A. Lange & Sohne Richard Lange Tourbillon “Pour le Merite” Watch

Only a couple of luxury brands offer watches with fusee and chain complications, equipped with a tiny hand-made chain in a watch helping to move power from the mainspring to the movement. The watch is inspired by a pocket watch created by 18th century Saxon horologist Johann Heinrich Seyffert.

The watch comes with a three sub-dial regulator style display, tourbillon and a stop seconds mechanism. Each of the sub-dials represents the dial for the hours, minutes, or seconds. The seconds dial is cut away offering a peak window on the delicate tourbillon and movement underneath it. A small section, which makes up the full hour dial on the right, can also be hidden to reveal the full view of the tourbillon. The portion of disk that has indicators for 8 - 10 o'clock is hidden from view at 12 o’clock, to come into view again in 6 o’clock.

A. Lange & Sohne was the first manufacture to build up a stop seconds mechanism for a tourbillon, a couple of years ago. That complication has been used on the Richard Lange Tourbillon Pour Le Merite watch.

The watch utilizes in-house made and designed Calibre L072.1 manually wound movement, offering a 36-hour power reserve. The movement is composed of 636 parts, only the chain consists of 285 parts. The watch is crafted in either platinum or 18-carat pink gold, and comes in 41.9mm diameter wide case. The hands on the dial are in gold, and the dial itself is solid silver. The watches are completed with brown or black crocodile straps.

Only the platinum version will be limited to only 100 pieces, each worth $233,600. Pieces crafted in pink gold will be priced at $193,600.

The technical director of A. Lange & Söhne is giving the demonstration of the movement's features during a live press conference in Glashutte, Germany on December 7, 2010.
