NASA’s Apollo program likely represents the most ambitious, audacious, and downright impressive adventure of all time, and for those of us in the watch enthusiast community, you can’t read “Apollo” without thinking of the Omega Speedmaster. Becoming the NASA flight-certified watch for the Apollo program has made an icon of what started out in 1957 as Omega’s motorsports chronograph, and there’s no other watch that carries the nickname “The Moonwatch.” With Apollo 11 celebrating its 50th anniversary and vintage Speedmasters becoming more and more valuable to collectors, Sotheby’s has announced an upcoming Speedmaster-themed sale on July 19th in New York City.
