The architecture of this movement has enabled a coherent and rational arrangement of components. It avoids superfluous superimpositions and features technical solutions that optimize its functions. For example, the geometry of the column wheel has been designed to ensure perfect synchronization of the control of the different levers, even over the long term. This synchronization is essential for creating a faultless timing instrument. This new design has been implemented to conserve regulation and ensure perfect long-term operation.
Operation: the user can start or stop the chronograph by means of a pusher located at 10 o'clock. The flyback function can be reset to zero at any time using the pusher located at 8 o'clock. To stop: use the start/stop pusher located at 10 o'clock to stop the chronograph, then press the RESET/FLYBACK pusher
The hand of the chronograph minutes counter can be used in countdown mode by means of a pusher located at 9 o'clock. Pressing it once activates the function. An aperture at 7 o'clock displays the mode selected: ON for countdown mode and OFF for chronograph mode.
Operation: a pusher at 4 o'clock enables the hand to be adjusted quickly between 59 minutes and 01 minutes. Pressing lightly will advance the hand by one minute, while pressing more firmly will advance it by 5 minutes. Once the countdown time has been set, the pusher at 10 o'clock can be used to start the chronograph. When the minutes hand reaches zero, the display at 7 o'clock changes to OFF. At any moment, the function can be reset to zero via the flyback by pressing the pusher at 8 o'clock.
BALANCE WHEEL WITH VARIABLE INERTIA
This type of balance wheel which represents the ultimate in innovation, guarantees greater reliability when subjected to shock and also during assembly and dismantling of the movement, thus achieving better chronometric results over time. The index is eliminated, thereby allowing a more precise and repeatable adjustment using 4 setting screws.
FAST ROTATING BARREL (5 hours per revolution instead of 7.5 hours)
This type of barrel provides the following advantages: - The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby
increasing performance. - Provision of an excellent mainspring delta curve with an ideal power reserve/performance and
WINDING BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE
The wheel with a central developing profile and a pressure angle of 20° promotes rolling movement more effectively, compensates differences between centers, ensures excellent torque transmission and a distinct improvement in performance.
