The watch, in its final form, undergoes a last test on the Fleuritest simulator.
A 24-hour operating test is conducted on the robotics simulator, which recreates the movements of a nycthemeral cycle, alternating between active or extremely active phases and calmer ones. Variations in rate are analysed by means of an artificial vision system using digital cameras.
Fully computer controlled and synchronized by GPS, the machine observes the time as will the future wearer but with greater acuity.
The precision of the watch must fall within the range of 0 to +5 seconds per day.
At the end of the test, if the watch has passed, a certificate is issued for each watch, specifying the individual number on the movement and the case.
The watch is then entitled to the certification "FQF, La Haute Horlogerie certifiée".
