The Lange and Sohne Datograph Up/Down Plat Lumen,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 a single actuation of a pusher, 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 so-called speed-switching 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 A. Lange & Söhne Datograph Up/Down “Lumen” is a rare and coveted platinum timepiece celebrated for its luminous dial, which makes its complex mechanics readable even in the dark. As the fourth model in the “Lumen” series, this limited edition of 200 watches combines the iconic Datograph’s flyback chronograph with a unique semi-transparent sapphire crystal dial.
