The classic status of Audemars Piguet’s Royal Oak series is without a doubt, its case is polished, and the unique shape has always been to the top of fashion trend. However, the Royal Oak series has a more classic function, I think you really need to learn it.
When it comes to the distinction between the Royal Oak series and the Royal Oak Offshore series, there is a very important point. In addition to the different details of the case design, the Offshore series prefers a more sporty design, while the Royal Oak series goes a more classic performance, so the design and fluency of the case are more refined and stronger than the Offshore series, even if the Royal Oak series has added complex functions, it still has to maintain a extra-thin thickness, making the overall watch not too large and more suitable for formal wear and multiple occasions.
The Royal Oak Series Is Perfect for Formal Wear and a Variety of Occasions
One of the most classic features of the Royal Oak Collection is the Perpetual Calendar, which is housed in the same classic Royal Oak case and paired with the rare green dial, making it a special highlight among the Audemars Piguet Royal Oak Perpetual Calendar watches.

The perpetual calendar display is the function of all mechanical movements that best describes astronomy and time. The perpetual calendar is a romantic and sensible mechanical function for me: human observe astronomical phenomena, and begin to record the changes in nature and time, further dividing the time we use into hours, minutes and seconds, and then with the month, week, date, and later we find the strange orbital irregularity of the star, and then know the method of the leap year calculation.
The perpetual calendar divides the celestial movement into a complex gear after the actuarial calculation, and then displays it on the watch by hours.
This reflects the relationship between human beings and nature. In the mechanical movement, a series of mathematical and mechanical engineering procedures must be used to show the time law of human planning with the interlocking relationship between gear multiples and gear shapes, then perpetual calendar, the moon phase display and etc. were born.

Classic Symbol One: Practical Perpetual Calendar
Audemars Piguet first put the leap year display into the perpetual calendar movement in 1955, the number 5516 watch is the first perpetual calendar watch to join the leap year display. Audemars Piguet has several key points in the development of the perpetual calendar function: the display of the leap year, the addition of a convenient automatic winding device and the breakthrough of the ultra-thin perpetual calendar. The 5516 is a milestone model of the 13VZSSQP manual winding perpetual calendar movement after the full-calendar calibre of 10GHSM, 13VZAQ, 9/10RSQ, etc. The 5516 is not only the first wrist to incorporate the leap year display into the perpetual calendar function, but also almost made the leap year display an important watch for the basic calendar of the future.
