CONFIGURED FOR SPACE TRAVEL
Since its first journey into space in 1962, the Navitimer Cosmonaute has remained a trusted companion for astronauts. From early orbital missions to extended stays aboard Mir and the International Space Station, it has followed those operating beyond Earth’s atmosphere.
Astronauts have continued to choose the Cosmonaute for both professional missions and personal wear. NASA astronaut Scott Carpenter wore it during his Mercury-Atlas 7 mission, while later figures like Claudie André-Deshays brought it aboard Soyuz missions. More recently, it has accompanied astronauts on missions to the International Space Station, underscoring its lasting relevance. Its 24-hour display, designed to distinguish day from night in orbit, remains a defining feature.
The Navitimer B02 Chronograph 41 Cosmonaute stands as both tribute and continuation. A watch conceived for space, and still trusted by those who go there.
