http://www.thewatchbox.com This is the Moon Watch. It's called that because it was the first watch to be worn on the Moon. And like NASA's plastic rendition of Old Glory, historic "firsts" are flags that fly forever. During the late 1960s, the Omega Speedmaster Professional was tested and selected over a stacked field of first-class opponents to become the official flight and space walk-certified timepiece of NASA's current and future space programs. On July 20, 1969, Neil Armstrong wore one as he left the Apollo 11 capsule and took his famous step/leap. The Omega Speedmaster Professional has changed little since that time, and it remains in service with NASA virtually unchanged from the reference that flew with Neil and Buzz. This reference 145.022 Speedmaster Professional is representative of the Omega caliber 861 Speedy Pro that flew with the late Apollo missions and inaugurated the era of the Space Shuttle in 1978. This Omega Speedmaster Professional embodies all of the features that make the watch an icon of its brand and a piece of Americana. The famous acrylic crystal is present and correct; NASA wanted to avoid shatter-prone mineral and sapphire units for flight duty. Inside, the Lemania 1873-based Cal. 861 is tank-tough and ready for the final countdown. Naturally, it is a manual wind watch, because NASA was said to have reservations about the viability of rotor-wound automatic systems in zero-gravity. This Omega Speedmaster Professional 145.022 ST71 is available from thewatchbox.com in excellent condition. The original tritum-lumed dial and baton hands are present and correct; the series 1039 bracelet presents in outstanding condition and interfaces with 516 end links. Video and content by Tim Mosso.
