Brand Patek Philippe’s New 5204 Perpetual Calendar Double-second Chronograph Stopwatch

Since the establishment of Patek Philippe, chronographs and stopwatches have been playing an important role in the brand’s complex performance timepieces. Most of the noble chronographs are treasured by museums in the world, while a few works handed down by the market have become connoisseur’s treasures. The first chronograph stopwatch made by Patek Philippe came out in 1856, the pocket watch numbered 10051. Large seconds and lightning hands (seconde foudroyante) are available; the watch part is a two-second chronograph stopwatch from 1923. In the 1930s, the Stern family became the owner of Patek Philippe, and the 130 chronograph watch launched by the brand was very popular in the market. In 1986, Patek Philippe adopted the Nouvelle Lemania-based movement to create the CH 27-70 known as the most exquisite hand-made chronograph movement of this century. It also shaped Patek Philippe’s chronograph legend in recent decades.
    Traditionally, Patek Philippe’s classic chronograph stopwatches have been introduced one by one in the following three categories: simple chronograph stopwatch, perpetual calendar performance chronograph stopwatch and dual-hand chronograph stopwatch with perpetual calendar performance. With the turbulence of self-made movements, Patek Philippe’s new CH 29-535 PS hand-finished movement finally came out in 2009, and it was unexpectedly paired with 7071R ladies’ watches for the first time. The CH 29-535 PS hand-finished movement is completely self-made by Patek Philippe. It is equipped with a classic column wheel device and a horizontal clutch. It also has six patented innovations and many technical improvements. Following the 7071R, Patek Philippe immediately released this year’s first 5170J men’s watch with this movement, and then in 2011 presented a 52.7 million calendar chronograph stopwatch. This year, Patek Philippe now launches the latest series in the series, presenting a chronograph stopwatch with a number of 52.04 million perpetual calendar. It starts with a brand new movement, CHR 29-535 PS Q, developed by Patek Philippe Workshop.
    Earlier than two years ago, watch connoisseurs and collectors had a lot of discussions. It is speculated that Patek Philippe will be based on the hand-made patented CH 29-535 PS movement, to create a new two-second chronograph stopwatch to replace the number 5004. Wristwatch; No. 5004 Two-second chronograph stopwatch adopts the classic hand-wound movement design, which is controlled by a column wheel and a horizontal clutch. It also has a perpetual calendar device that people desire. However, even if the experts did not expect it, the brand could immediately complete a complete series of chronographs developed in-house. In fact, the practice of Patek Philippe’s annual chronograph is to quickly make a complete chronograph series with a new patented movement, which has repeatedly demonstrated the strength of this family-owned independent watch manufacturer. Now, this grand plan is finally completed.
    For decades, Patek Philippe has focused on internally developed movements and infused the brand’s unparalleled characteristics. This practice has always been one exception: Before the introduction of the CH 29-535 PS chronograph movement, Patek Philippe’s chronograph stopwatches were all made from 27- 70 movement drive. The movement was then revised by Nouvelle Lémania in accordance with Patek Philippe’s specifications, made into a semi-finished movement, only for the brand, and then assembled and completed in Geneva. The 27-70 movement is revered by time-loving people and regarded as the best and beautiful chronograph movement in the world.
    CHR 29-535 PS Q movement, hand-wound ultra-thin mechanical movement, dual-hand chronograph stopwatch device driven by two column wheels, chronograph seconds hand and dual-hand chronograph seconds hand, 30-minute instant jump calculator, small three hands Sub display panel. Perpetual calendar performance, display day, month, leap year cycle and day / night display, pointer date display; moon phase display; diameter: 32 mm; thickness 8.70 mm (perpetual calendar device accounts for 1.65 mm, dual needle seconds device accounts for 1.7 Millimeters); number of parts 496 (182 perpetual calendar devices, 42 needle-secondary devices with isolators); 34 gems; 65 hours power reserve.
    With the advent of the new millennium, the benchmark position of the 27-70 movement gradually abdicated. It was due to the active measures of Patek Philippe to launch a chronograph stopwatch, which led to the introduction of the CHR 27-525 PS movement in 2005, becoming the world’s thinnest. Double-second chronograph stopwatch movement; the brand then launched the CH 28-520 IRM QA 24H self-winding chronograph stopwatch movement with patented perpetual calendar in 2006; the CH 29-535 PS hand-winding chronograph was launched in 2009 Stopwatch movement, controlled by column wheel, equipped with lateral clutch. All movements received unanimous praise from all sectors of the watch industry, marking the successful completion of the entire task. Such a good performance also lays the foundation for the brand. Based on its patented movement, it has made a variety of chronograph stopwatch movements with varying degrees of complexity, which enriches the full range of classic chronograph stopwatch series. Including the three chronograph basic movements and the chronograph components of the triple complex performance watch No. 5208, Patek Philippe introduced the eight chronograph movements in just six years. It is a record and applauding. Eight chronograph movements belong to one of the brand’s existing more than fifty movements. All movements are developed and produced in-house, including 17 basic wristwatch movements, multiple simple-winding and automatic winding movements, and movements with tourbillons, patented annual calendar devices, minute repeaters and other astronomical devices, etc. .
    Patek Philippe’s new dual-second chronograph chronograph with perpetual calendar display features all the traditional outstanding features, including hand-winding, two column wheels and lateral clutches, which are well received by true watch connoisseurs. The watch is also the most modern symbol of its category, only because the CH29-535 PS basic movement gathers six patented innovative designs (the appendix has brief data), and it is also the first to appear in the watch number 5270 in 2011 Perpetual calendar device. The new CHR 29-535 PS Q dual-hand chronograph stopwatch movement beats at a frequency of 28,800 (four Hz) per hour, with a 30-minute skip calculator and a small three-hand running Attached display disk, power reserve is 65 hours. Patek Philippe has completely renovated the dual-hand chronograph device, adding two technical innovations: replacing the dual-hand chronograph lever with an innovative isolator; and using a new mechanism to be patented, which makes the dual-hand chronograph second hand and chronograph second hand superimposed accurate.
Isolator for double-handed seconds lever
    Whenever the chronograph second hand stops to indicate a certain elapsed time, the isolator of the chronograph second lever is separated from the chronograph second gear. This interrupts the contact between the dual-hand chronograph lever and the heart-shaped cam, and the stopped dual-hand chronograph gear cannot affect the swing of the balance wheel. The wheel hub of the guide post is carefully polished, which is regarded as Patek Philippe’s well-respected watchmaking tradition. The column wheel cap of the new CH 29-535 PS basic chronograph movement and the performance of the negative eccentric component allow for more precise adjustments, unparalleled. The double-needle chronograph column wheel has additional performance, and a gooseneck accessory is combined to play the role of an isolator spring.
2. New device to reduce the problem of overlapping deviation between the double chronograph second hand and the chronograph second hand
    The two-hand chronograph chronograph has two central seconds hands: the two-hand trotteuse and the rattrapante. The two-hand chronograph gear connected to the two-hand chronograph seconds hand rotates with the chronograph gear carrying the chronograph seconds hand; both gears are connected to a heart-shaped cam, which is fixed on the chronograph gear. As is the case with all mechanical connections, the ruby ​​rolling bearing with double needle seconds lever requires a little room for movement to work without interruption. However, the active space will slightly offset the position of the dual chronograph second hand, resulting in the two hands not overlapping accurately. According to the convention, as long as the area of ​​the chronograph second hand is widened slightly, it is enough to hide the overlap deviation, which is not a major disadvantage. However, this violates Patek Philippe’s consistent principle of perfection. The movement engineer of the workshop developed an innovative solution and filed a patent application.
    The new gooseneck-type isolator device consists of forty-two parts and has a height of 1.7 mm, which is about 0.1 mm thinner than the isolator device of the watch number 5004. In comparison, the movement of the new 5204 watch is 8.7 mm thick, and the movement of the 5004 watch is 8.86 meters thick.
    Patek Philippe’s new dual-hand chronograph chronograph has perpetual calendar performance. The overall thickness of the watch movement is 8.7 mm, while the perpetual calendar device only accounts for 1.65 mm, which shows the watchmaker’s ability to handle complex parts, including large levers, dates Gears, week and month star gears, leap year cams, lever springs and other precision components. Looking at Patek Philippe’s various timepieces, these parts are not only made with precision, but also carefully polished. For example, the angle grooves are slightly recessed and carefully polished, the sides are polished by human hands, and the surface shows the effect of straight grain processing. Steel gears are as meticulous as the ten-lobed gears: all gear teeth and blade gear teeth are polished by hand with hardwood grinding wheels one by one. This procedure is not purely for aesthetics. Rather, it takes into account that smooth surfaces can reduce friction and wear of parts, making kinetic energy transmission more efficient.
    The watch contains a sophisticated gear set, a two-hand chronograph stopwatch device and a perpetual calendar device, which are sophisticated and complex, but do not interfere with the layout of the twelve individual displays on the surface, which is methodical and clear and easy to read. Like the 5270, the new watch follows the classic chronograph surface design of Patek Philippe with calendar performance, but with the addition of a two-hand chronograph second hand. The surface layout is loyal to tradition. There are double display windows side by side at twelve o’clock, showing the day of the week and the month, respectively; the pointer-type date display combined with the moon phase display is set at six o’clock. The small three-pin auxiliary display dial works continuously, and the thirty-minute jump indicator is located at 9 o’clock and 3 o’clock respectively, and the center points of the two are moved to a range slightly below the horizontal centerline of the main surface. This layout is a typical design feature of the movement. In addition, there are small circular display windows at 4 to 5 o’clock on the surface to display the leap year cycle; and a day / night display at 7 to 8 o’clock, which simplifies the process of correcting the date performance. The silver-tone milky white surface is made of 18K gold, with twelve Barton-style platinum hour markers, and the surface is coated with luminous materials. The black hour and minute hands are also superluminova, which is very clear when reading in black. The surface layout is ingenious, like an elegant stage, showing the most popular and practical performance displays of top sophisticated watches.
    The new watch number 5204 is a perfect example of the Patek Philippe classic chronograph trilogy. It is herewith a platinum case with a diameter of 40 mm and a thickness of 14.19 mm. The case is composed of three parts, with rounded lines and beautiful lugs, straight lugs, and a concave ring embraces an arched mirror. There are two case backs, platinum and sapphire glass, for conversion. The platinum material is extremely hard to cut and shape, and it is a challenge to pay attention to the superb craftsmanship of the watch case. Compared to traditional case materials such as gold and steel, the process of shaping the platinum case will also place great pressure on the tool. Even though the process is arduous, in the end, an excellent case can be achieved, revealing an unparalleled type of cool silver light, with a generous amount, enough to let people see the touch, and truly appreciate the extraordinary status of the timepiece. Like all Patek Philippe platinum timepieces, the watch case is set with a top-notch Wesselton diamond at six o’clock between the lugs to identify the platinum material, which can only be seen by the watch owner. There are round start and stop buttons at the 2 o’clock and 4 o’clock positions of the watch body. The watch is also different from its simple chronograph stopwatch with a perpetual calendar. The crown has special buttons for controlling the two-hand chronograph seconds hand. No. 5204 Double-handed chronograph stopwatch with perpetual calendar performance, handcrafted in accordance with the requirements of the Patek Philippe imprint, with a matte black alligator leather strap showing a square texture, hand-sewn, and platinum folding buckle The watch is easy to wear and comfortable.
