A. Lange & Söhne Zeitwerk minute repeater

Precision that can be heard

With the clockwork minute repeater, A. Lange & Söhne presents the first model with a chiming mechanism, that sounds tones at intervals of an hour, ten minutes and a minute. An app for implementation at trade fairs, at the POS and the website makes it possible to experience this master achievement in watch making. The greatest challenge: a multitude of animations (incl. 708 clockwork states) and sounds had to be exactly synchronized to create a visual and acoustic experience that is very close to A. Lange & Söhne's original masterpiece – in different resolutions, on different end devices and browsers. The iPad app also has different modes and is, for example, able to project the animation of the clockwork onto the back of a large clock installation or a wall using a second iPad and a projector.
