Introducing the A. Lange & Söhne Zeitwerk Handerkskunst
A. Lange & Söhne introduced the world's first mechanical watch that featured a constant-force escapement to achieve a precisely jumping numerals display - the Lange Zeitwerk - three years ago. It has become one of their most popular timepieces. Since then there have been a few variations, including the Lange Zeitwerk Luminous, which you can read about here. Now, they have produced a limited edition model that features a very special dial treatment. The dial in black-rhodiumed white gold features an elaborate tremblage engraving.
"The engraver manually guides a specially crafted lining burin across the surface in precisely choreo- graphed multi-directional movements. This produces a delicate and highly vivid granular texture. A formidable challenge for the engravers: The curved A. Lange & Söhne logo and the filigreed lettering of the power-reserve indicator remain standing in sharply contoured relief."
The time bridge, which surrounds the hour, minute and second displays, is made in German silver , a material typically used for the movement components, with a linear graining finish - providing a nice contrast to the tremblage engraving on the dial.
The case is platinum and features the A. Lange & Söhne signature, the case number and the edition serial number on the caseback, which are hand-engraved.
This is an exclusive collector's item which is limited to 30 pieces worldwide, available only at the brand's boutiques.
