DATOGRAPH UP/DOWN

For more than a decade, A. Lange & Söhne's DATOGRAPH was considered by many to be the quintessential chronograph. On the one hand, it was because of its technical features, on the other because of the unparalleled harmony of its dial. With a number of enhancements, Lange's engineers are now proving that excellence can be taken a step further. With a power reserve extended to 60 hours, a power-reserve indicator, and a proprietary oscillation system, the new DATOGRAPH AUF/AB shines in a platinum case enlarged to a diameter of 41 millimetres.
