Lange & Sohne Grand Complication

Inspired by the Grande Complication No. 42500, a pocket watch that dates back to 1902, A. Lange & Söhne presented its most complicated wristwatch in 2013: the GRAND COMPLICATION. This outstanding timepiece features a grand and small strike, a minute repeater, a perpetual calendar and a rattrapante-chronograph function with flying seconds. The assembly and the adjustment of the mechanisms are so intricate that only one watch can be crafted per year and only 6 of these masterpieces will be built altogether.
