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.
This is the only wristwatch with tourbillon known to us 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.
