Since 2010, the 1815 CHRONOGRAPH has been a paragon of classic design combined with advanced technology. Paying tribute to the 200th birthday of F. A. Lange, the founder of Saxon precision watchmaking born in 1815, the timepiece takes centre stage with an exclusive case and dial combination. This special white-gold model features blue numerals and a pulsometer scale. The 306-part chronograph movement is a paragon of mechanical ingenuity and aesthetics. In addition to the flyback mechanism, the sapphire-crystal caseback reveals a stepped snail for the precisely-jumping minute counter and a column wheel that controls the chronograph functions.
