LONGINES SPIRIT FLYBACK
Round steel case, 42.00 mm, with transparent sapphire crystal case back.
The LONGINES Spirit Flyback testifies to LONGINES's pioneering role in the development of this technology. The winged hourglass brand produced the first model with a flyback function in 1925, later filing a patent that was registered on 16 June 1936: a world first. A revolutionary instrument for conquering the skies, the flyback complication made it possible to successively time the different phases of a flight, thus facilitating navigation.
