Audemars Piguet studied the complex function of perpetual calendar in 2016, releasing a brand new movement calibre 5134 which is developed on basis of the legendary ultra thin Cal.2120. The complex movement calibre 5134 was firstly used in Royal Oak collection, the most popular collection of the brand. The ultra thin watches are popular among all the styles for the wearing comfort and design aesthetics. However, the watches with complex functions are difficult to be created in a ultra thin case.
This year Audemars Piguet developed the brand new movement calibre 5133 with an incredible thickness which is only 2.89mm, becoming the thinnest movement with perpetual calendar function. Therefore, the Audemars Piguet Royal Oak fake watch with platinum case becomes the thinnest perpetual calendar automatic watch in the world, which is only 6.2 mm.
In order to maintain the reliability and stability of the thinnest movement, Audemars Piguet firstly uses the dial as the main splint of the movement, then integrates the month-end cam on the month gear, making the traditional 3-layer perpetual calendar movement structure realize a single-layer structure, reducing some fixed parts of the 3-layer structure. It not only reduces the thickness of the movement, but also makes the gear and cam layout more compact and stable. 41 mm Audemars Piguet knockoff watch features a classic blue Grande Tapisserie dial adorned with the three brighter sub-dials, making each function with ultra legibility.
