Audemars Piguet Royal Oak Ultra-Thin Perpetual Calendar

There are two reasons why the Audemars Piguet Royal Oak Ultra-Thin Perpetual Calendar is so "magical":

1. The Audemars Piguet Royal Oak Ultra-Thin Perpetual Calendar, with a thickness of 6.2 mm, breaks the world record and is the thinnest perpetual calendar among famous watches.

2. The Audemars Piguet Royal Oak Ultra-Thin Perpetual Calendar directly mass-produces the Audemars Piguet RD2 concept watch, which is exactly the same as the concept watch.

In 2018, Audemars Piguet launched the ultra-thin perpetual calendar concept watch RD2. A year later, Audemars Piguet directly mass-produced the concept watch RD2, which is now the Royal Oak ultra-thin perpetual calendar. From the concept watch to the mass-produced version, the appearance and movement are completely inherited without any shrinkage. Audemars Piguet's original purpose was to make an ultra-thin, cuff-in, easy-to-read and durable perpetual calendar watch. In the process, a new perpetual calendar movement structure was used. In the end, even Audemars Piguet itself did not expect that it would break the world record for the thinnest perpetual calendar.

The Audemars Piguet Royal Oak Ultra-Thin Perpetual Calendar became the world's first, mainly thanks to the Audemars Piguet 5133 perpetual calendar movement. The 5133 movement, developed by the Audemars Piguet APRP movement factory (specializing in the development of complex watches), is developed on the basis of the Audemars Piguet 2120 automatic movement, with a swing frequency of 19,800 times/hour and a power of 40 hours. (The 2120 movement, namely the Jaeger-LeCoultre 920 movement, has been used by Audemars Piguet since the 1970s. Audemars Piguet obtained the copyright of the Jaeger-LeCoultre 920 movement in 2001).
