The LONGINES Spirit Pilot Flyback collection captures the brand’s persistent drive for innovation. This chronograph, with its flyback function, highlights LONGINES’ pioneering expertise in this field. The winged hourglass brand introduced its first flyback-equipped model in the early 1930s and secured a patent for the technology on June 16, 1936, marking a world-first achievement. Designed as a groundbreaking tool for pilots, the flyback complication makes it possible to time successive flight stages, greatly enhancing navigational efficiency. The precision of the LONGINES Spirit Pilot Flyback is powered by an exclusive Longines calibre, fitted with a silicon balance spring and resistant to magnetic fields. This hand-wound mechanical movement is officially certified as a chronometer by the COSC.
