Classic Symbol Two: Legendary Perpetual Calendar Movement
The invention of the quartz movement in 1980 setting off a storm of mechanical clocks. At this time, the birth of the Audemars Piguet 2120/2800 movement has an extremely important key role. In the era when mechanical clocks could be completely replaced by quartz clocks, Audemars Piguet introduced the Perpetual Calendar function in the market to prove that complex mechanical movements are promising. Introduced in 1978, the 2120/2800 is an extremely classic perpetual movement in the minds of many collectors. This self-winding Perpetual Calendar movement based on the LeCoultre movement (2120) was serviced by Audemars Piguet at the time. Michel Rochat, the master watchmaker of the year, secretly carried out research and development projects, and cooperated with Jean-Daniel Golay and Wilfred Berney to add the Perpetual Calendar module to the 2120 movement, which was the world’s thinnest self-winding Perpetual Calendar watch: only 3.95 mm in thickness.

In 2015, the 5134 automatic winding perpetual calendar movement was launched. All the configurations and designs were almost the same as the 2120/2800 movements, but it only increased the diameter by 1 mm and the thickness increased to 4.31 mm.

Classic Symbol Three: Green Dial
This limited edition chooses the green dial that is very rare under Audemars Piguet’s watches, and it is designed with the “Grande Tapisserie” large plaid decoration designed by Audemars Piguet for the Royal Oak series. The deep green is rarely seen in the watch design. The choice of green color is derived from the brand representative color of both the Audemars Piguet and the Unique Timepiece, symbolizing the friendship between the two.
The Moon Phase at 6 O’clock
In the 5134 movement, the blue moon phase is matched with the green dial, as if in the forest, looking up at the dark blue sky that is about to enter the night. Coupled with the more spacious layout of the 5134 movement, the four full calendar display circles are more fascinating. The perpetual calendar functions are displayed in a harmonious and unobtrusive position on the deep green dial. The moon phase sub-dial is decorated with radiation patterns, and the yellow center axis hands indicates the weekly calendar function of the perpetual calendar with the 5134 movement.
A Sharp Yellow Arrow Pointer Indicates the Weekly Calendar Function
The 5134 movement has an additional 52-week weekly calendar indicator, which is displayed on the outermost surface of the dial, which is also an extremely rare design in the perpetual calendar. It is like the basic display function of Audemars Piguet redefined the perpetual calendar in the 1950s.
The Weekly Calendar Is Wrapped Around the Outer Edge of the Dial
The layout of the perpetual calendar 5134 calibre movement is broader and maturer than the perpetual calendar in the past. The function of the weekly calendar is also the first for the perpetual calendar. The central pointer design will increase the complexity of the overall dial. In terms of functional considerations, at the same time, aesthetics and complexity are perfectly balanced.

I always think that the more complicated the display is on the dial, it is more important to pay attention to the configuration and space between each indicator pin circle, and the difference can be a thousand miles. I prefer a multi-hands design that deviates from the central axis and maintains a subtle circumferential space with the outermost edge of the dial, but is properly balanced, and the 41 mm Royal Oak Perpetual Calendar is just such a big deal. Audemars Piguet’s self-made 5134 calibre is giving this watch an extraordinary soul. It is the limited edition of the Royal Oak Perpetual Calendar, which is launched by Audemars Piguet and the Unique Timepiece. The unique green dial makes the design of the point highlight the fashion atmosphere, limited to 50 pieces.
