The **1815 Chronograph** is a wristwatch by [[A. Lange & Söhne]].

After the [[1999]] published [[A. Lange & Söhne Datograph|Datograph]] Lange developed with the Lange calibre [[Lange L951|L951.0]] a new [[chronograph]] movement with classical, elaborate [[column-wheel]] mechanism, with [[flyback]] function and exactly jumping minute counter.

The series "1815" is named after the year of birth of [[Ferdinand Adolph Lange]]. The [[2010]] presented model "1815 Chronograph" is equipped with the further development of this movement the calibre [[Lange L951.5|L951.5]] with [[column wheel]] control and a stepped snail for the precisely [[jumping]] minute counter. It is undoubtedly one of the finest movements of the traditional [[Glashütte]] [[manufacture]], which thus underlines again its impressive primacy. A large [[barrel]] guarantees the remarkable [[power reserve]] of 60 hours.

The "1815 Chronograph" has a dial of solid [[silver]] and a case in [[white gold]] or [[red gold]]. The [[sapphire crystal]] sighting window in the caseback makes it possible to observe the magnificently [[finished]] movement at work.
