Notes

Dial, case and cuvette signed, movement numbered. DIAM. 55 mm. Literature: Reinhard Meis, A. LANGE & SÖHNE, The Watchmakers of Dresden, 1997, p.248. The watch with the ascending number 42624 is illustrated and described p. 248, p. 672 - 673. LANGE DOUBLE-CHRONOGRAPH SYSTEM WITH SINGLE PUSH-PIECE LANGE & SÖHNE is one of the few manufacturers to have produced a double chronograph with single push-piece governing all four functions via one column-wheel. The first pressure starts both hands together, the second stops the fly-back, the third stops the chronograph-hand and the fourth zeroes them together. The stopping and zeroing of the hands is by the calipers used in all split-seconds chronographs. However, unlike the usual split-seconds chronograph, the double-chronograph cannot take intermediary times.
