The ZEITWERK is A. Lange & 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.
