  1. Hello, my dear friends. :P :D I share this thread with you and hope you will be benefit from the following suggestions before you are gonna buy a pre-owned AP. You had better to keep these suggestions in mind, they will help you greatly when you are decided to buy a pre-owned AP, especially a Royal Oak or a Royal Oak Offshore. 1. If you got a vintage AP and you do not know its service history, you had better not to send it to the AP service center unless it stops running. More importantly, you should not take your vintage AP to any other independent watch shops to check or repair your watch. Although you can save your money at those independent watch shops, but I strongly believe that you will feel regret about that and pay the money you have saved someday. 2. If you wanna buy a pre-owned modern AP Royal Oak or Royal Oak Offshore, you had better to get the one that looks not so old (F series or pre-F series) but with service history and has overall great shape, this kind is and ideal choice. 3. If you got a 5402, you should know that this watch is equipped with cal. 2121 and be careful with its crown and avoid using quick-set calendar advance function. (While the watch has no a date setting crown, you can just move the hand to pass the midnight’s position and stay in the position of 1 am or 2 am, and then move the hand back to the position of 10 pm to adjust the day quickly, hence you do not need to adjust the date by going through 24 hours.) In fact, I had gotten four 5402 watches and their crowns indeed had problems, such as the crown stem was broken or the crown was pulled out when I tried to have a date set. What’s more, one of them was broken twice during two-year period. When you wanna pull the crown out, you had better to be careful and pull it slowly. Furthermore, when you have a winding, you should not turn more than 5-7 turns of the crown. 4. If your 5402 has been serviced, you still need to prevent your watch from being wet while you wash your hands, because AP does not guarantee any water resistance of your repaired watch. 5. If you wanna buy a ROO (pre-F series), you have to make sure that it comes with service paper or service history. If it does not have these conditions, you had better to give it up, unless you know the owner or this watch is indeed flawless. 6. Never take your watch to the independent shops to have a polish on the bezel or other parts. If your watch has been polished those shops, it would lose the AP bevels and the bezel will become rounded and thinner over time. AP used special machines to keep the intact octagonal shape and make the polished/brushed areas perfectly balanced. 7. If you own an AP and it is still within the warranty period, you have to make sure that the warranty has been registered, and then get a third year sticker. If the warranty of your watch is about to expire, you can send your watch to AP after service center, after all the procedures have been finished, you can get another 2 years warranty. 8. If you open a case back of a RO, you should not attempt to open its anti-magnetic casing which keeps the movement inside, because those screws are delicate. Furthermore, if you open the case back, AP will surely know that you have opened the case and they would refuse to provide any after-sales service. 9. If you wanna go to AP after-sales center, you should do research firstly, and then take your watch along and prepare enough money. The services of modern AP watches are expensive, but not as expensive as the vintage watches, unless your modern watch is seriously broken or your movement had been messed up by other watchmakers. 10. You had better not to choose a RO quartz, because its battery needs to be changed every 2-3 years. Change of battery needs the disassembly of the whole watch. Bezel, dial, hands, crown and so on are needed to be removed, and then the movement is accessed and the battery is replaced. If you take your watch to independent watch shop to change the battery, the process is so tedious that the watchmaker would do something wrong. Eventually, you have no other choice but to take your watch to AP after-sales center which charges high fee, and they will probably force you to do a periodic service. Okay, that’s all. I hope this thread would help all of you a lot. Thanks for reading.
  2. 1892 The first minute repeater wristwatch was produced. 1899 A "Grande Complication" pocket-watch published by the AUDEMARS PIGUET.

  3. Look around the whole watch world, Audemars Piguet undoubtly enjoys a high reputatuion by virtue of its precise skills and innovative capability. Many watch lovers are obessesed with Audemars Piguet complications, but if we talk about the model that is the best well-known and popular in all of the Audemars Piguet watches, the octagonal Royal Oak may be the most eye-catching one. The price of Royal Oak is also affordable. In addition, there is an interesting romaunt hiding behind the characteristic look of Royal Oak that had ever been an epochal pioneering work. Royal Oak First, you may know nothing about that the famous work Royal Oak was actually created by Gerald Genta, a genius in watchmaking industry. Gerald Genta was an Italian who was born in Geneva, he had created numerous famous and salable watches for other watch manufacturers before he started his own business. So far, besides Audemars Piguet Royal Oak, many of these Gerald Genta's creations are still the hottest types in their brands, including IWC Ingenieur, Patek Philippe Nautilus, Omega Titanium and Bvlgrai series. Royal Oak launched in 1972. 1950 seems smaller on the side of Offshore T3. Next, Audemars Piguet led a fashion on wrist-watch design after the release of Royal Oak in 1972. First, the characteristic octagonal case plus the revolutionary design of exposed screws have broke an unwritten rule that had existed for decades in field: all of components should be hided, since then, Royal Oak influenced the watch design around the world and became the eternal treasure in this field, it is still one of the masterpieces of AP untill today. Second, Royal Oak is the first watch made from stainless steel among top-level watch factories, it had astonished the field in those days by the unprecedented 3300 swiss franc, and had been the precedent of high-class wrist watch that marched to sports watch field. The octagonal case of Royal Oak fixed by screws featured a round bezel, such solid look settled the model of sports watch at a stroke. Third, the big dial design of Royal Oak (36mm, on the basis of the standars in those days), IWC Portugieser and the later Panerai Luminor were called the three big watches that leads the trend. Royal Oak Chronograph City of Sails The praiseworthy thing is that Royal Oak has kept the innovative idea since it was launched, its speciality of fully innovative was inherited from the fine tradition of AP, that is devoting to the tradition of making perfect products and pursuing endless curiousity from begining to end. Since 1972, Royal Oak had set up its own particular image and achieved that absorbing fans by its design, showing the philosophy of time through its own way. Though it was equipped a complicated movement, it still has exquisite lines, the almost perfect geometrical lines has been the soul of Royal Oak, and the octagonal case has been the symbol of this ledgendary watch, became a unique trademark. Besides the first Royal Oak which was initially made from stainless steel that was ignored by the luxurious field, AP also manufactured a flawless and characteristic case that let the stainless steel seem as exquisite as the luxurious metal. H.M.S. Battleship Royal Oak Jumbo Openwork Royal Oak is originally a warship of British Royal Navy that was started using in 1830, it was loading the most varieties and maximum amount of weapons in those days, and the designers of Audemars Piguet gained the inspiration from this Royal Oak warship. The octagonal porthole was the origin of the unique octagonal case, because the porthole was symbolized power and water-resistance. The reason why does oak take such an important position in British was that once King Charles the II England eluded the enermies' chasing and attacking in the puritan revolution period in 15th century, he hided in an oak which finally saved his live. Therefore, King Charles the II appointed the oak as the symbol of Royal protector, since then, oaks take a homage position in the British Royals' hearts. Royal Oak 30th Anniversary Nick Faldo Royal Oak Nick Faldo After the first cooperation between Royal Oak and the ledgendary golfer Nick Faldo who had ever been the champion of American Classic and British Open, Audemars Piguet expressly invited Nick Faldo to be its ambassador and signed a contact with him in 1989. In 1990, Nick Faldo won The Master and British Open, became the most popular celebrity in golf field. AP was more convinced Nick's achievements after his second time won the British Open, so it designed Royal Oak Nick Faldo, an memerable wrist watch that was made from a rare metal tantalum for him, to show that Nick Faldo's achievements in golf field suit the faith of AP that insisting to produce fine quality. The worldwide 450 limited edition Royal Oak Nick Faldo were being the major symbol of the Royal Oak 30th anniversary. Royal Oak Foundation Audemars Piguet Foundation In 1992, in order to celebrate the 20th anniversary of Royal Oak, Audemars Piguet particularly established a foundation to save forests in the world. AP commissioned the two outstanding organizations in forests protecting actions - IUCN located in Switzerland and US Arm of Great Britain's National Trust to supervise the operation of the foundation. So far, the foundation has gradually carried out forests conservation research project in many countries, including French, Spain, Malaysia, Switzerland, Northern Ireland, America, Pakistan, Costa Rica and Britain. Of course, for the sake of commemorating and showing the aim and operation of the foundation, AP had launched Royal Oak Foundation. Royal Oak Offshore Chronograph Royal Oak Offshore In 1993, Audemars Piguet launched Royal Oak Offshore. Bigger and more tough case with up to 100m water-resistance, which built a more advanced image of Royal Oak sports watch. Royal Oak Offshore was not only intensified the look of its sports watch, but seriously followed the high-class and rigorous watch making progress. Taking the case of Royal Oak Offshore as an example, it has to pass over 250 steps processed, including manual procedures like bevelling, polishing, brushing, sandlasting and circular-gaining, etc. The 30th anniversary of the legendary Royal Oak: Concept Royal Oak Concept Royal Oak 30 years past, Royal Oak did not lose its bold and innovative spirit and kept the status as a model of sports watch. It insists to offer excellent watch performance and follow three main beliefs of AP: traditional, excellent and creative. Royal Oak Concept is the special trans-century elaborations for elebrating the 30th anniversary of Audemars Piguet. Royal Oak Concept is a watch devoted to innovate and symbolized a brand-new aethetics way that developed from origin, purpose to set up the new century style of the new generation of Royal Oak. Therefore, the design of Royal Oak Concept was definitely a futuristic, its materials chose from the newest technique, its manual winding movement has also made a great progress in elegance and complex. Concept Royal Oak At 12 o'clock of Royal Oak Concept, there is a dynamographe(feature 1) that was launched by Audemars Piguet in 2000. Dynamographe can display the precision of a watch through the consecutive torque comes from the mainspring, provided that dynamographe hands stayed in the definitive position, means the power of the spring can offer the movement the best accuracy, however, if the dynamographe hands diverged, that means the watch need to be wound. At 3 o'clock, there is a special linear power-reserve indicator (feature 2). Linear power-reserve indicator was produced by Audemars Piguet in 1885, Royal Oak revived this creation and marked the power-reserve status with linear digits, every unit index stands for 6 hours power-reserve ability, 12 means 72 hours power-reserve ability. 9 o'clock is a shock-absorbing tourbillon (feature 3), more special is that this tourbillon was fixed by two big shock-absorbing spring at its two ends that can absorb shock even though under a serious circumstance, improved the accuracy of tourbillon and chronometer. In addition, Royal Oak Concept was equipped an R-N-H function selection indicator (feature 4) over at 6 o'clock, press the function selector button at 4 o'clock before adjusting time or winding, only adjusted it to a right function that can carry out the next action you want, avoided unnecessary mistake operation and abrasion. Royal Oak Concept Royal Oak Concept was specially designed for athletes, worn under a serious circumstance. Hence, its outside-to-inside adopted the newest surprisingly material that was usually used for aviation, medical science and energy production. Its case was made from the alacrite 602, a cobalt-based alloy that was originally used for aviation. Alacrite 602 is an extremely tough super alloy, made of 57% cobalt, 31% chromium, 5% tungsten, few carbon, silicon and iron that used in aerospace industry, twice more rigid than steel, and this is the first time used in making watch. The bezel, buckle and movement of Royal Oak Concept was made from titanium, light and anti-corrosive. The crystal and see-through case back adopted sapphire crystal, it used a rubber strap than can suit the most serious circumstance. Caliber 2896 Royal Oak Chronograph Limited Edition NYC Boutique Notes: Royal Oak Offshore Chronograph Terminator 3 After launching the limited edition by the first cooperation in End of Days in 1999, AP cooperated with Arnold Schwarzenegger once more in 2003, created a brand-new Royal Oak Offshore Chronograph T3 that was worn in Terminator 3: Rise of the Machines. This T3 is the biggest type of Royal Oak Offshore, only 1000 pieces in the world. T3 fully revealed an unprecedented vigour in size, 57.2mm wide(including crown guards), 32.5mm in dial diameter. It adopted a big grid-like dial, which contains two colors - grey and silver. Tritium-coated Arabic hour markers, the watch is the largest model in Royal Oak Offshore that gave it an excellent readability, especially at night. Besides wearing on wrists, the most fashion way is to wear over sleeves! Arnold Schwarzenegger and T3 Besides the outstanding big size, the crown design of T3 also has its own chracteristic, the special protections designed to protect the crown and push-pieces from shocks, the peculiar structure of Offshore ensured 100m water resistance. Moreover, its super size will not bring it a heavyweight, cause it adopted the extremely light material titanium that possesses high hardness, anti-corrositive and anti-allergic performances. Royal Oak Offshore Chronograph T3 Though it was launched over 30 years and has taken a bit changes in models looks or in their performance design, the Royal Oak still followed the creative conception of initial octagonal porthole and modified the original design, produced a more special type. Hence, Royal Oak is still the most perfect trans-century design watch and one of the most classical watch in those days after 30 years, sustaining attracting fans' eyes. Royal Oak Annual Calendar Royal Oak wrist watch possessed diversified choices after 30 years development : men and women watch, automatic watch, date display watch, calendar watch, perpetual calendar watch, openworked watch, chronograph watch, super complicate watch; adopted materials mainly including platinum, gold, white gold, rose gold, stainless steel and diamente, even adopted tantalum and titanium alloy that are the rare metal in space. Concept Royal Oak was even first adopted alacrite 602. These materials were changed into luxurious materials to suit Royal Oak determination of pursuing perfectness. Royal Oak Offshore Caoutchouc SERTI Royal Oak conquered the world with its unique charm that just like operating surpasses time. In passed 30 years, Royal Oak passed the tests of time and comfirmed its foresight keeps pace with the times companioned by numeral athletes and adventurers who love and respect nature. Also spend time with the phycisits, biologists and philosophers who consecutive exploring the universe. It possesses a self-evident ability, its fans covered men and women athletes, super stars, researchers and collectors all over the world. All of its fans will brust their indescribable gloss by wearing this small timing machine.
  4. There is no doubt that AUDEMARS PIGUET created a miracle of watch technology since the Tradition of Excellence collection launched.

The reference number is 26066PT.OO.D028CR.01,47mm in diameter. AP created the way of date display as a pioneer:Eccentric type sub-dial marked 1-31 in the red Arabic numerals date dial. Month and week arranged for the same normal axis. The index from 12 to 1 is leap year display window. This unique perpetual calendar is clear to read and simple to use. As long as flip the watch straps, the date can be regulated. The retractable finger design can reverse time and avoid affecting the continual operation of perpetual calendar, protect the movement for mistaken operation. The sub-dial is another innovation at 7 o’clock to AP: Independent sub-dial jumps a grip per second, which is a great achievement of micro mechanical technique to shrink the size to the wrist watch in this device. The genuine revolution of the fifth piece of AP Tradition of Excellence bring about the merits of non- lubrication, separated escapement, direct transmission, high efficiency, excellent shock-resistant and stable performance, precision, etc. Soul of the fifth movement Cal. 2899 – balance, balance spring —different as others, adopted design of two hairsprings which offset at 180° to each other provide a better balance and a better regulation. In case the spring out of balance, it can adjust itself to balance. In this regard, AP moved a step forward in the way to pursue the highest mechanical precision. The tradition of creation and development The function of the escapement is to maintain the wrist watch heart (balance-spring) in regular operation, is a major part of movement. So the watchmakers do their utmost to improve escapement. One of main objective is to reduce the operating energy loss to minimum. And maintain the optimum operation status when the system suffer from striking and move in position. Before Swiss lever escapement became to the global manufacturer mainstream, a lot of talented watchmaker made an attempt to invent escapements run by different principles, such as crown-wheel escapement, dead-beat escapement from Graham, detent escapement from Leroy, escapement from MUDGE and so on. In 1791,Robert robin who employed by the emperor(1742-1799)came up with a new invention, that is a combination of detent pawl escapement (high efficiency) and lever escapement (stable to operate). Owing to the fragile geometric construction, Robin’s invention was not use in widespread. The manufacturing progress is not only complicated but also harsh to the requirement of form precision. It is impossible to the technique in 18 century. The advantages of the innovated escapement system AP new escapement originated from the improved design of Robin. It maintained precise even suffered from strong striking. To solve the shock-resistant, AP watch maker designed a new type guard-pin, it can prevent the system from slipping in the operation. Compared to the traditional Swiss lever escapement, there are lots of advantages technical specifications to the originate escapement in AP watch manufacturer all around the world. 1. Lubrication free-AP exclusive escapement with unique geometric structure can reduce the trouble in applying oil to lubricate. It will simplify maintenance work and avoid blocking mechanical device after the lubrication evaporation. 2. Single impulse escapement- only one impulsion corresponds to two vibrations, so can reduce operation disturbance and improve efficiency. 3. direct impulsion-the power in escapement covert to balance directly instead of passing through lever pallets. So it will reduce energy loss. 4. High efficiency-traditional Swiss lever escapement consumed 70% energy itself. AP exclusive escapement only cost 50% energy. So the efficiency is higher than traditional movement. 5. Excellent shock-resistance-every shape of parts was designed elaborately, the precise cutting technique ensured the components will not shift by the strenuous vibration. 6. The optimum performance is stable-it is been verified that AP escapement is reliable after five years of long-term test.
