Energy under control
When a watch hits the floor from the height on one metre it experiences a deceleration of 5,000G — in other words the balance is subjected to a force 5,000 times its own weight. The reaction threshold of the Incabloc® shock absorber is around 35 grams.
The system acts in two stages:
- The energy of the shock, transmitted by the most resistant part of the balance-staff (the pivot shank) is entirely absorbed by the bearing block (buffer);
- The system recenters instantly and exactly (action of the lyre-spring®).
