1972 Omega Speedmaster 145.022 CALIBRE 861 Rare Straight Writing "Moon Watch" Case Back

The Omega Speedmaster Professional is by far one of our most favorite chronographs. The Speedmaster has an incredible history starting with automotive racing moving into flight and eventually to NASA and the U.S. Space Program.  There are many subtle differences within the vintage Omega Speedmaster range of references that make them all slightly unique and different. This specific example is no exception as you will find that this 1974 Omega Speedmaster professional possesses the rare commemorative straight writing "moon watch" case back (145.022-69 inside) which was produced from 1970 to 1973. Based on the serial number this watch was produced in 1972 and is in fantastic condition.The straight writing case backs were Omega’s first commercial response to the Speedmaster’s involvement during the NASA 1969 Moon landings. There are actually three different variants of the straight writing case backs and these are quite rare due to the fact that they were only produced from 1970-1973 and were placed on a small number of actual production watches.
