When it comes to watches worn in space, everyone knows about the Omega Speedmaster and the iconic moment in history where it became the first watch worn on the Moon. But only the clued up few of you may know that the first Swiss wristwatch worn in space was the Breitling Navitimer Cosmonaute.
Scott Carpenter is the reason why the Breitling Cosmonaute exists. He was one of the original astronauts selected to be part of NASA’s Project Mercury back in 1959. After wearing a standard Navitimer during his time as an air force pilot, he approached Breitling and requested them to produce a Navitimer with a 24-hour dial. Breitling registered the name "Cosmonaute" in 1961 and then in 1962 a modified Navitimer with a 24-hour dial was the first Breitling to go to space.
The Cosmonaute was powered by the Venus 178 movement, a very reliable column wheel chronograph movement. The main difference between the Navitimer and Cosmonaute is the use of the 24-hour dial which was required as the hour hand only moves across the whole dial once per day.
