A perpetual calendar and a precision moon phase
Technically prestigious, the Tonda Centum has a perpetual calendar and a precision moon phase, two Haute Horlogerie complications which are only very rarely associated due to their respective complexity.
Retrograde perpetual calendar movement
The PF333 movement, produced entirely in-house at the Parmigiani Fleurier manufacture, has the QP mechanism on the main plate, to which a module is added for the precision moon phase. This automatic movement has a 55-hour power reserve, thanks to its two series-mounted barrels. This device stabilises the distribution of energy in the movement and increases the reliability of its rate.
