The original Speedmaster 'Broad Arrow' was created in 1957 and was so named because of its distinctive hands. It is not only one of the most iconic chronographs, it was the first chronograph wristwatch with its tachymeter scale engraved on the bezel — a feature designed for the benefit of racing drivers.
However, when it comes to speed, I’m sure there’s nothing quite as exhilarating as jetting off to the moon. Two years later, a second version was released with a black aluminium bezel, lollipop seconds hands for Air Force orders and 'Alpha' style hour and minute hands for better legibility. It was also the first to be worn in space on the wrist of Walter Schirra on October 3, 1962. Like its predecessor, it featured the highly collectable Calibre 321 movement.
In 1963, the third generation was the first watch to pass NASA’s strict testing and was worn on Gemini and Apollo missions. This watch was strapped to astronaut Ed White when he made his spacewalk on June 3, 1965, and featuring its simplified calibre 861 was worn by Neil Armstrong and Buzz Aldrin when they took their giant leaps on the lunar surface in 1969.
In 1964, the distinctive twisted lugs where introduced, which allowed for an asymmetric case that in turn protects the crown and pushers.
