This could very well be the most important wristwatch of the 20th century, lost. Neil Armstrong wore his Omega Speedmaster to the moon, but not on it. His module’s mission timer failed, so he left it on board. Buzz Aldrin, however, wore his Speedy on the lunar surface and thereby his watch became the stuff of legends. But did you know that upon return, Aldrin’s watch was lost or stolen on its way to the Smithsonian? It was. Armstrong’s Omega made it, but Armstrong’s Omega wasn’t the first watch on the moon. There have been a handful of folks claiming to have possession of Aldrin’s Omega, but none appear to have been credible. It is likely that the person who took the Aldrin Omega had no idea of its significance, but at this point, it’s fair to say this is one of the great horological mysteries of the modern era – where is Buzz Aldrin’s Omega Speedmaster?
