LONGINES SPIRIT FLYBACK L3.821.4.93.2 – Ø 42.00 mm
Pioneering flyback chronographs
The Longines Spirit Flyback bears witness to Longines’ pioneering role in the development of this technology. The winged hourglass brand produced the first model equipped with a flyback function in 1925, then filed a patent which was registered on 16 June 1936: a world first. A revolutionary tool for conquering the skies, the flyback complication enabled successive timing of different stages of a flight, thus facilitating navigation.
