This particular Speedmaster is manufactured in 1966 and sold to the Swiss market. It’s the archetypal Speedmaster Professional vintage chronograph: lyre lugs, stepped dial, applied Omega logo. It belongs to the generation housing the mythical caliber 321, a Lemania caliber, column-wheel, lateral-clutch movement with Breguet overcoil – a true chronometer grade wristwatch movement of the old school.

The Speedmaster was originally introduced in 1957 as a racing watch, and it wasn't until 1969 – when the hand-wound chronograph accompanied the crew of Apollo 11 onto the surface of the Moon – that it received the legendary status that it holds today. The two references of our Speedmaster were worn by the crew of Apollo 11, Neil Armstrong wore a 105.012, Michael Collins wore the later 145.012, and Aldrin's watch – the timepiece that actually went on the Moon – is currently missing as it was presumably stolen on the way to the Smithsonian in 1970. Speedmasters are still being worn to this day on the International Space Station.
