The newly developed Calibre Heuer 02 COSC Flyback manufacture movement now allows TAG Heuer to flirt with its past. A rarely seen function in chronographs due to its difficulty to implement, the flyback function makes it possible to reset the chronograph hand and commence a new timing without the need to stop it first, saving valuable time in high-pressure situations, such as recording lap times at the racetrack.
