Inspired by the decimal measurement of modern time, the Zeitwerk Decimal Strike replaces the traditional quarter-hour chiming sequence with an innovative mechanism that sounds every ten minutes. A crystal-clear high-pitched tone announces each ten-minute interval, while a resonant low note marks the passing of every full hour. This distinctive approach delivers exceptional legibility through sound while showcasing A. Lange & Söhne’s continual pursuit of mechanical innovation beyond conventional watchmaking traditions.

The sophisticated movement coordinating these acoustic indications also powers the signature jumping digital display through a constant-force escapement that guarantees stable energy delivery. Every visible component reflects the highest standards of Saxon finishing, from hand-engraved balance cocks to untreated German silver bridges and mirror-polished steel parts. The Zeitwerk Decimal Strike stands as one of the most original acoustic complications ever developed in contemporary haute horlogerie.
