Christina Koch — watch collection

About Christina Koch’s watch collection

Christina Koch is a NASA astronaut and engineer who has logged more than 680 hours in space across multiple missions to the International Space Station. She served as flight engineer on Expedition 59/60 and commanded the SpaceX Crew-5 mission. Koch holds the record for the longest single spaceflight by a woman, spending 328 consecutive days in orbit during her 2019-2020 mission. Her background in electrical engineering and her extensive experience in space exploration have established her as one of the agency's most accomplished mission specialists.

The Christina Koch watch collection centres on Breitling's Navitimer Cosmonaute line, a series specifically designed for space exploration. She has been spotted wearing the Breitling Navitimer Cosmonaute Ref. A18061, a chronograph built around the Venus calibre 178 hand-wound movement. This model features the distinctive 24-hour dial that proved essential during early space missions, and Koch wore it during her reception of the Congressional Space Medal of Honor in formal dress uniform.

Koch's collection also includes the Breitling Navitimer Cosmonaute Artemis II Ref. A27364, another chronograph with the characteristic 24-hour dial. Both timepieces in the Christina Koch watch collection reflect the practical requirements of spaceflight: reliable timekeeping, legible instrumentation, and a proven track record in aerospace applications. The Navitimer Cosmonaute line carries historical significance dating to the earliest phases of human spaceflight, connecting modern missions to the pioneering work of earlier space programs.
