With its one-of-a-kind design, sophisticated manufacture movement and artisanal finish, the LANGE 1 epitomises the essence of A. Lange & Söhne. The new model versions of the LANGE 1 and the LITTLE LANGE 1 radiate festive elegance – as befits the anniversary. The watch in 950 platinum showcases a dial faced with onyx. This gemstone, which is rarely used in fine watchmaking, captivates with its jet-black shimmering surface: it is the first time that it adorns a LANGE 1 model. In the 750 pink-gold version, the warm, reddish lustre of the precious metal is paired with a blue dial in 925 silver. All four limited-edition models exhibit the exceptional lucid design with slender bezels and prominent lugs. The case diameter of the LANGE 1 amounts to 38.5 millimetres and to 36.8 millimetres in the LITTLE LANGE 1.
