The Richard Lange Minute Repeater represents one of the most sophisticated achievements in A. Lange & Söhne’s history, combining the collection’s dedication to chronometric precision with one of watchmaking’s most celebrated acoustic complications. Activated by a traditional slide integrated into the case, the mechanism audibly strikes the hours, quarter hours and minutes on demand, transforming mechanical engineering into a captivating musical performance. Advanced safety systems prevent accidental misuse of the repeater while ensuring every sequence of chimes is delivered with exceptional clarity and reliability.

Powering this extraordinary creation is a hand-finished manufacture calibre assembled and regulated entirely in Glashütte. The movement incorporates an intricate network of racks, snails, hammers and polished gongs, each individually adjusted by master watchmakers to produce rich, harmonious tones. Visible through the sapphire exhibition caseback, untreated German silver bridges, hand-engraved balance cocks, mirror-polished steel components and thermally blued screws exemplify the Maison’s uncompromising finishing standards. Produced only in extremely limited numbers, the Richard Lange Minute Repeater stands among the rarest and most technically accomplished acoustic timepieces in contemporary haute horlogerie.
