PreciDrive can achieve a precision which can pass the COSC chronometer certification, provided the watch is not exposed to impacts, and kept at a temperature of between 20°c and 30°c. This precision can be achieved thanks to the thermo-compensation operating principle, which controls and regulates the motor pulses according to changes in the ambient temperature. By virtue of combining the quartz and integrated circuit in the same waterproof case, the precision is insensitive to moisture.
Thanks to a new integrated circuit, HeavyDrive technology provides an anti-shock system and expands the options for hand unbalance. The weight of an innovative hand design or material is no longer an obstacle, as HeavyDrive is able to support unbalances of over 200% for a traditional second hand and 20% for a traditional minute hand. The movement’s new on-board electronics detect and then manage the shock, whilst the motor generates a counter pulse to lock the hand in its position during the shock. This intelligent shock management prompts the motor to react in a fraction of a second if a certain shock threshold is exceeded. The energy used to counter this force remains minimal, and the movement’s autonomy is thus preserved.
PowerDrive controls the running of the chronograph motors, and can increase the hand movement speed to more than 200 Hz (i.e. 200 hand jumps per second in either direction of rotation). This technology improves the hand movement control, making for a highly dynamic display.
PowerDrive also provides numerous counter programming options. This technology gives the customer multiple display combinations.
Thanks to a latest-generation micro-controller capable of controlling several motors, the hand movement speed can be as much as 200 jumps per second in either direction of rotation.
The increased hand rotation speed has no effect on the movement consumption; it is even considerably reduced in high-speed mode.
This new micro-controller has a built-in flash memory, enabling multiple display combinations on the various counters. This display flexibility, combined with rapid two-way movement of the hands, provides in particular numerous retrograde display options and instantaneous resets.
Vacuum sealed in a ceramic case, the integrated circuit (IC) and quartz are protected from any influence of moisture. The IC has a built-in oscillating system for measuring the quartz temperature. This measurement can correct the rate, by compensating for the frequency deviation as a function of the temperature. This results in very high precision, in line with the performance requirements demanded by the quartz chronometer qualification test (COSC).
