The Grand Complication is a luxury wristwatch and also the most complicated watch from A. Lange & Söhne.

Presented 2013, this model is inspired by the pocket watch Grande Complication No. 42500 from 1902. It features a large and small chime, a minute repeater, a perpetual calendar and a rattrapante chronograph function with flashing seconds. The assembly and fine-tuning of the mechanisms is so complex that only one watch is made per year and only six examples in total.


The large and small chimes strike the time after a quarter of an hour has elapsed. The minute repeater is started by operating the slide at 8 o'clock. The striking mechanism has its own barrel, which provides striking power for 24 hours.

Perpetual calendar

The small golden hands of the calendar indications show the date, day of the week, month and leap year.

Rattrapante Chronograph

The small blued hands and slim pair of center hands represent the rattrapante chronograph function. The power requirement of the flashing seconds is so high that it can only be met by its own barrel.

Based on the dial design, Lange counts the watch as part of the 1815 family.
