "unauthorized timepieces."

"Thinking [the chronographs] might be useful, particularly for the possible emergency timing of a manually controlled propulsion maneuver, Scott carried them on the mission but without prior authorization," NASA officials reported in a 1972 press release.

The space agency withheld the name of the manufacturer to avoid commercialization.

The secret out, the make of the watches would still remain unknown for 25 years, and even then, the wrong company was identified.

"In 1996, 25 years after the mission, I was queried about a backup watch. At that time, I slightly recalled that it was a Waltham. However, in 2014, after further researching the issue for an article on watches, I concluded that frankly, back in 1996, I just made a mistake – it was a Bulova, not a Waltham," Scott explained.

"Knowing what watch I wore was not a priority during [the] mission discussions, especially in light of the complexity of our flight to the moon. I hadn't fully researched many of the ancillary parts of the mission," he added. "More things [came] into focus in 2014 as more people were beginning to research Apollo in more depth."
