A. Lange & Sôhne Datograph Up/Down in white gold with blue dial - Watches & Wonders 2024 #WatchesandWonders2024

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.

With its flyback mechanism, precisely jumping minute counter, outsize date and power-reserve indicator the DATOGRAPH UP/DOWN is in a league of its own.

Because three switching steps are executed with one single push of a button, the flyback mechanism allows two quick consecutive time measurements, with virtually no delay between these. The chronograph is stopped, reset to zero, and started again in next to no time. This function was often used in the early beginnings of aviation. The precisely jumping minute counter does justice to its name as well: it jumps to the next increment at the precise moment when the chrono seconds hand completes the 60th second.

The attribute “UP/DOWN” refers to the power-reserve indicator at 6 o’clock that provides information on how much of the 60 hours’ power reserve is still available. At the latest on the third day, when the hand pivots into the red section, it is time to wind the watch.
