Astronaut Lt. Commander Scott Carpenter used to wear a Breitling Navitimer during the Korean war. As he was about to participate in a space mission, suggested that a 24-hour watch would make sense in space. He contacted Breitling to produce such a watch.

For mission “Mercury-Atlas 7” in 1962, NASA performed tests in order to choose which timekeeper the astronaut would be using inside the capsule; the winner of which was the Breitling Navitimer. (At this stage, I doubt this could be the 24h version.)
In May 24th 1962, Scott Carpenter performed the second U.S. manned orbital space flight while wearing his 24-hour Navitimer, onboard Aurora 7 sitting atop the MA-7 rocket. That certainly made this Breitling the first Swiss watch worn in space.
This watch was damaged by water during recovery (because of the slide rule, the first Navitimers were not water resistant), and replaced by Breitling. The first 24h Navitimer was never seen again.
Soon the watch became commercially available under the name “Navitimer Cosmonaute”. Breitling never stopped producing Cosmonautes since then. The current production Cosmonaute shows many similarities with the original model.
