Audemars Piguet RD Plan

RD plan, the two abbreviations stand for Research and Development respectively. Audemars Piguet aims to break through the limitations of watchmaking technology through experimental technology, so as long as an Audemars Piguet watch has RD in its name, it means that this watch represents love. The highest level of watchmaking technology. This series has released a total of four watches so far, each with its own uniqueness, RD#1 super minute repeater watch, RD#2 ultra-thin perpetual calendar, RD#3 ultra-thin tourbillon, and the one launched last year. The masterpiece is the RD#4 extraordinary complex watch. Each one allows Audemars Piguet to once again achieve technological breakthroughs and industry firsts.

The perpetual calendar, through the movement of the precision mechanical structure of the movement, realizes the automatic differentiation of leap years and large and small months, so it is also known as the most practical complex function. As the perpetual calendar has developed to this day, the major brands compete in two directions, the disk layout and the convenience of adjustment functions. For example, the Audemars Piguet perpetual calendar disk layout is clear, highly legible, and good-looking enough. After all, Audemars Piguet established the display layout pattern of modern perpetual calendar watches in the watchmaking field in the 1950s.

And Audemars Piguet has devoted a lot of effort in this work to conduct in-depth research and development in the ultra-thin direction to make the watch more wearable. In 2018, Audemars Piguet launched the Royal Oak RD#2 ultra-thin perpetual calendar watch. After five years of research and development, it "accidentally" became the world's first, becoming the world's thinnest self-winding perpetual calendar watch at the time. , and won the 2019 GPHG Golden Pointer Award in one fell swoop.

In fact, many brands are making ultra-thin perpetual calendars, so why is Audemars Piguet so good? Because Audemars Piguet really follows the idea of making ultra-thin watches and directly changes the production model of conventional perpetual calendars by superimposing perpetual calendar modules on conventional movements, which are stacked with multi-layer structures. Conventional perpetual calendar watches generally have a three-layer structure, with leap year and 24-hour day and night displays on the upper layer. However, Audemars Piguet has directly reduced the three layers through two important improvements and the reuse of movement space. One level.

The two most important improvements, officially called integrated gears, incorporate the end-of-month date cam into the date wheel and the month cam into the month wheel. It sounds simple, but everyone knows that addition is easy but subtraction is not. In fact, it is very technically challenging. Audemars Piguet wants to change the conventional perpetual calendar structure. The perpetual calendar is a preset calculation mode between the gears. Moving one part is equivalent to recalculating it. It is not easy to redo it. Audemars Piguet uses a date gear with a special notch. The new notch can drive the month forward, thereby replacing the original date cam. At the same time, it directly overturns and redoes the 48-month program wheel at the core of the perpetual calendar, reducing it to a single-layer gear. thickness of.

In order to be thinner, Audemars Piguet no longer uses a perpetual calendar module, and directly installs the perpetual calendar parts on the lower layer of the basic movement of the 5133 movement, Audemars Piguet's classic 2120 ultra-thin automatic movement, to reduce the thickness.
