Zenith’s new Stratos Striking 10th also has a Flyback function. The flight route is determined by the intended destination and time. Before the Flyback function was invented, the wearer had to press two different buttons three times each time to perform the stop reset reset timer operation. However, this is undoubtedly too complicated and slow for pilots when controlling the aircraft. Therefore, the handy watchmaker developed the Flyback function, which only needs to press a key once each time to stop, reset and restart the timing operation. This allows pilots to calculate new routes immediately, which is an advantage for them, especially when they land based on the time communicated by the console.
