The Lange Tourbillon 'Pour le Mérite' was made in a limited edition in 1996. Of the production, 150 examples were made in gold with 15 in pink, 15 in white and 120 in yellow.

It is one of the highest quality tourbillons to have been produced in the last 15 years. With the chain-fusee equalizing the power of the mainspring as well as the up and down indicator, the watch is a marvel of mechanics and design.
