The new era of the mechanical watch

The ZEITWERK is the first mechanical wristwatch that displays hours and minutes with jumping numerals. Its trailblazing design expresses the innovative concept. The time bridge is one of the most prominent design elements of its dial. It is part of the movement and constitutes the stage for all time indications. The apertures for the hours and minutes are arranged from left to right; the large numerals are crisply legible. With its ingenious digital display concept, the ZEITWERK sets itself apart in the plethora of analogue mechanical watches, establishing a category of its own.

When they developed the ZEITWERK, Lange’s engineers questioned everything – except the mechanical paradigm. The result is a digital-display watch that no doubt ranks among the most progressive timepieces of our epoch. Its trailblazing concept with mechanically driven, precisely jumping numerals is unparalleled in watchmaking and appeals even to individuals who could not imagine that they would ever wear a digital timepiece.

ZEITWERK – the new era of the mechanical watch

Digital display – mechanical movement

In the past, the concept of the mechanical digital watch was implemented on several occasions but never in a really reliable manifestation. Lange’s masters solved the conceptual challenge with a jumping numerals mechanism that consists of three discs. The tremendous force needed to advance the discs is delivered by a patented mainspring barrel, and the precise timing is controlled by a patented constant-force escapement.
