Official description

With the 1815 RATTRAPANTE PERPETUAL CALENDAR, A. Lange & Söhne presents three of the most sophisticated watchmaking complications in a classic design. The equally rare and ambitious combination of a split-seconds or rattrapante chronograph with a perpetual calendar now appears in a new guise, featuring an 18-carat white gold case with a pink-gold dial. The new 1815 RATTRAPANTE PERPETUAL CALENDAR is limited to 100 pieces.

With its launch in 2013, the 1815 RATTRAPANTE PERPETUAL CALENDAR marked a milestone in A. Lange & Söhne’s more recent history: no less than seven chronograph calibres had previously been crafted by the Saxon manufactory. Equipped with a specially developed movement, it united three of the most elaborate complications – very rare in this configuration – while maintaining the classic, elegant design of the 1815 watch family. The outstanding timepiece excels in the measurement of short and long distances: thanks to its eponymous complications, the 1815 RATTRAPANTE PERPETUAL CALENDAR sets standards in both short-time measurement and the display of calendar periods.
