the first of its kind in the Audemars Piguet to go one step further

Bold and innovative design concept watch Royal Oak debut in 2002 , the legendary Audemars Piguet Royal Oak watches available octagonal 30th anniversary tribute. Royal Oak watch handedly designed by Gérald Genta, is the world's first steel crafted by the senior watch. This concept watch with extremely hard Alacrite 602 super- alloy case , highlighting Genta original octagonal bezel and eight hexagonal screws. Hollow dial demonstrate inbuilt advanced micro-mechanical devices. The revolutionary design of the whole concept watch series marks have been preserved in both , introduced from 2008 , for the first time combine forged carbon case and carbon board ultralight watch Royal Oak Carbon Concept Tourbillon Chronograph , to 2011 launch , with ultra-light and ultra-resistant titanium case , black ceramic concepts and Royal Oak octagonal bezel , buttons and crown GMT tourbillon .

       Unlike earlier black design, the concept of this year's Royal Oak Tourbillon GMT configure white ceramic bezel, crown and buttons , and titanium case in stark contrast. Today, the first of its kind in the Audemars Piguet to go one step further , with the movement of the ceramic one, to replace the 2913 movement in white ceramic black deck . Therefore , the new 2930 movement there are changes in the visual , its attention hourglass deck , with symmetrical Tourbillon GMT monitor deck and embraced , further showing the movement characteristics.

Material trick

        White ceramic hardness of about 9 times higher than the steel , which means Royal Oak Concept Tourbillon GMT bezel , buttons and crown, as well as modeling complex on the deck , subject to complex and lengthy process before being made percent. Ceramic is kind of scratch-resistant composite material almost completely , leaving only a diamond can scratch the ceramic surface , therefore , asked to ceramic processing , you must use a special tool equipped with a diamond tip cutter cutting device. Due to extremely high wear resistance of the ceramic itself , so their rough surfaces and edges polished or matte polish is absolutely key daunting technical challenges. The concept is to produce a single Royal Oak Tourbillon GMT bezel will spend nearly eight hours , if the production of stainless steel bezel , time is only 45 minutes, which is actually an extraordinary technical crystalline watchmakers and engineers. Ceramic not look smooth and bright , and high degree of resistance to abrasion , Hua Shi both .

        Titanium case and sapphire bottom trim used is also very strong, and wear comfortable, light as steel , which is conducive to the production of large widths up to 44 mm watch . In addition, the bezel around the dial to light anodized aluminum crafted to strengthen and further underlines the deep-rooted love of his knowledge of high-tech metals and materials .

        Such a bold combination of ceramic and metal , but Audemars Piguet in the field of materials science and technology research and development continue to challenge the limits of the latest chapter , in fact , the watch factory inventive early as 40 years ago , the use of stainless steel to create the first ever senior watch.

Technical masterpiece

       Consistency of the case and movement , the concept of Audemars Piguet watches has always been a major feature . The ultra-modern "engine" with ultra-modern " chassis " a perfect match , its technical aesthetics and exposed micromechanical complement the full show which features.

        Unique concept of Royal Oak Tourbillon GMT worthy of watchmaking masterpiece on 2930 manual winding movement with a power reserve of 10 days to provide double-barrel , tourbillon and a second time zone " GMT " display. Its travel time function consists of 3 Hz ( 21,600 vibrations per hour ) escapement drive , this system within the framework of the tourbillon rotates once every 60 seconds to watch at any time, the vertical offset placement of the gravity of the subject affected.

       A total of 85 Tourbillon frame parts , but weighs only 0.45 grams . Even experienced watchmaker also takes nearly three days to assemble these 85 parts , installation process framework which will last for two days , and the entire tabulation process may take up to two weeks more . Audemars Piguet is by far one can master all the tedious details of this complex function of the few watch factory , the brand has more than 25 different Tourbillon movement . Each parts are chamfered by hand , polishing , assembly and adjustment.

       GMT time display can be read instantly makes the second time zone. This feature ( each click that corrected one hour ) through the button to adjust the 4 o'clock position . Based on a 12-hour second time zone display with two overlapping discs , reading between the time help . The first disc engraved figures every revolution of 12 hours . In its second disc just below one turn every 24 hours , and were divided into two color areas, white represents the day, the black of night , easy digital reading .

      Audemars Piguet 's proprietary parallel twin barrel system to ensure that the Royal Oak Concept Tourbillon GMT watch can run for up to 10 days , after which only need to manually re- chain , this table can produce about 237 hours of constant self- motivation, greatly enhance accuracy of travel time . Power movement in the 2930 two -barrel 10-day chain generated , sent to the gear train at the same time through a single connection between the pinion . In terms of power transmission , which uses two parallel relative to the general system of the 5th chain barrel is more stable. This device also reduces the pressure on traditional gear train , the barrel is used to counteract the friction torque variation , so watch more accurate, has more power to save and enhance reliability.

Audemars Piguet

        Royal Oak Concept GMT Tourbillon also has a wide range of display devices. Turn the crown to the 6 o'clock position on the dial pointer indicates the selected function . H, N and R of the three positions corresponding to the crown , respectively, to adjust the position of the time , the normal position and the position on the chain .
