![]() The new movement made possible a redesigned dial that is subtly different, but substantially better. Studying the dial layout of a chronograph is an exercise in details, but it reveals how proportions are crucial to beauty. 4401 inside that’s the first in-house calibre found in the Royal Oak Chronograph. Launched earlier this year, the new Royal Oak Chronograph retains the recognisable style of its predecessor and is seemingly alike, save for a crucial detail. The chronograph registers have been lightly revised, giving away its most important upgrade – the cal. 26239 is very much a different watch, and one that’s tangibly improved. Though it might seem barely changed at a glance, the Royal Oak Chronograph ref. Two years after the base-model Royal Oak got was revamped with a latest-generation, in-house movement, Audemars Piguet has quietly updated its chronograph counterpart. Technical specifications appear below the images, which you may click to enlarge.Facebook Linkedin Twitter Pinterest Weibo Mail Instagram The Millenary Carbon One Tourbillon Chronograph will be produced in a limited series of 120 watches. Due to its minimal elastic deformation, this carbon provides a highly stable base for the metal elements attached to it. This amorphous and chemically neutral composite material maintains its dimensions over a broad range of temperatures. ![]() It’s an isotropic material composed of carbon nanofibres injected at an extremely high pressure of 7500 N/cm2 and at a temperature of 2400☌ in order to achieve a material possessing mechanical, physical and chemical stability in all directions. ![]() Eloxed aluminium is used for the the bridges and carbon for the mainplate, but not ordinary carbon. ![]() It takes about 15 days to assemble a finished movement, three of which are devoted to the 80-piece tourbillon. Once the watchmaker is sure that it runs completely smoothly, he takes it apart and cleans the parts before final assembly and casing up. This stage requires ten days of adjustments. Each movement is first assembled on a trial basis in order to set it into motion. Twin barrels actually store enough energy to power the watch for 12 days, but a locking mechanism allows the watch to run only during the 10 days when the power delivery is most consistent. The openworked dial reveals caliber 2884, a completely proprietary movement equipped with a tourbillon, a chronograph, and a 10-day power reserve. The high-tech materials and manufacturing techniques result in a very light timepiece indeed: the Millenary Carbon One weights just 69.44 grams. The bezel, crown and pushers are in ceramics. The case middle and lugs are made all of a piece. The hardness of 626 Vickers can be compared with the 420 Vickers score for alacrite, another highly resistant material. This process results in a material composed of 76% carbon and 24% polyamide. The mold is then compressed at high temperature at pressures of over 300 kilos per square centimeter. Placed end to end, these filaments are equivalent to 22.7 meters of carbon wire and 102.2 km of carbon fibers. The wire, measuring one millimeter in diameter, is itself composed of several thousand 7-micron carbon fibers held together by a resin wire. The middle section of the case is created by placing a set of threaded carbon filaments inside a mold. The case is forged carbon, an ultra-light material developed by AP. Audemars Piguet’s new Millenary Carbon One is a technical wonder.
