LONGINES Spirit COSC Automatic Brown Leather Strap L38214532

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.
