MECHANICAL RESISTANCE
Finally, more than 100 checks are carried out through the manufacturing process of each watch, in addition to random checks during production. To simulate the daily handling that watches undergo over 10 years, thousands of manipulations are carried out: the clasp is opened and closed, the crown is pulled out, turned and pushed back in, the watch is removed and put back on the wrist, the push-pieces are pressed, etc.
Other tests are also carried out, reproducing more violent shocks that are perhaps rarer in the watch's life.
