The dial design of the RICHARD LANGE TOURBILLON “Pour le Mérite”
was inspired by precision chronometer No. 93 crafted by Johann Heinrich Seyffert, a gifted watchmaker who in the late 18th century established the fundamentals of precision timekeeping in Saxony. Alexander von Humboldt, a natural scientist, expressed particular appreciation for his work and relied on his timepieces to calculate the co-ordinates of his locations during his expeditions and perform many scientific measurements
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 was used mainly in marine chronometers. The lives of an entire ship’s crew sometimes depended upon these time-keeping instruments. For the first time ever, Lange’s master watchmakers integrated this mechanism in the tiny dimensions of a wristwatch. The technical data of the chain suggests how much dexterity this venture requires. It consists of 636 individual parts and has a cross-section measuring 0.6 by 0.3 millimetres."
