Official description

In 1999, the DATOGRAPH ushered in a new era for the complication of short-time measurement, with a manufacture calibre newly developed from the ground up and a unique dial design. To mark its 25th anniversary, the pioneering chronograph is now available as a DATOGRAPH UP/DOWN model version in 18-carat white gold with a blue dial, limited to 125 watches.

It signified the birth of a trailblazing concept: in 1999, a mere five years after the first collection was launched, A. Lange & Söhne presented the DATOGRAPH ‒ equipped with their very first chronograph movement. The calibre L951.1, newly developed in the Saxon manufacture, combined a column-wheel chronograph with a flyback function, a precisely jumping minute counter and the typical Lange outsize date.

At a very early stage, the movement of the DATOGRAPH revealed the ambition of the Saxon manufacture to push horological boundaries and to explore new avenues. The DATOGRAPH was the prelude to a range of currently 13 innovative models with a chronograph function. Among these is the calibre L951.6 of the DATOGRAPH UP/DOWN: presented in 2012, it was consistently evolved with a power-reserve indicator and an increased power-reserve of 60 hours.
