The Longines Spirit collection has been expanded with a model featuring a Flyback function. A new exclusive Longines calibre, resistant to magnetic fields and equipped with a silicon balance spring, powers the timepiece. Extremely precise and with a 68-hour power reserve, this movement is certified as a chronometer by the COSC. The transparent caseback reveals all the details of the calibre, including a personalised weight engraved with the globe that is the symbol of the Longines Spirit collection and the name Longines Flyback. This new model also stands out for its refined aesthetics and finishes with ultra-high precision, with satin, matte, polished and engraved details. It features a bidirectional bezel decorated with a blue ceramic insert with luminescent indexes and a blue dial with a sunray finish. The 42 mm steel case is paired with a bracelet in interchangeable stainless steel.
