The Audemars Piguet Quantième Perpétuel Jules Audemars Replica Watch of the 30 or 31-day months is controlled by a cam – which is itself connected to a wheel – on which the various lengths of the month are defined. The protruding sections of around its circumference represent 31-day months, and the notches those of 30 days. On the same axis, a new wheel bearing a cam indicating standard months of February and a leap-year month of February performs one turn every four years and is thus able to keep accurate track of the leap-year cycle.How can a timepiece, merely by the meshing of its toothed wheels, levers and clicks, successfully indicate the day, the date, the month, the moon phases and the leap-year cycle? The perpetual calendar system is an admirable mechanical reproduction of our calendar.
The skill and mastery acquired by Audemars Piguet Jules Audemars Replica Watch watchmakers in the field of ultra-thin movements have enabled them to house the 355 parts of the Perpetual Calendar within a tiny space just 4 mm thick.The perpetual calendar mechanism is thus allied with an excellent base movement. The larger the barrel diameter, the greater the power reserve – which in this case amounts to 40 hours. The variable- inertia balance serves to ensure particularly fine adjustment and guarantees peerless accuracy. Moreover, the larger balance diameter also enhances the precision of the watch.This same concern for performance led Audemars Piguet to choose a central rotor rather than an integrated mini-rotor. The impeccable mirror-polished finish of the gear train and the use of 38 top-quality jewels enables optimal transmission of the force from the barrel to the escapement. This particular technical solution means that the oscillating weight runs on another level than the barrel and the balance, thereby providing the latter two organs with more space in which to operate.
The finishing and decoration of this movement are entirely on a par with this wealth of technical ingenuity. They will also be pleased to know that even the parts hidden from their Audemars Piguet Replica Watch are the object of meticulous care. The mainplate features five different circular-graining diameters that create an exquisitely refined effect, while even the inside of the case-back is also circular-grained. By way of example, not only is the upper part of the bridges adorned with a Côtes de Genève motif, but the invisible lower part is also finely circular-grained. All the bridges are chamfered and polished by hand. Connoisseurs will take particular delight in the work on the internal and exterior angles.
