In 2009, A. Lange & Söhne presented the first ZEITWERK to the amazement of the world of horology. The unprecedented wristwatch concept features large jumping numerals for the hours and minutes as well as a constant-force escapement as a beat controller. To this very date, the clear, avant-garde display of time is peerless. It underscores the manufactory’s ambition to constantly redefine the limits of technical feasibility. Company founder Walter Lange repeatedly urged the need “to never stand still”. Following this maxim, the watchmakers at A. Lange & Söhne regularly question conventional concepts and pursue new innovative approaches to promote the development of precision watchmaking.
