he Longines Spirit Flyback line symbolises the pioneering spirit that has always driven the brand. This chronograph watch with flyback function is testimony to Longines’ pioneering role in developing the technology. The winged-hourglass brand actually produced the first model equipped with a flyback function in 1925, then filed a patent that was registered on 16 June 1936: a world first. A revolutionary tool for conquering the skies, the flyback complication enables successive timing of different stages of a flight, thus facilitating navigation.

A veritable tool watch, the Longines Spirit Flyback is now adorned with Grade 5 titanium, an alloy that is both lighter and tougher than steel. Aesthetically, the chronograph is notable for its 42mm case with a satin-polished finish that plays on the contrasts between dark shades and subtle shine. A strong, sleek design coupled with cutting-edge technology gives this new timepiece an exceptional character.

The high precision of the Longines Spirit Flyback is ensured by the exclusive Longines L791.4 calibre, which is resistant to magnetic fields and equipped with a silicon balance-spring. Endowed with a power reserve of up to 68 hours, this movement is chronometer certified by COSC (Contrôle officiel suisse des chronomètres). A transparent case back reveals every tiny detail of the calibre and its oscillating weight, which is engraved with a globe, the emblem of the Longines Spirit collection.

This new version features a bidirectional rotating bezel enhanced by a black ceramic insert with luminescent markers. Topped by an anti-reflective sapphire crystal, the anthracite dial is flanked by a small seconds sub-dial at 9 o’clock and a 30-minute counter at 3 o’clock. The gilt hands and numerals, coated with Super-LumiNova, ensure optimum legibility in all circumstances, whether in the air or on the ground.

Water-resistant up to 10 bar (100 metres), the watch comes with an interchangeable titanium bracelet or black and grey NATO strap developed especially for this model.
