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. As for the prices, do not be surprised, Platinum Edition price rumored to be 380,000 euros.Lange Tourbograph Pour le M��rite will only produce 101 limited edition, platinum edition first appeared

The talented watchmakers at A. Lange & Sohne created Large 31, the first mechanical wristwatch in the world with a 31 days power reserve and a patented constant-force escapement able to power the going train with constant torque delivery. Lange 31 transcends the notion of power reserve while keeping the same high Lange standards and providing highest quality rate stability and rate accuracy for an entire month.The Lange 31 has an unmatched autonomy that allows you to forget winding it from time to time. The watch shows the right time for 31 days even if you take it off, a special function emphasized by the solid-silver dial engraved with the inscription "Monats-Werk". On the right hand side of the solid-silver dial, an ample indicator displays the power reserve. The left hand side is balanced with a stylish patented outsize date. A closer look at the sapphire-crystal backside of Lange 31 discloses the key-winding mechanism, another precision element rarely found in watch*** that was specially designed and constructed to match Lange 31. This mechanism permits more precise winding transmission ratio than a crown. Consequently fewer revolutions are required and more energy saved. Between the winding mechanism and the case there are three seals protecting the watch against water with maximum 3 bar pressure. The key is introduced through an opening in the sapphire-crystal case-back and has an integrated torque limiter that prevents damages of the mainsprings. In the moment the mainspring is entirely wound, any attempt to turn the key releases the triangular toothing of the two wheels and stops the power flow. The Lange 31 features a powerful L034.1 calibre stored in a 37.3 mm diameter and 9.6 mm height space. The energy storage function is provided by two stacked spring barrels which incorporate the two mainsprings. These two mainsprings are five to ten times longer than the springs of regular mechanical wristwatches and their compound energy is more than 3 joules, as their total length is 3700 mm. A constant force escapement controls the power delivery. It has a pretensioned spiral spring that instantly retightens on the fly every ten seconds. In a controlled way, the next ten seconds the stored energy from the spring is sent to the going train while the torque output constantly powers the watch to function for a month.In addition to the innovative movement, the aesthetic enhances the value of this timepiece. The model in platinum has a solid silver and rhodi�� dial, as well as rhodiumed gold hands and platinum deployant buckle. The model in 18-carat pink gold has a solid-gold deployant buckle, the dial made of solid silver, argent�� and the hands are pink gold. Both models have hand-stitched crocodile strap. Traditional Lange elements such as three screwed gold chatons and the whiplash precision index adjuster on the balance cock are also present. All finishes are superbly done.
