From its beginnings, A. Lange & Söhne has been at the forefront of technical advancements and precision quality timing. While the firm collapsed during World War II and the ensuing “cold war” years, Walter Lange, the great grandson of the founder Ferdinand Adolph Lange, breathed new life in to the firm, and today it is known both for it classic wristwatches as well as being a disruptive force, bring 21st century technology to horology.

First introduced in 2009, the Lange Zeitwerk with digital display was not only a game changer for its creative design but also for its technical craftsmanship. Paying homage to the Dresden Semper Opera house clock with a five-minute digital display, the Zeitwerk’s trailblazing concept is the first mechanical wristwatch with three-disc jumping numerals mechanism, and a constant force mechanism enabling a controlled flow of energy to power the jumping hour and minute discs of the “time bridge” display. The present ref. 140.029 featuring a black dial in contrast with its sophisticated white gold case is certainly a revolutionary way of telling time on a mechanical timepiece. Symmetric in design with the balance of the UP/DOWN power reserve at 12 o’clock and the a small seconds at 6 o’clock, the aesthetic is absolutely pleasing. Flipping over to the rear to the timepiece reveals the beloved L043.1 movement that captures collector’s hearts bearing the signature engraved balance bridge. Offered in an absolute unworn “new-old-stock” condition with its original protective sticker still intact. The present Zeitwerk date with all its original accessories is absolutely a stunning example of contemporary time keeping.
