Wyler Geneve Tourbillon - a Wonder of Shock-Protection

When the timepiece is fully wound, the balance wheel amplitude is slightly higher than the optimum level, then it stabilizes and drops as the power reserve approaches the zero point. If the watch's wearer keeps the trust index hand in the middle part of the scale when he winds the watch, this way it provides optimum accuracy and does not over-wind the timepiece.At 12 o'clock there is the 24-hour GMT sub-dial with a single hour hand.This way the watch's creators provided the crown with failsafe protection.The third level of protection lies at the heart of the watch's movement. There is an aperture on the dial positioned at six o'clock that offers the view to the flying tourbillon. To provide maximum shock-absorption, it is fixed to aluminum bridges on two shock-absorbing springs. Thus, the tourbillon itself is suspended within the suspended movement while rotating on its own axis. It performs one revolution every 60 seconds, compensating for the gravity effects on the mechanism.Above the tourbillon cage aperture at 6 o'clock you will notice two important meters used as the reflection of the timepiece's accuracy. At 9 o'clock there is the 120-hour power reserve indicator showing the movement's charge. On the opposite part of the dial at 3 o'clock there is a trust index indicating the balance wheel amplitude.
