A. Lange & Sohne 1815 Tourbillon Platinum with stop-seconds mechanism and zero-reset feature.
For the very first time, an A. Lange & Söhne timepiece unites the stop-seconds mechanism for the tourbillon with the ZERO-RESET function. The interaction between the two patented mechanisms makes it possible to stop and set the new 1815 TOURBILLON with one-second accuracy.
The 1815 TOURBILLON is designed for supreme precision. Unprecedented rate stability is assured by the one-minute tourbillon. The interaction between two patented mechanisms enables the watch to be set with great accuracy. When the crown is pulled, the balance inside the tourbillon cage stops instantaneously and the seconds hand jumps to the zero position. The watch can now conveniently be synchronised with a reference watch or a time signal.
More than 200 years ago, the invention of the tourbillon was the ingenious solution to a serious watchmaking problem. Because pocket watches were generally worn vertically, the influence of gravity on the balance often caused considerable rate deviations. To offset this unwanted effect, it was necessary to constantly change the orientation of the oscillation system. So the balance and the escapement were placed in a rotating cage, called tourbillon. This compensated position errors and increased rate accuracy. Since then, the tourbillon has lost none of its fascination. Its micromechanical complexity and artisanal finissage still symbolise engineering prowess and horological precision.
The hairspring and balance wheel are crafted in-house with extreme meticulousness and perfectly matched to one another. Precision also comes to the fore in the intricate finish of all movement parts and is crowned by the endstone of the tourbillon.
