    Gp Girard Perregaux Constant Power Escapement Watch Is Officially Launched. Epoch-making Technology Breakthrough Makes Its Debut

    GP Girard-Perregaux released a prototype of Constant Escapement a few years ago, which shocked many watch art connoisseurs; GP Girard-Perregaux’s five-year research and development revolutionized the technology A field of technology that has never been involved in watchmaking, it is now officially assembled in the Haute Horlogerie series, writing an important chapter in the research on the stability of escapement systems.

     Girard-Perregaux named Constant Escapement Constant Escapement to pay tribute to the founder Constant Girard-Perregaux, whose name is in keeping with the technical challenge that has plagued watchmakers for centuries-constant force By coincidence, Girard Perregaux was determined to develop a constant-power escapement technology with a revolutionary concept.

     Five years ago GP Girard-Perregaux published a constant-power escapement that was exciting. The extremely lightweight escapement was not only beautiful, but also had great potential for practical application. It is the ultimate precision of mechanical watches pursued by the watchmaking industry in the century. And stability, providing a new and reliable technical solution.

     To understand the importance of constant-power escapement technology, first return to the basic principle of mechanical watch operation: the escapement structure regularly transmits the energy of the barrel to the drive wheel system and controls the speed of the pointer operation, just like a faucet controls water Throat output is the same.

     The key to the entire power transmission process is not the escapement speed or wobble frequency, but its stability: no matter whether the wobble frequency is three or four times per second or even a thousand times, the accuracy of the travel time is ultimately tied to the wobble frequency, which can maintain stability for a long time.

     Many escapement structures have appeared in the past few hundred years, and they did not become mainstream until the introduction of Swiss lever escapement technology. Most mechanical watches still use this technology today. However, the Swiss lever escapement has a disadvantage, that is, how much power is transmitted from the barrel. It can only send the same power to the balance wheel. The problem is that the power of the barrel is slowly consumed, and the stable power is precisely timed. The key is that the power decreases, and the balance of the balance wheel also decreases. As the watch lacks power, the accuracy of the travel time is difficult to maintain. This phenomenon can be said to be a mantra that troubles the watchmaker.

     The principle of the constant power escapement system is that it can output stable and constant power to the balance wheel no matter how much power is transmitted from the barrel. GP Girard-Perregaux’s revolutionary technology is to add a very thin elastic silicon hairspring to the escapement system, which can store energy within a certain limit. When approaching a stable threshold, a hairspring appears. The unstable state, and the energy is sent out in real time in the form of wave vibration, and it repeatedly provides stable and average power to the balance wheel.

     You can understand this process visually: Hold a business card vertically with your thumb and forefinger, apply a little pressure to bend the business card into a left-opening bracket “(), and then apply pressure to the bent side to a certain limit. The business card will snap and bend in the other direction, and it will turn into the opposite right-closed bracket ”. Try everything.

     This phenomenon is called buckling, and GP Girard-Perregaux hairspring experts extended it to the concept of buckling hairspring: an elastic silicon hairspring as thin as six points and one hair plays the role of energy storage. The wheel has very little power, and when it reaches the critical point, it bends to the other side and sends the power back to the balance wheel. This process is not affected by the change of the spring power, and the same power is output to the balance wheel every time.

     Most of the constant power technology in the past is the average value of the total power over a period of time, but the Girard-Perregaux technology is a real-time, constant and constant-power escapement in real time, and can be measured by laboratory test methods.

     The constant power escapement of GP Girard Perregaux is a symmetrical structure, but it is not an aesthetic consideration. Instead, it can balance the power in the center of the balance wheel, so that the balance wheel can rotate completely smoothly.

     Both ends of the hairspring are fixed on the frame, and the hairspring and the frame are integrally formed by a silicon crystal. This structure can accurately connect the power contact points and bend the hairspring to the other side. Although the principle is simple, it requires extremely high accuracy in practice. Without silicon crystal technology and DRIE etching technology, it would be difficult to achieve. Girard-Perregaux collaborated with Swiss Electronics and Micro-engineering Centre in Neuchâtel, Switzerland. The watchmakers and physicists on both sides went through complex calculation procedures to determine the characteristics of the hairspring and the factors affecting the bending point, and finally decided to integrate them. The forming technology makes the hairspring vibrate as if floating in the air. Except for the moment of pushing and contracting, basically no friction occurs, so that the hairspring returns the power directly to the balance wheel.

     Elastic balance springs are the heart of a constant dynamic escapement system, vibrating at a frequency of 3 Hz (21,600 times per hour); however, GP Girard-Perregaux watches have conducted other studies on vibration frequencies, but the purpose is not to simply challenge higher speed swing frequencies.

     The two escapement wheels are quite different from the escapement wheels of the lever escapement system. The escapement wheel with a frequency of 3 Hz has three teeth and the escapement wheel with a frequency of 4 Hz has four teeth. The movement has multiple days of power and the dial has The linear power reserve display can show the efficiency of the escapement system for a long time; the movement power is provided by two parallel barrels, which includes a new patented design: the barrel cover and the pawl are integrally formed to make the best use of it. Movement space; each winding drum has two winding springs; in addition, Girard-Perregaux has applied for registration of two patents, including the hairspring technology published in 2008, and the other one for the first time in the flexible system ) With limit stops.

     Although the balance spring and escape wheel are most ideally made of silicon, the final escapement wheel is made of other materials; the main body of the brass movement is treated with black PVD coating to add a sense of time; the modified structure of the movement has both a three-dimensional effect and See the excellent tradition of Girard Perregaux, for example, near the dial, the brand’s classic three bridge plywood is arranged in a new layout, and the back of the movement has two arrow-shaped plywood.

     Girard-Perregaux designed this escapement to take into account future maintenance factors. The entire escapement structure is a module that can be handled by a designated watchmaker.

     The first constant-power escapement

     The case design with the revolutionary constant-power escapement is ingenious and perfectly demonstrates the value of this innovative technology.

     Girard Perregaux Haute Horlogerie The first constant-power escapement watch, combining cutting-edge technological achievements and time-honored design, and strictly adhere to the brand’s traditional design style; white gold case diameter 48 mm, curved ring Beautiful.

     The dial layout emphasizes the structure of the butterfly wing frame of the constant power escapement system and the structure of the elastic hairspring. The hour dial is moved to the 12 o’clock position, with two spring drums on the left and right, and a linear power reserve display at 9 o’clock.

     Below the dial is the stage where the constant-power escapement is unveiled, swinging at a frequency of 21,600 times (3 Hz) per hour, and the new arrangement of Girard-Perregaux classic three bridge splints can be seen through anti-glare crystal glass.

     The thickness of the manual-winding movement is less than 8 mm, the case thickness is 14.63 mm, and the crystal glass back is set with 6 screws. You can see the three-dimensional movement structure and decorative beauty. It is equipped with a hand-stitched crocodile leather watch. Belts and discounts; belonging to Haute Horlogerie.

    Celebrity Charity Night Everyone Cares About The ‘c’ Battle. Actually, The Competition On Their Wrists Is Just As Fierce.

    The annual Bazaar ‘Star Charity Night’, although charity is the eternal theme of the event, but the scene where big coffee stars gather can indeed cause topics and controversy by accident As soon as the party ended, the subtle relationship between female stars and the C position of the photo group became a hot search. Although it seems that these disputes have little to do with male stars, they actually have secret contests in other areas, and the most prominent ‘competition field’ is on the wrist.

    Deng Chao attended the event

    Deng Chao wears Patek Philippe sports series

       Unlike female celebrities, male celebrities do not have a Care position, and their relationships are not so sensitive and complicated, but watch taste is where they will compete on the red carpet. In this regard, Deng Chao showed no twists. Not only the red suit was eye-catching, but the Patek Philippe ‘Nautilus’ on his hand was also generously exposed. Of course, Pose also had to take care of the photographer and take more shots

    Jiang Jinfu Decatur Key Series Skeleton Automatic Watch

       Even if he cut an inch of a domineering man, Jiang Jinfu still looked like a good boy. Clean white suits and black trousers are the most standard standard on the red carpet. Of course, the choice on the watch must take a different approach. Cartier key series skeleton automatic watch, Cartier’s iconic Roman numerals are transformed into movement skeleton bridges, III, VI, IX, and XII digital skeleton bridges and movements contrast with each other between reality and reality, and the inside and out are cleverly revealed.

    Hu Bing wears Chopard LUC watches

       Hu Bing, who has a very temperament, picked a dovetail dress for the red carpet. The clothes are elegant and gentleman-like, while the watches are responsible for highlighting the precision and elegance of men. The Chopard L.U.C Time Traveler One is the first world time watch of the brand’s L.U.C series, which is specially created for travelers around the world. This practical complication watch makes it easy for the wearer to read the time in various time zones around the world. In the gentleman’s manner, unknowingness reflects the wisdom of men.

    Zhang Yixing Dai Shangmei Paris “Bee Butterfly Opera” series watch

       Shangmei Paris watches are generally worn more by female stars. Zhang Yixing chose to wear it, which is really a little ‘courageous’. Because this ‘Bee Butterfly Drama’ watch, the dial is decorated with colorful butterflies, bees and flowers, which is very feminine, and most men will avoid it. Zhang Yixing also suppressed the watch’s tenderness in a black suit. It is also because of the contrast between the two extreme styles that his style becomes more special.

    Yang Shuo Dai Baozheng Marine Watch

      ‘Small bag total’ Yang Shuo always squeezes out an iconic dimple every time he takes a picture. Look at the “big gold watch” on the wrist that was deliberately pinched through the cuffs. The diameter of the 45 mm dial is difficult to keep a low profile. Yang Shuo’s watch with a strong sense of presence is from the Breguet marine series. The case decorated with Breguet’s classic coin pattern looks tough and overbearing. If you change to other men’s wear, you may have to think about it. Yang Shuo, who has a ‘flattering to the end’, dare to take it concave.

    Gao Yunxiang Dai Piaget Altiplano 60th Anniversary Series

       Actor Gao Yunxiang’s wave point dress is well-formed, and the Piaget Altiplano 60th Anniversary watch on the wrist is more textured and distinctive than clothing. He also quite ‘smartly’ adorned the watch with silver bracelets. In fact, for men, stacking is a bit of a snake, and a watch can highlight the aura.
       Most female celebrities will choose more feminine jewellery accessories as a wrist accessory on such occasions, and few female celebrities wear watches. However, Zhang Ziyi, Qin Hailu and Zhang Liangying opted for diamond-set watches in the opposite way.

    Zhang Ziyi wears a Bulgari SERPENTI watch

    Qin Hailu Dai Tiffany Cocktail Series

    Zhang Jingying Di Cartier Baignoire watch

       Zhang Ziyi’s neon-colored dress with a Bulgari SERPENTI watch has a feeling of heavy makeup and light touch. Qin Hailu, who wore a sparkling sequin dress, although the selected Tiffany and her charm and experience are not quite equal, fortunately, the diamond decoration on the square watch can always fill these vacancies. Zhang Liangying, who is relatively low-key, wears a yellow dress and only uses Cartier Baignoire watches to add a bit of grandness, bright and not glamorous, and worthy of praise.
       Compared to the celebrity female celebrity battle that depends solely on speculation and brain supplement, it is better to look at their watch contests, seemingly more real.

Let’s enjoy the Piaget Limelight Stella series white gold diamond watch, the official model: G0A40111.

       Limelight Stella is Piaget’s first complication watch exclusively for women. It was independently designed and developed by La Côte-aux-Fées (Fairy Slope) and Geneva Watchmaking Workshop, and continues to write a new chapter in Piaget’s love with women. Since ancient times, global culture has compared the bright moon to the eternal and gentle feminine glory. Piaget interprets this classic image with brand new thinking, and casts the beauty of moonlight like a poem on the dial forever. The years of flowing gold are filled with dreams and imaginations, imprinted in the heart.

       The moon’s gloom and clearness are always imaginative. Under its bright appearance, hidden secrets are hidden … the presence of the moon is always a surprise. Her faint figure still wandered the sky after sunrise until sunset. Regardless of the profit or loss, the clear luster of the moon makes people stare again and again, but it is always unpredictable and difficult to figure out.

       The central seconds dial and the moon phase display at 12 o’clock position each other in pairs; a large star hand on the large second hand shines brightly, adding a subtle beauty to the sun-moon alternation on the wrist. The intricate and delicate mechanical design of the movement perfectly interprets the cycle of the bright moon from profit to loss. The large moon phase display at 12 o’clock positions a piece of sky for the wrist of the fiber, and in the eternal chasing cycle of the sun and the moon, let A glimpse of the mysterious beauty of the moon suddenly looming. The moon phase display function has been adjusted for 122 years.

       Piaget presents a new self-winding mechanical movement independently designed, developed and produced for Limelight Stella. Equipped with a 42-hour power reserve, the Calibre 584P movement drives the hour, minute, second and moon phase display functions of the watch. The 584P and 580P movements, with a thickness of 11.5 centimeters and a diameter of 26 mm, vibrate 21,600 times (3 Hz) per hour like traditional models.

    As the first watchmaking brand that mass-produces automatic movements on the outer edge, Bucherer lays a pioneering position in technology. The oscillating weight rotates along the periphery of the movement, and does not cover the movement like a traditional center-mounted oscillating weight. At the Baselworld Watch & Jewellery Expo 2018, the brand first applied the self-made CFB A2050 movement released in 2016 to the new Maliron series watches, blending with the series’ traditional design aesthetics, integrating top technology, traditional watchmaking technology and Elegant appearance in one, leaving a deep impression. It is worth noting that in addition to the existing 40.6 mm style, the new timepiece is updated with 6 43 mm styles, of which 2 rose gold models are equipped with crocodile leather straps, and 4 stainless steel models can be equipped with belts or steel chain straps. , More matching options. Let’s take a look at the black dial stainless steel as an example: (watch model: 00.10921.08.33.01)

       Although the size of the new watch is slightly increased, it still does not damage its timeless temperament, and it is still elegant and round; the sharp outline, soft line arc, and polished matte finish make the watch’s elegant style even more outstanding.

       The 43 mm case is more generous in size, but the proportion of the watch’s right line is consistent; after polishing and refinishing, it is fuller and more refined, showing a smooth line beauty.

       The exquisite stainless steel crown is located on one side of the watch. The Bucherer logo is engraved on it, and it is decorated with a non-slip texture. It has a first-class feel and is easy to debug.

       The dial layout is adjusted with the increase of the case. The wedge-shaped hour-markers and pointed sword-shaped hands slightly increase, while the color of the hands and time-markers is the same as the case. The 6-hour mark position is a small seconds dial, and the 3-fold mark position is provided with a calendar display window, which adds practical functions to the watch.

       The self-made CFB A2050 movement is stored on the chain by Bao Qicai’s patented bi-directional outer rotor. The outer rotor does not block the movement.

    Star Trek With The Little Prince Pilot’s Watch Chronograph ‘little Prince’ Special Edition

    Schaffhausen, May 19, 2015-IWC Schaffhausen launches a new pilot chronograph watch ‘Little Prince’ special edition, with its originality The astrolabe week shows you as you embark on an interstellar journey with the little prince. The inner circle of the dial is arranged around seven planets, and a golden light blooms every day, symbolizing that the famous little prince described by Anthony Saint Exupery visited a new planet on his interstellar journey. The back of the watch is also engraved with the seven planets and is marked with the names of the inhabitants of each planet where the little prince stays.
       A king who wants to rule a territory that doesn’t exist; a businessman who thinks he owns the entire universe; a geographer who never leaves his writing desk—from his little planet to find friends The little prince, on his journey, encountered a variety of strange characters from other planets. This interstellar journey described in Anthony Saint Exupery’s most successful literary work, The Little Prince, became the source of inspiration for IWC. Inspired by it, IWC has carefully crafted a new Pilot’s Watch Chronograph ‘Little Prince’ special model (model: IW371807) with charming mechanical functions. ‘The collaboration with the Anthony Saint-Exupery Youth Foundation provides inspiration for several of our special edition pilot watches,’ said Georges Kern, chief executive of IWC. ‘Since the book’ Little Prince ‘celebrated its 70th anniversary two years ago, we have introduced many different models to pay tribute to the young heroes in the story. The special edition not only has an exquisite needle-tracking device, but also a childlike star-like element. Maybe it doesn’t look strange at first glance, but it is very subtle.
    Light up magical stars every day
       On the night blue dial with a unique cockpit design, a surprising planet-jumping dial runs as a week displayed in a thin line ring in the center of the dial. On this glamorous week display, a different glittering golden star is lit every day. However, the days of the week do not change in a particular order, and the flashing Venus looks as if it is jumping randomly at seven different positions on the dial. The hollow planet on the dial symbolizes the planet the little prince once visited. The names of these planets and the people who inhabit them are engraved on the bottom of the watch in the same order on the dial: the king, the vanity admirer, the alcoholic, the merchant, the lighter, the geographer, and the rose that the little prince will remember -After ending his adventure, the little prince returned to Rose. At the bottom of the table, it can be a fun experience to trace the planet this little boy with wheat-colored blonde hair is visiting. The center of the case is also decorated with a portrait of the little prince. The wearer can make the golden stars jump to another position by turning the crown. In other words, which star on the dial blinks on seven days of the week is entirely up to the wearer.
    The chase time starts!
       The complication of the chronograph hand also now has a place in the ‘Little Prince’ special edition series of the pilot watch series. Chase chronograph, also known as rattrapante, is a watchmaking challenge that is often underestimated. With two superimposed chronograph seconds hands, the wearer can accurately record split times in as little as one minute. The fascination of the special edition of the pilot’s chase chronograph ‘Little Prince’ is that it not only has all the technical characteristics of the pilot’s watch, but also has a poetic design element. The powerful features of this watch include self-winding, time, date, star-shaped week display with jumping, small second hand with stop device, 12-hour cumulative chronograph function, hand tracking function, and stable assembly to withstand sudden steps The pressure-reduced double-sided anti-reflective sapphire glass mirror also includes the strong antimagnetic protection provided by the soft iron inner case of the IWC pilot watch. The night blue dial reflects the elegant sportsmanship of this watch. The hands and scales are treated with Super-LumiNova® *, which ensures clear reading even at night. The lettering on the bottom of the table clearly indicates that the watch is limited to 1000 pieces. The Pilot’s Chronograph Chronograph “Little Prince” comes with a brown matte calfskin strap with beige stitching.
