The Navitimer is a unique watch designed for space missions. It was worn by astronaut Scott Carpenter during the first orbital flight of the Aurora 7 capsule on May 24th, 1962. What makes this version special is its ability to display all 24 hours in a single circular sweep, making it easy to tell day from night in the vastness of space. The Cosmonaute also features a Flyback mechanism, allowing for continuous timing without the need to stop and restart the chronograph. Its reference number is A2232212/B600.
