Half the path and go back!
Retrogade hands, does it mean anything to you? This horological complication uses a non-circular display system. The hands run along an arc of a circle and then come back to their starting point once they reached their goal. According to this principle, the seconds and minutes are displayed on KLOK-02. While the seconds retrogade hand keeps going in its mad rush, the minutes hand takes its time, going forward every 5 minutes. What if we also slowed down the movement?
