All the watches worn on the Moon were part of the Speedmaster collection and were equipped with the legendary calibre 321.
During the Apollo 11, 12, 14, 15, 16 and 17 lunar missions, the astronauts wore Speedmaster model references ST 105.012 and ST 145.012.
Captain Eugene "Gene" Cernan also wore a Speedmaster ST 105.003 during the Apollo 17 mission.
The Speedmaster is still part of our current collection and has since become an icon in the watchmaking world.
