The **Zeitwerk** is a luxury watch by [[A. Lange & Söhne]].

In the spring of [[2009]] A. Lange & Söhne presented this completely new development with the [[manual winding]] [[manufacture movement]] calibre [[Lange L043|L043.1]]. The watch has the unusual combination of a precisely jumping numerals indication of hour and minute and offers a new, yet very simple dial design, together with [[power reserve]] and [[small seconds]], arranged in calm tetrachord and gives the watch a unique look.

The inventions which are united in the movement, were registered with several patents so for the new [[barrel]] construction and the mechanics of [[constant-force]] [[escapement]].

There are three case variations in [[gold]] and one variant in [[platinum]]. The crown is placed on the top right.

In the spring of [[2010]] with the [[A. Lange & Söhne Zeitwerk "Luminous"|Zeitwerk "Luminous"]] a noctilucent variant with elegant design in gray and platinum case was presented.

In October [[2022]], a revised version appeared with the [[A. Lange & Söhne Zeitwerk (2022)|Zeitwerk (2022)]], with a power reserve doubled to 72 hours and other improvements.
