Because of its impressive technical features and its esthetical appeal this tourbillon chronometer is the most prestigious of all wristwatches produced by A. Lange & Söhne, representing the culmination of over 150 years experience in the production of high quality precision timepieces.
At the end of the 1990s this was the only wristwatch with tourbillon produced today utilizing power equalization with chain and fusee. The tourbillon cage weights less than half a gram and measures just 12.3 mm in diameter, comprising itself 76 components. The planetary transmission gear, compensating for the decreasing power of the mainspring, is built into a miniature cone and comprises 38 separate parts.
The tourbillon "Pour le Mérite" was produced in a limited edition of 150 pieces: 149 pieces in 18 K gold and 1 in stainless steel. Out of the 149 in 18 K gold, 106 were produced in yellow gold, 24 in pink gold and 19 in white gold. There was also a limited edition of 50 pieces in platinum.
