Buzz Aldrin wore arguably the most important watch in history.
He had an Omega Speedmaster Professional strapped to his wrist when he followed Neil Armstrong out of their lunar lander and onto the surface of the moon during the Apollo 11 mission on July 20, 1969. Armstrong had left his Speedy in the lunar module as backup for a malfunctioning digital timer, making Aldrin’s watch the first to ever be worn on the moon.
Since 1973, Armstrong’s watch has resided at the National Air and Space Museum, but Aldrin’s watch disappeared while in transit from NASA to the same museum in 1971. It has never been recovered, making it the world’s greatest (and likely most valuable) lost timepiece.

As a piece of government property, Aldrin never owned his famous Moonwatch. But as a collector and longtime Omega ambassador, the now-96-year-old astronaut legend has amassed an impressive watch collection over the years.
Several watches from Aldrin’s personal collection are going up for auction at Sotheby’s this week, and while there are plenty of Omegas to choose from (eight, to be exact), the coolest watch in the lot actually comes from a different brand.
