Longines Longines Spirit Flyback

The calibre L791.4 is an automatic movement featured in the Longines Spirit Flyback watches. It is crafted exclusively by ETA for Longines with the standout flyback chronograph complication based on a column wheel mechanism. Operating at a beat rate of 28,000 vibrations per hour, L791.4 provides a robust 68-hour power reserve, ensuring reliable performance of all the functions — hours, minutes, seconds, and chronograph. It further enhances its performance with a silicon balance spring. A COSC-certified chronometer, this movement also showcases a stunning array of finishes. The blued screws and prominent blued column wheel create an eye-catching contrast, while the plates and bridges feature fine perlage decoration.
