Patents of A. Lange & Söhne (6/9)
With their precisely jumping numerals display, all the ZEITWERK models stand for uncompromising clarity of design. Consisting of three discs, the display module is arranged in such a way that the time, with large-format numerals, can be read from left to right in the natural way. With a gentle click and hardly discernible to the human eye, the constant-force escapement advances the patented jumping numerals mechanism from minute to minute until, at the top of the hour, all three numerals discs simultaneously jump forward by precisely one increment.
