|The Tourbillon “Pour le Mérite” was produced in limited editions of 150 pieces in
18K gold, 50 in platinum and 1 in stainless steel. Of the 50 platinum examples,
10 had a link bracelet. Of the 150 in 18K gold, 15 were produced in white gold
and 15 in pink gold. A unique example was made in stainless style for Pisa, Milan.
This tourbillon chronometer is without exception the most prestigious of all
wristwatches produced by A. Lange & Söhne. It represents the culmination of
over 150 years of experience in the production of high quality precision timepieces.
As far as we know, this and only one other model (Lange’s Pour Le Mérite
Tourbograph) is produced today utilizing power equalization with chain and
fusée. Only 12.3 mm. in diameter, the tourbillon itself comprises 76 components,
weighing less than half a gram. The planetary transmission gear, compensating
for the decreasing power of the mainspring, is built into a miniature cone, measuring
only 10 mm. in diameter at its base, yet it comprises 38 separate parts.
Besides these impressive technical features, the extraordinary esthetic appeal,
flawless execution, and superb craftsmanship stand on their own.
