Longines watch Spirit Pilot Flyback 39.5mm blue manual winding steel L3.721.4.93.6

The LONGINES Spirit Pilot Flyback collection captures the brand's constant commitment to innovation. With its flyback function, this chronograph highlights LONGINES' pioneering experience in this field. In the early 1930s, the winged hourglass brand launched its first model with a flyback function and obtained the patent for the technology on June 16, 1936, marking a first worldwide achievement. Designed as a revolutionary tool for pilots, the flyback complication allows different phases of flight to be timed in succession, significantly improving navigation efficiency. The precision of the LONGINES Spirit Pilot Flyback is brought to life by an exclusive Longines caliber, equipped with a silicon balance-spring and resistant to magnetic fields. This hand-wound mechanical model is officially certified as a chronometer by the COSC.
