A. Lange & Söhne, known for their popular time piece, Lange Zeitwerk have now produced a limited edition model that features a very special dial treatment. The dial in black-rhodiumed white gold features an extensive tremblage engraving. The time bridge, is made in German silver with a linear graining finish, thus providing a nice contrast to the tremblage engraving on the dial. The A. Lange & Söhne signature case is platinum, as well as hand-engraved with the serial number. Limited to only 30 pieces worldwide, this timepiece is available only at the brand’s boutiques.
