The next generation of that pioneering aviation spirit

The Longines Spirit collection has been expanded with a piece equipped with a flyback function. A new exclusive Longines calibre, resistant to magnetism and equipped with a silicon balance spring, drives this timepiece. Extremely precise, and with a power reserve of 68 hours, this movement is certified as a chronometer by COSC. A transparent case back reveals all the details of the calibre, including a personalised weight engraved with the globe representing the Longines Spirit collection and the name Longines Flyback. This new model is also distinguished by its refined aesthetics and particularly meticulous finishes, which range between satin, matt, polished and engraved details. It features a bi-directional bezel enhanced by a black ceramic insert with luminescent markers and a black sunray dial. The 42mm steel case is fitted with a beige NATO strap.
