The Zeitwerk Minute Repeater represents one of the most technically ambitious creations ever produced by A. Lange & Söhne. Unlike conventional minute repeaters that chime based on analogue hands, this remarkable timepiece reads the exact digital display and acoustically reproduces the displayed time on demand. Activated by a dedicated slide integrated into the case, the mechanism strikes the hours, ten-minute intervals and individual minutes with exceptional precision, making it the world’s first decimal minute repeater designed specifically for a mechanical digital watch.

Achieving this extraordinary complication required a completely re-engineered manufacture calibre capable of synchronising the jumping numeral discs with an intricate acoustic mechanism while maintaining consistent energy delivery through the constant-force escapement. The movement is assembled twice by hand and finished to the highest standards of Glashütte watchmaking, featuring untreated German silver bridges, hand-engraved balance cocks and flawlessly polished steel components. Produced in extremely limited numbers, the Zeitwerk Minute Repeater stands among the most exclusive and technically significant masterpieces in modern haute horlogerie.
