For the first time, the 41 mm case and bracelet of fake Audemars Piguet‘s iconic Royal Oak Perpetual Calendar have been entirely finished in blue ceramic which, in addition to making it perhaps even more beautiful in my humble opinion, reduces it even more. thickness (now measures only 9.5mm thick). Not everyone knows that ceramics require precise processing: the Zirconium Oxide (ZrO2) powder, modified to obtain a blue pigmentation once fired, is mixed with the appropriate agglomerant before being transformed into ceramic. The components reach the final color only after being sintered at more than 1,400 ° C. And that’s not all, because the final color of the ceramic depends on the sintering temperature, which does not allow for variations. The alternation of satin and polished bevels, a distinctive feature of the Manufacture, was instead applied by hand with extreme care. The indexes are applied in 18-karat white gold and the faceted hands are equipped with a luminescent coating that makes them visible in the dark. The three calendar counters and the opening for the moon phases make the dial balanced, while ensuring excellent readability of hours, minutes, day, date, week, month, astronomical moon and leap year indication. This new model is equipped with the self-winding Caliber 5134 which automatically takes into account the number of days in the month and correctly displays the prevailing date even in leap years. Suppose you always keep the clock in charge: the date will not require any manual adjustment until 2100 to stay in line with the Gregorian calendar! Launched in 2015, this 4.3mm-thick movement required the reorganization of numerous components, including the 22-karat gold skeletonized oscillating weight. The bulkier part of the rotor was positioned on its outer edge which is recessed inside a channel that surrounds the movement, thus allowing the height to be reduced. Likewise, the choice of a suspended barrel helped to reduce the thickness of the movement. The sapphire crystal caseback reveals the traditional Haute Horlogerie decorations that embellish Caliber 5134: Côtes de Genève, circular grain, brushed with a soleil motif and polished bevels. Audemars Piguet’s first full calendar wristwatch was put into production in 1921. From 1921 to 1970, 188 full calendar wristwatches were produced, a small part of the total production of the Manufacture in those years. In 1955, the company launched the world’s first perpetual calendar wristwatch with a leap year indication, of which 9 were created between 1955 and 1957. The brand managed to break another record in 1978, at its peak. of the quartz crisis, when it launched the world’s thinnest self-winding perpetual calendar wristwatch of its era (3.95 mm) using the extra-flat Caliber 2120, launched in 1967, as a base. put into production a total of 7,219 perpetual calendar wristwatches equipped with this caliber. Launched in 2015, Caliber 5134 adapted the perpetual calendar movement to a larger diameter than the 41mm Royal Oak case (Model 26574), while maintaining a flat profile at 4.3mm thick. In 2018, the Manufacture opened another chapter in its history of perpetual calendar timepieces with the arrival of the revolutionary Royal Oak Automatic Perpetual Calendar Extra-Flat 41mm, known as RD # 2 – the automatic calendar wristwatch. thinnest perpetual in the world at the time of its launch. This 6.3mm-thick watch features Caliber 5133, a newly developed ultra-thin movement measuring just 2.89mm in height, heralding once again a new generation of astronomical watches. The watch has about 40 hours of power reserve, is water resistant to 20 meters and is completed by a blue ceramic bracelet with a titanium AP folding clasp.rolex replica
