With a fusée-and-chain transmission and a one-minute tourbillon, the L072.1 as found in the Richard Lange Tourbillon “Pour le Mérite” incorporates two of the most effective complications that increase rate accuracy. Its third complication is the patented stop-seconds mechanism. Thanks to this device, the tourbillon – and with it the entire movement – can be stopped and restarted to one-second accuracy.
Apertures in the three-quarter plate expose the fusée-and-chain transmission, which is so complex that it is rarely implemented in wristwatches. The owner can observe how the intricate 636-part chain unwinds from the mainspring barrel onto the fusée while the watch is being wound. The fusée-and-chain transmission is one of the most effective complications when it comes to increasing the rate accuracy of a mechanical watch. It is one of the tenets of physics that the power generated by a spring is high when it is fully tensioned and significantly weaker as it nears the fully unwound state. This can cause rate-accuracy fluctuations. The fusée-and-chain transmission works like an infinitely variable gearbox. It equalises the waning force of the gradually relaxing mainspring and makes sure that the movement always receives a constant amount of energy.

A. Lange & Söhne - 1815 "200th Anniversary F. A. Lange"
The new 1815 "200th Anniversary F. A. Lange" in a limited edition of 200 watches was created by A. Lange & Söhne to commemorate the anniversary of an eminent and charismatic founding father.
Each detail of the L051.1 manufacture calibre pays tribute to the great Saxon watchmaking pioneer. Apart from the three-quarter plate made of untreated German silver, key hallmarks include the hand-engraved balance cock, the classic screw balance, the whiplash spring, the gold chatons that secure the bearing jewels, and the thermally blued screws. The serial number engravings 1815 "200th Anniversary F. A. Lange", Page 2 on the case from 001/200 to 200/200 identify each watch as a proud exemplar of the anniversary edition.
The 40-millimetre platinum case and the black solid-silver dial emphasise the sleek elegance of this timepiece. With its three levels and the subsidiary seconds at six o'clock, the face is reminiscent of the legendary pocket watches crafted by Ferdinand Adolph Lange.
His objective, he wrote in 1843 to the Saxon government when he was 28, was "to imbue the watch itself with the great and important flawlessness and simplicity that originate from my considerations and diligence". In the letter, he expounded on his plan to produce pocket watches in Saxony. This vision began to materialise two years later in his newly established manufactory. The former mining town of Glashutte had become a hub of fine watchmaking.
But before Lange laid the foundation for the global fame of A. Lange & Söhne with trailblazing chronographs and pocket watches with jumping seconds, remontoirs and quarter repeaters, he initially focused on the simple pocket watch. With continual design improvements, he achieved a superb degree of precision and reliability that buoyed his fledgling business. One good example is the three-quarter plate which evolved over several stages until its final form was developed in 1864. It was responsible for the stability of Lange's movements and defined the style of Saxon watchmaking.
The latest-generation A. Lange & Söhne wristwatches are also endowed with this component, an element that can be admired through the sapphire-crystal caseback.
