This is the first time a watch A. Lange & Söhne has combined the second stop for the tourbillon mechanism and setting the time Zero-Reset. Through the interaction of these two patented systems, the new 1815 Tourbillon can be stopped at the nearest second for the last time even easier.

The Tourbillon 1815 is designed to provide maximum accuracy. Outstanding driving stability is guaranteed by its tourbillon 60 seconds. The accuracy of the time setting is provided by the interaction of two patented systems: when the crown is pulled, the balance within the tourbillon stops instantly, and hand seconds immediately returns to the zero position. The watch can then be easily set the time from a watch or a reference time signal.

Watches with a tourbillon have long not been accurately set because it was not possible to stop the vortex. In 2008, manufacturers A. Lange & Söhne provide a solution to this puzzle successfully curb the balance immediately inside the rotating tourbillon cage. Pulling the trigger ring of a complex lever mechanism that lowers a movable V-shaped spring on the rim of the balance. It instantly freezes the balance. The Tourbillon 1815 is also provided with this patented mechanism, which can be observed partially through an opening in the dial.

But this time, developer’s timepieces Lange went even further: they associated this stop mechanism mechanism Zero Reset, also patented. By pulling the crown, not only we stop the second hand, but it is instantly backed to the zero position. Thus, the minute hand can be positioned precisely on a line marking the minute, and the watch can be restarted in the second.

It is this faithful to the ideal pursued by Ferdinand A. Lange, whose birth year gave its name to the watch. Only the swirl, as can be seen through a cutout in the dial indicates the complexity of the watch. The dial diameter was increased to 13.2 millimeters, or about a millimeter higher than in previous developments Lange. The small seconds hand is driven by the shaft of the vortex. To ensure the best possible contrast with the dial light in color, it is blued steel. Just like the classic timer “railroad” style Arabic numerals reminiscent of old pocket watches A. Lange & Söhne.

The spiral and the rim of the balance has been made with the utmost care by Lange and are perfectly suited to one another. We find the same attention to detail in the finishing of the movement, hand-decorated. Against the pivot diamond tourbillon is the coronation. With a diameter of 39.5 millimeters, the case in pink gold or platinum gives the Lange manufacture caliber L102.1 a framework for harmonious proportions. Limited to 100 copies of the edition platinum version emphasizes the exclusive character of this exceptional timepiece. The first tourbillon watch A. Lange & Söhne with second stop and zero reset reflects concern that at the factory always question the technical solutions and perfect.
