Preowned in 41.9mm white gold casing and manual winding movement. 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. Comes complete set with box and cert. Warranty dated December 2014.
