A. Lange & Söhne


140.029Zeitwerk Family

Devoted to mechanical ingenuity

The Zeitwerk is A. Lange and Söhne’s very first mechanical wristwatch with a digital time display format. Hours and minutes are indicated with jumping numerals that always deliver a precise reading. The dominant feature of the watch is the time bridge, which as part of the movement penetrates the dial and simultaneously constitutes the frame for all time indications.

Detailed features & specifications

This model was introduced in 2009. The dial is crafted from solid silver, the time bridge from rhodiumed German silver. The hands are made of rhodiumed gold.

The ZEITWERK is the first mechanical wristwatch that displays the time digitally with jumping numerals that allow unambiguous legibility at all times. In addition to a tens- and a units-minute disc, the jumping numerals mechanism is endowed with a large hour ring that spans almost the entire diameter of the movement. All numerals are identical in size and arranged for natural left-to-right reading.

When we developed the ZEITWERK, we questioned everything – except for the mechanical heart. The result is a digital-display watch with a jumping numerals mechanism. Its most salient design feature is the time bridge. Framing the displays of hours, minutes and seconds, it is a component of the movement that penetrates the dial in this place.
