The Lange Zeitwerk series of timepieces launched by Lange at the SIHH Geneva Haute Horlogerie Salon in 2011 has conquered the hearts of many watch enthusiasts with its excellent all-mechanical jumping hour and minute display, and may also be registered On the Shopping List of all fans of Lange watches.
Five-minute digital clock prototype of the Semper Opera House
In 1841, Johann Christian Friedrich Gutkaes, the watchmaker and court watchmaker, took on this difficult task. The biggest challenge of this task is to design a clock that can clearly read the time in all auditorium seats, even in the dark. Since the clock needs to be suspended in a space only two meters high on the front arch, a circular clock dial is not feasible. For this reason Gut Case made a wonderful plan, hoping to design a digital display clock. The clock has two 1.6-meter diameter reversing rollers in the opposite direction, and the double windows above the stage show the time. The hours are displayed in Roman numerals on the left and the minutes are displayed in Arabic numerals every 5 minutes on the right.

1841 was also the year when Ferdinand A. Lange returned from a tour of European precision watchmaking. He became a watchmaking apprentice at Gut Case at the age of 15 and then went to Paris, where he began his journey to England and Switzerland 4 years later. Lange, who was full of innovative ideas, returned to Gutkes’s workshop again and also contributed a lot to the design of the five-minute digital clock (Five-Minute clock). This special digital clock still has a great influence on the movement engineers of Lange A. Lange & Sohne. After 1990, A. Lange & Sohne engineers organized their thoughts, first creating the iconic large calendar of Lange 1, inheriting the name of historical paradigm; then the brand put the word jump time display on the mechanical watch, creating Lange Zeitwerk .
Due to the size limitation of the watch movement, the engineer decided to set the digital time display in two adjacent windows to create more space for the large-sized digital dial. The German Silver Time Bridge forms the framework for all time displays, making their dreams come true with this groundbreaking design element. Unprecedented display amplitude can accurately report time. The minute wheel splint is on the top level, and above the hour circle, the three dials advance simultaneously. The clockwork of the new bearing system provides the watch with the energy required to rotate the dial. The constant-power escapement, mounted between the barrel gear and the balance wheel, is unrivalled in its simplicity and simplicity, and acts as a pacemaker for the watch.

Lange Zeitwerk is not only an important milestone attributed to the Lange watchmaker, but also a prototype of numerous award-winning design examples, including the Geneva Grand Prix of Fine Watches and the Golden Finger Award.
