In 2009, A. Lange & Söhne launched the ZEITWERK, a mechanical timepiece with a digital time indication, realized by jumping numerals. “At that time, we thought that it would be a unique piece of our collection”, remembers Anthony de Haas, Director of Product Development at the German watchmaker. However, the new concept turned out to be so successful that a new watch family grew out of it, consisting of seven different models today.

At the June 2021 meeting of the Horological Society of New York, Anthony de Haas and watchmaker Robert Hoffmann, Head of the ZEITWERK Assembly Department, will talk about the synergy between dial and movement design, the power of constant-force escapements and how tradition inspires today’s watchmaking.
