UNOBSTRUCTED VIEW OF ALL DETAILS.

Even watch lovers who cannot tell the difference between the various Lange movements at first sight will immediately realise that the L072.1 is a most remarkable calibre: For the first time, Lange's master watchmakers decided to cut generous openings out of the traditional three-quarter plate in German silver. While this is fascinating for the observer, it renders the assembly process much more difficult and time-consuming for the watchmaker. This is because openings reduce the torsional stability of the plate, making it more challenging to fine-tune the 352 individual parts.

A MINIATURISED INFINITELY VARIABLE TRANSMISSION.

For the very first time, a Lange watch exposes the chain that unwinds from the barrel while the mainspring is being wound; just before the fully wound state, a tiny hook engages and blocks the movement. The movement is also stopped just before the fully unwound state. This assures that the spring is tensioned only within its optimal energy range. The RICHARD LANGE TOURBILLON "Pour le Mérite" has a power reserve of 36 hours. Like a crown jewel, a diamond endstone adorns the traditionally hand-engraved balance cock: it has always been a hallmark of the most precious Lange movements.
