A. Lange & Sohne, of Glash��tte, Germany, has just announced a new rose gold version of the LANGE 31. The LANGE 31 was originally introduced two years ago, in a platinum case. Over the last 2 years, senior designer, Martin Schetter, has worked with his design team to create a new variation. Two years seems like a whole lot of time, just to create a new variation of a timepiece. It is, but, Lange imposes so many quality and design requirements when creating a timepiece, that it takes this long. The results are worth the wait, as this Saxon manufacture produces some of the most beautiful timepieces in the world. The LANGE 31 is the world's first mechanical watch to boast a power reserve of 31 days and a constant-force escapement that powers the going train with constant torque delivery. The enormous amount of energy needed to keep the watch running so long is transferred to the movement with a winding key and stored in a twin mainspring barrel. This guarantees that the balance receives an identical amount of energy every ten seconds, regardless of the state of wind of the springs.A movement with such a large power reserve requires a lot of space. The movement alone, has a diameter of 37.3 mm and 9.6 mm thick. The requisite case is quite large. In fact, this is the largest A. Lange & Sohne timepiece available. For reference, Lange watch cases are generally 38 to 42 mm wide and 9 to 14mm thick. The case on the LANGE 31 is 45.9 mm wide by 15.9 mm thick. It's big. Available November 2009. Retail is $114K.[Press Release PDF: LANGE 31 Rose Gold ]

Lange & Sohne Tourbograph Pour le M��riteSeptember 3rd, 2010adminLeave a commentGo to commentsZTE brand shortly after Lange, in 1994, unveiled a 1815? Lange Tourbillon Pour le M��rite Tourbillon watch, it is not only the world’s first chain drive system with sesame (fus��e-and-chain) of the watch, but a combination of Games to watch long-term potential to improve the accuracy of the two stunts, sets tourbillon and sesame seeds in a chain, superb tabulation process sensational quickly become eager collectors of rare watches Luo purchase. Lange watch factory within this unique tourbillon called Saxon Tourbillon, see Watch Factory proud of this unprecedented scene work.?Lange in Glash��tte in 1882 set up its production of Sesame chain pocket watch to astonish the Observatory, and now the antiques are rare and have collectors all over the world to astronomical figures in the auction bidding race to the treasure. The Lange published another more impressive Watch – 1 minute Lange sesame chain Tourbillon Chronograph double tracking pin is also the world’s only have one minute tourbillon (one minute tourbillon), sesame chain drive system and two seconds chronographs (rattrapante) code watch watch the performance, both to his death in 2001, the G��nter Bl��mlein tribute, Lange shows no one has the skills and achievements.Tourbograph Pour le Merite??Tourbograph Pour le Merite sesame chain drive system (pagoda round and sesame chain)The main winding mechanical watch with full force on the chain or nearly depleted two different situations will produce different degrees of torque. When the primary winding in the chain, the final stage of power will be weakened, leading to errors ratio. Sesame chain drive system tray and will be the mainspring of its tower between rounds to a slender, like a bicycle chain with a chain as the chain known as sesame connected to each other. When a user for rotating the crown when the watch on a chain, the pagoda in the tapered chain round the top of the sesame seeds will be rolled up, winding the clockwork box will be stretched. Then, winding through the power will be transmitted to the movement round the pagoda to bring lasting change of torque, and thus improve the ratio of power reserve watch the whole accuracy. In short, sesame chain operation is the use of Archimedes discovered fulcrum principle: When the mainspring is fully on the chain and fully operational, sesame chain will be smaller circle, that is, pull the lever round pagoda ; and when the mainspring power weakens, sesame chain will be in the tower round the circumference of part of a larger pull.?This exquisite device improved the accuracy rate of power reserve watch, but when the chain need to be re mainspring, the movement will in turn stop moving. Therefore, Lange’s pagoda is also equipped with a wheel within a planetary gear so that movement of the mainspring for the chain, can still continue to run, just the gear needed by the 38 component parts, and the entire Sesame chain part number more than 600, making such a complex device to a little sesame chain and watch, the look of today’s altar watch only Lange have such excellent technology.Lange Tourbograph Pour le M��rite by the L903.0 hand-winding movement with the other parts are up to 465, and through the mirror polished and modified for curved frame one minute tourbillon from 84 parts. Adhering to the Lange’s watchmaking tradition, is decorated with small silver frame work fine on both sides of the shaft is inlaid with a diamond of all system-side stone. In addition, Tourbograph Pour le M��rite inherited Datograph and Double Split Chronograph unique technology with a dual-column-wheel double-needle time performance of seconds to recover. While this performance and extraordinary watch is 41.2 mm with the casting form of the watch, and the magnificent beauty of movement fine sanding and carving, decorated entirely by hand. Tourbograph Pour le M��rite will only be limited production 101, including 51 platinum and 50 gold, but because of its complexity and difficulty of production, is expected to Lange will only supply 12 per year of production.
