The Breitling and Scott Carpenter
From Chronopedia
The 24-hour version of the Navitimer was developed at the request of NASA Astronaut Scott Carpenter, who wore a modified Navitimer with a 24 hour movement and dial on his Mercury flight in 1962. Carpenter later returned his watch to Breitling for servicing, after having been submerged in seawater during space capsule recovery. Breitling replaced the watch with a new "Cosmonaute" model. The whereabouts of the original which flew into space is unknown.
