When Neil Armstrong became the first human to step on the Moon on July 21, 1969 at 2.56 GMT, the world rejoiced. Buzz Aldrin was 15 minutes behind him and the Speedmaster Professional became the first watch to be worn on the Moon. Story goes that the tests that NASA performed on the chronographs that were submitted to the agency in 1964 were designed to destroy the watches. In the end, only one watch survived: the Speedmaster.
