After the Omega Speedmaster Professional won the race to the Moon in 1969, Omega thought it was time to come up with a watch that was perhaps a bit more up-to-date and ready for the 1970s — design-wise, that is, as the watch would still need to handle the same abuse as the Speedmaster Professional “Moonwatch” could. Sometime in 1969, Omega introduced the first Speedmaster Mark II, which was actually a Speedmaster Professional Mark II.

The Speedmaster Mark II came with the same Lemania-based movement as the Moonwatch, Reference 145.022. This movement is Omega’s Caliber 861 and was in production from 1968 through about 1996, when it was succeeded by the Caliber 1861 movement. The Speedmaster Mark II had a barrel-shaped case that looked totally different from the asymmetrical Speedmaster Professional case. The regular Speedmaster, which was issued to NASA astronauts is still in production and emblematic Omega collector watch.
