A. Lange & Sohne Grand Lange 1 “Lumen”


Electromagnetic radiation at wavelengths between 100 and 380 nanometres is commonly referred to as ultraviolet light. It is not visible as such to the human eye. It penetrates the semi-transparent dial of the GRAND LANGE 1 MOON PHASE “Lumen” and charges the luminous elements, even those that are not yet exposed. The result: the first Lange watch featuring a luminous moon-phase display and a luminous outsize date.
