Omega SpeedmasterThe Speedmasters history goes back to 1957 when it was introduced as a sports and racing chronograph. However it got picked up by NASA and soon would be known as the ‘first watch worn on the moon’. NASA devised the most demanding tests of a watch’s resistance with the aim of equipping astronauts with the most durable timepieces. The NASA selection tests were conducted from 1964 until 1965 and featured a: high temperature test, low temperature test, vacuum test, humidity test, corrosion test, shock-resistance test, acceleration test, low pressure test, high pressure tests, vibration test and sound testOmega passed all the tests and was officially certified by NASA and the whole crew of the Apollo 11 astronauts each wore a Speedmaster. However, a common misconception is that Armstrong was the first to set a foot on the moon with the Speedmaster where in fact it was actually Buzz Aldrin. Neil Armstrong decided to leave his one as a backup aboard the spacecraft.Ever since, the Speedmaster Professional is one of the most well-known watches of Omega. Omega sticks with its winning formula as the contemporary look makes it difficult to distinguish between modern and vintage pieces, it's left to some subtle differences. Now that is truly timeless.
