Additional Information
The case material used is 18kt "HONEY" colored gold, exclusively developed for Lange & Sohne. The honey gold has a subtle warm hue to it & has a color somewhere between white gold & yellow gold. With a Vickers hardness of over 300, this gold is about twice as hard as other gold alloys, making it more scratch resistant. "Fusee-and-chain transmission": In the Lange & Sohne fusee-and-chain mechanism, the flow of power between the mainspring barrel and the going train is established indirectly by a 636-part chain. One end of the chain is attached to the barrel drum and the other to the fusee. As the mainspring barrel unwinds, the chain wraps around it and reels off the fusee. When the mainspring is fully wound and thus exerts great force, the chain pulls at the smaller radius of the fusee where the leverage is smaller. As the springs tension diminishes, the chain pulls at the larger radius with the higher leverage. Thus, regardless of the state of wind of the mainspring, the same amount of torque is delivered to the escapement, resulting in improved rate accuracy. In the fusee-and-chain transmission mechanism, there is one situation when the cone rotates backwards: as the mainspring is being wound. To prevent the watch from stopping while it is being wound, Lange's master watchmakers integrated a marvel of miniaturization inside the fusee. It is a tiny planetary gear train that assures uninterrupted delivery of power to the movement. Additionally, it is endowed with a pretensioning mechanism that allows the characteristics of the mainspring and of the fusee to be perfectly harmonized. Finally, the elaborate construction includes a device that blocks the winding mechanism just before the mainspring is fully wound and stops the movement just before it is fully unwound. Overall, the fusee-and-chain transmission comprises more than 700 parts. 60 Seconds Tourbillon: The Tourbillon was developed to offset the disruptive effects of gravity on the balance wheel. It consists of a cage containing the balance, the pallet lever and the escape wheel. The balance & escapement rotate around their common axis going through all positions once a minute to average out the errors & thus resulting in a more accurate & consistent timekeeping. The construction of the Tourbillon mechanism in the Tourbograph is a true work of art, it consists of 84 parts yet weighs a mere 0.5 grams. There are only very few companies in the world that possess the technology and the know-how to produce balance springs, The Lange & Sohne factory in Glashutte is one of them. The production of top-quality balance springs is one of the most complex processes known in horology. It imposes extremely strict requirements on precision, both in the mechanical shaping operations and in the thermal treatment phases. One example: springs must be rolled to an accuracy of 100 nanometers. This corresponds roughly to one-hundredth of the diameter of a human hair.

A. Lange & Söhne was first established in 1845 by Adolph Lange in Glasshutte. The firm established itself as makers of distinctive and fine timepieces - its pocket watches were prized by European gentry. Following the Second World War, the Lange factory was seized by what was then East Germany. Walter Lange, the company's heir fled. It was only after the German reunification in 1990, that the founder's great grandson, Walter Lange, began reviving the company. With funding from LMH, the newly reformed company set out to restore its fine watchmaking tradition. The company was sold to the luxury conglomerate Richemont in July 2000. Although its watch parts may be cut with exceptional precision by the most advanced computer-aided machine tools, they are still finished, decorated and engraved by the skilled hands of some of the world's finest watchmakers.

In 1994, Lange debuted what is perhaps its most iconic watch, the Lange 1 together with the Saxonia, Arkade and Tourbillon Pour le Merite series. The Lange 1 features an off-center hour and minutes dial, a sub-seconds dial and a large date. In 1997, Lange Uhren GmbH presents the Langematik to the world, impressing the watch cognoscenti. 1999 brings the Datograph to Lange's growing adherents. It sets new standards in watch finishing and timekeeping. In 2007, A Lange & Sohne presents the Lange 31, a watch featuring a 31-day power reserve with constant power output.
