The “old” Royal Oak Perpetual Calendar today is an iconic watch, but simply to small for many potential buyers. The new sizes 41 mm / 9,5 mm seem to be perfect, have a look …

 

At the time being Audemars Piguet was one of the first Swiss manufacturers to present this nice and useful complication in a sports watch with a metal bracelet. The remarkable ultra-thin case of the Royal Oak and its iconic design by Gerald Genta since then are well known to collectors and watch aficionados worldwide. No doubt, perpetual calendars are part of the DNA of Audemars Piguet.

In 2015 the Royal Oak Perpetual Calendar returns to center stage with four different versions (two in steel, two in pink gold).

Continuing the shift in watch case size that began in 2012, the new Royal Oak Perpetual Calendar now measures 41 mm and is with 9,5 mm yet still extremely thin. The “old” Royal Oak Perpetual Calendar measured  39 mm / 9,3 mm …

The enlarged size has resulted in a “Grande Tapisserie” dial design that increases the overall aesthetics, balance and legibility of the perpetual calendar indications.

The layout of the dial includes all of the traditional indications of a perpetual calendar watch: day, date, detailed astronomical moon, month and leap year.

In addition the Royal Oak Perpetual Calendar indicates the 52 weeks of the year by an outer chapter ring (the so called rehaut of the dial) with a corresponding central hand. This adds another layer of time measurement to this exceptional timepiece.

Did you know, that the thinner the movement, the more complex it is to adjust and assemble its parts as it requires extraordinary skills to work on components which are sometimes as thin as a human hair. Audemars Piguet masters these watchmaking challenges; all finishing operations are performed by hand in accordance with the highest standards of fine watchmaking or “Haute Horlogerie” as the Swiss say in the French speaking part of Switzerland.

What is a perpetual calendar?

A perpetual calendar watch is a pretty complex micro-mechanical device that has been engineered to automatically adjust to the varying number of days in each month, and even to the leap year. The watch knows that February has 28 days for three consecutive years prior to the leap year when the 29th day is added. It is in many regards an analog computer as it calculates or computes the complexities of the calendar independently from the user, taking automatic account of months with 28, 29, 30 and 31 days.

  • Hi Alexander,
    do you have any idea why the balance ticks so slow – only 2,75H versus today’s standard of 4H?
    Thanks, Tom.

  • As far as I can recall the measurement of old Audemars Piguet Royal Oak Perpetual Calendar used to be 39-mm / 9.3-mm and this latest version of Audemars Piguet Royal Oak Perpetual Calendar would measure 41-mm / 9.5-mm, so the difference between the 2 versions would be only 2-mm / 0.2-mm, which is very little.

    Anyway, enjoyed these XL sized pictures immensely, thanks!

    • I agree, 41-mm seems like such a minimal broadening. My Jaeger-LeCoultre Diving Chrono is 44-mm and in my opinion that’s a perfect size. Or the slightly smaller Ulysses Nardin Marine Maxi at 42.7-mm is also a great size. 41-mm is just a hair larger than the older Rolex subs.
