A. Lange & Sohne has launched a limited edition version of its Lange Zeitwerk, the Handwerkskunst, said to be new level of watchmaking owing to its decorated case, dial and movement as well as its Glashütte lever escapement.
The Lange Zeitwerk Handwerkskunst has a black-rdodiumed white gold dial featuring elaborate tremblage engraving designed to produce a delicate and highly vivid granular texture.
The engravers are said to have been challenged by the curved Lange logo and the filigreed lettering of the power-reserve indicator while the time bridge is decorated with linear graining and its rhodium German silver contrasts with the dark dial.
The case is platinum and all are numbered with individual serial numbers that have been hand-engraved.
It also boasts a sapphire-crystal caseback through which its complex manufacture calibre L043.4 can be seen, including classic Saxony watchmaking features such as the three-quarter plate and screwed gold chatons.
The three-quarter plate is made of untreated German silver and is decorated with a granular surface and hand-engraved lettering. The balance and escape wheel cocks are also decorated with a special free-hand engraving while the upper side of the bridge for the constant-force escapement is embellished with black polish, said to be the most elaborate and time-consuming finissage technique.
The Handwerkskunst has been dubbed an exclusive collector’s item by Lange and is limited to 30 watches that are distributed exclusively through the seven A. Lange & Söhne boutiques worldwide.
