A digital display driven mechanically. Numerals sit on jumping discs behind three windows and all advance at once, which needs far more energy than sweeping a hand — so Lange added a constant-force escapement that stores and releases power in one-second steps, both to fire the jump and to keep the rate steady while doing it. The bridge across the dial is the structure holding the whole arrangement together.
