This 2015 edition of the audemars piguet royal oak perpetual calendar replica watch has a 2mm wider case, which measures 41mm, excluding the crown. And is available in four different versions: two in stainless steel and two in rose gold; with two “Grande Tapisserie” guilloche dial options: navy blue or silver. The complications are spread out, with the months and leap year exhibited at the 12 o’clock position; date at the 3 o’clock position; day of the week at the 9 o’clock position; and the moon-phase featured at the 6 o’clock position.
A perpetual calendar watch is a complex micro-mechanical device engineered to automatically adjust to the varying number of days in each month and even accounts for leap years. Actually this new audemars piguet royal oak replica requires a correction every 125 years and 317 days for its moon-phase astronomical indicator, but still that’s quite impressive. This watch will almost definitely not need any adjustments for the original owner’s lifetime, unless we have a tremendous break-through in the medical field to stretch out our current life-span. Leaving this timepiece for a second generation to cherish and “adjust” to time. Another new feature is the 52-week indication being displayed by a central hand pointing out the scale in the flange ring.
The Audemars Piguet Replica Watches is powered by a self-winding caliber 5134, with 38 jewels and up to 40 hours of power reserve. The movement operates with 374 moving parts and uses a mobile stud-holder, all these complications are balanced with variable inertia blocks. The oscillating weight is guided by a peripheral ring rolling on four ruby runners, which reduces friction and wear to a minimum. This updated movement is completely visible through the glare-proofed sapphire crystal caseback.
