A. Lange & Söhne 1815 Tourbillon Handwerkskunst Limited Edition Pink Gold Version

A. Lange & Söhne, the prestigious luxury watch manufacture based in Saxony presents a special limited edition 1815 Tourbillon Handwerkskunst timepiece to celebrate the 200th birthday of Ferdinand Adolph Lange.

Introduced in 2014, the 1815 TOURBILLON is the first A. Lange & Söhne watch that combines a stop-seconds device for the tourbillon and the ZERO-RESET mechanism. At the close of the anniversary year that commemorates the 200th birthday of Ferdinand Adolph Lange, this high horology timepiece is being presented in a limited HANDWERKSKUNST edition featuring extraordinary dial and movement decorations.

Handwerkskunst is an attribute of distinction that A.Lange & Söhne has been using since 2011 to identify special limited-edition watches whose dials and movements are endowed with rare finissage and engraving techniques.

The 1815 TOURBILLON HANDWERKSKUNST not only stands out with exceptional decorative elements, but also unites two patented mechanisms. The ZERORESET function launched in 1997 by A. Lange & Söhne is paired with the stop-seconds device for the tourbillon that was introduced in 2008. Together, these mechanisms make it possible to stop and set the timepiece with one-second accuracy.

Limited to 30 watches, the special-edition model is available in a pink-gold case with a diameter of 39.5 millimetres. The dial is made of black rhodiumed pink gold and decorated with elegant tremblage engraving. The engraver who uses this technique sculpts the material with a specially crafted lining burin to achieve a uniform, fine granular structure.

The relief elements on the dial, including the prominent arced brand logo and the numerals, are later polished to a mirror gloss and contrast prominently against the dark background. An aperture in the dial reveals the large one minute tourbillon. The Tourbillon Bridge and the upper part of the cage are black-polished: this is one of the most elaborate and time-consuming finissage techniques.

Mechanical precision is reflected in every detail of the lavishly decorated Lange L102.1 manufacture calibre. The elegantly curved shape of the newly designed three-quarter plate is a special hallmark. Thanks to generous cut-outs, the tourbillon with the patented stop mechanism is easily visible from the movement side as well, as are the spring barrel and parts of the wheel train. The grained surface of the German silver plate is inspired by historic pocket watches.

Bevel-polishing re-entrant angles is a particular challenge. This task can only be performed manually with a sharp, specially designed tool. The fourth wheel bridge is pierced to provide a better view of the tourbillon. Just like the plate and the caseback, it is endowed with artistic engravings. The diamond end stone of the tourbillon vibrantly accentuates the movement decorations.
