Established ‘Attractive Studio’ to engage in professional copywriting, consulting, and lectures. The classic status of Audemars Piguet’s Royal Oak series is beyond doubt. The case is full of fine details and polished. The unique appearance has always been at the forefront of the trend, but there is a more classic function in the Royal Oak series. You ca n’t Don’t understand. In the last article of Audemars Piguet and Yuyi Watch Cooperative Limited Perpetual Calendar, the distinction between the Royal Oak series and the Royal Oak offshore type series was mentioned. There is a very important key. In addition to the different details of the case design, The shore series tends to be more sporty, while the Royal Oak series has a more classic performance. Therefore, the design and smoothness of the case are more refined than the rough ore and strength of the offshore series. Therefore, the Royal Oak series Even if complicated functions are added, they still have to maintain a considerable thinness, so that the overall model is not too large and more suitable for formal wear and multiple occasions. The Royal Oak series is suitable for formal and multiple occasions. One of the most classic features of the Royal Oak series is the perpetual calendar. The Hong Kong and Macau distributor Yuyi Watches collaborated with Audemars Piguet for the first time in a limited edition of 50 pieces. In addition, it is also paired with a rare green faceplate, which has become a special highlight in the Audemars Piguet Royal Oak Perpetual Calendar watch. Audemars Piguet Royal Oak Perpetual Calendar is a limited edition watch. Perpetual calendar display is the most relevant function of astronomy and time in all mechanical movement designs. The perpetual calendar is a romantic and emotional mechanical function for me: humans observe astronomical phenomena and begin to record the regular changes of nature and time, further dividing the time we use into daily hours and minutes , Second, and then the month, week, and date. Later, I discovered the strange orbit irregularity of the astral movement, and then I knew how to calculate the leap year. The perpetual calendar normalizes the movement of celestial bodies into complicated gears after actuarial calculation, and then displays them on the watch hourly. This reflects the interrelationship between human and nature. In the mechanical movement, a series of mathematical and mechanical engineering procedures must be used to interconnect the multiples of gears and the shape of the gears to show the time rule planned by humans. Perpetual calendar , Moon phase display and so on were born. Audemars Piguet Royal Oak Perpetual Calendar is a limited edition watch. The classic and practical perpetual calendar Audemars Piguet put the leap year display into the perpetual calendar watch movement as early as 1955. The watch number 5516 was the first perpetual calendar watch with the leap year display. Audemars Piguet has several important points in the development of the perpetual calendar function: Insert the leap year display , add convenient automatic winding device , and ultra-thin perpetual calendar breakthrough. 5516 is a milestone model equipped with the 13VZSSQP manual-winding perpetual calendar movement after the all-calendar movements such as 10GHSM, 13VZAQ, 9 / 10RSQ, etc. 5516 is not only the first wrist to incorporate leap year display into the perpetual calendar function The watch has almost made the leap year display an important model for basic perpetual calendar watches. Audemars Piguet’s first 5516 perpetual calendar watch with leap year display. The classic symbol of the legendary perpetual calendar movement. The invention of the quartz movement in 1980 set off a storm of survival of mechanical clocks. At this time, the birth of Audemars Piguet 2120/2800 movement has an extremely important key role. In the era when watches and clocks may be completely replaced by quartz clocks, Audemars Piguet launched the market with the complex function of perpetual calendar to prove that complex mechanical movements have great potential. The 2120/2800 introduced in 1978 is an extremely classic perpetual calendar movement in the minds of many collectors. This self-winding perpetual calendar movement based on the LeCoultre movement (type 2120) was served by Audemars Piguet at the time. The master watchmaker Michel Rochat of the year secretly carried out the research and development plan, and cooperated with Jean-Daniel Golay and Wilfred Berney to add a perpetual calendar module on the basis of the 2120 movement. This was also the world’s thinnest automatic winding perpetual calendar machine at the time. Core: only 3.95 mm. Audemars Piguet is equipped with a classic 2120/2800 million calendar movement for many years. The perpetual calendar has always been regarded as one of the three complicated functions. Until the release of 2120/2800 in 1978, only Patek Philippe and Audemars Piguet had launched perpetual calendar watches. It can be seen that 2120/2800 added such complex mechanical functions as the perpetual calendar to the automatic winding. Convenient to use, how important it was to boost the momentum and development prospects of the watch industry at the time. The first batch of watches equipped with 2120/2800 self-winding perpetual calendar movements received 159 commissioned production orders after its introduction, which is almost the total number of calendar display watches produced by Audemars Piguet since 1924. The announcement of 2120/2800 not only represents the precursor of prosperity for the entire Swiss watchmaking industry, but also creates a flourishing foundation for watchmaking and brands for Audemars Piguet, and pushes Audemars Piguet’s status in the production of complex-function watches. Top position. Audemars Piguet’s first Royal Oak Perpetual Calendar with Ref. 2120/2800 (Ref. 5554). Although the 2120/2800 is a classic and most praised ultra-thin self-winding perpetual calendar movement, the diameter of the case mounted on the Royal Oak Perpetual Calendar watch can only reach 39 mm. At the same time, the following models are trending towards larger diameters. Speaking slightly, and the background based on LeCoultre also makes people look forward to the launch of Audemars Piguet’s new perpetual calendar movement. In 2015, the 5134 automatic calendar movement was launched. All the configurations and designs are almost the same as those of the 2120/2800 movement of the year. It is only 1 mm more in diameter and 4.31 mm thicker. In 2015, Audemars Piguet launched a newly developed 51.34 million calendar caliber. The classic undefeated status of the 2120/2800 movement allowed Audemars Piguet to choose to follow most of its design features: the now uncommon 2.75 Hz frequency (19,800 oscillations per hour) still only maintains a power reserve of 40 hours, The overhanging barrel without fixed upper bridge is designed to maintain the overall thinness. In addition, the 5134 movement has several technical highlights: two-way automatic winding and 317 days in 125 years. It only needs to be adjusted once. Precise moon phase display. In the design of the movement, similar to the classic features of 2120/2800, the 5134 movement uses a more classical adjustable weight balance. Although the configuration of the movement is almost the same, the 5134 is only one millimeter in diameter, but it allows The new 41mm Royal Oak Perpetual Calendar watch has a new face. 5134 million calendar movement exploded view. The classic symbol of the green face plate is limited by the Hong Kong and Macau distributor Yuyi Watches and Audemars Piguet. It chose the very rare green faceplate of Audemars Piguet watches, and matched the Audemars Piguet exclusive ‘Grande’ designed for the Royal Oak series. Tapisserie ‘large checkered decoration, deep green is also rarely seen in the design of watches and clocks, the choice of green stems from Audemars Piguet and Yuyi Watch’s long-established brand representative colors, which also symbolizes the two Friendship. At 6 o’clock, the moon phase disk is blue sandstone, with a realistic moon printed on it. The sand moonstone blue moon phase disc used in the 5134 movement contrasts with the true green color selected this time, as if looking up into the dark blue sky just before entering the night in the forest. Coupled with the more spacious layout of the 5134 movement, the four full calendar display circles are more open and enchanting. Perpetual calendar functions Each display disk is harmoniously and inconspicuously placed around the deep green disk. The moon phase disk is decorated with radial patterns. The bright yellow central axis pointer indicates the weekly calendar function only perpetual with 5134 movement. A bright yellow arrow-shaped pointer indicates the weekly calendar function. The movement 5134 has an additional 52-week weekday indicator, which is displayed at the outermost part of the faceplate. This is also an extremely rare design in the perpetual calendar model. It is like the basic equipment display function that redefines the perpetual calendar in the 1950s. . The weekly calendar is marked around the outer edge of the faceplate. The layout of the 5134 perpetual calendar movement is not only compared to the past perpetual calendar, but also has a wider and more mature face. The function of the weekly calendar display is also the first of its kind for the perpetual calendar model. The central pointer design increases the complexity of the overall dial. Under the consideration of function, at the same time, the aesthetics and complexity are perfectly balanced. Audemars Piguet Royal Oak Perpetual Calendar One Limited Edition comes with a green leather strap for replacement. I have always thought that the more complicated the display panel, the more it is necessary to pay attention to the configuration and space between each indicator needle circle. The difference can be thousands of miles. I prefer the multi-needle design, which deviates from the central axis and maintains a delicate circumferential space with the outermost edge of the face plate, but is properly and firmly balanced. The 41 mm Royal Oak Perpetual Calendar watch is just such a big thing. Audemars Piguet’s self-made 5134 caliber is giving this watch an extraordinary soul, but the unique green dial of the Royal Oak Perpetual Calendar Limited Edition launched by Audemars Piguet in collaboration with Yuyi Watches highlights the stylish design of Dotted Point, a global limited edition Fifty pieces are only available at Audemars Piguet stores operated by Yuyi Watches in Hong Kong and Macau.
