The RICHARD LANGE TOURBILLON “Pour le Mérite” and its historic predecessor.

The hours dial segment is advanced clockwise by 90 degrees every six hours.

Generous openings in the three-quarter plate reveal afford in-depth views of the fusée-and-chain transmission.

Glashütte, January 2011

The fourth A. Lange & Söhne timepiece honoured with the distinction “Pour le Mérite” embodies a fusée-and-chain transmission as well as a tourbillon with a patented stopseconds mechanism. The underlying purpose shared by both of these grand complications is to improve rate stability and precision. The prominent regulator dial with its fascinating pivoting segment was inspired by a famous historic paragon.
