Revelling In Northern Lights With A. Lange & Söhne

A. Lange & Söhne recently embarked on a journey to Iceland to witness up close one of Mother Nature’s most breathtaking phenomenon, the every-captivating Aurora Borealis or Northern Lights, fascinating impressions between light and darkness in primeval natural surroundings. Accompanying the brand on its exciting journey were three of its most spectacular models with their full luminosity, the Grand Lange 1 Moon Phase “Lumen” which was launched this January, the Zeitwerk “Luminous” and the Grand Lange 1 “Lumen”.

For the three luminous models, the Arctic nocturnal skies veiled in mysterious green swatches was the ideal setting to showcase the spectacular contrast between light and dark. Indeed, watches with luminous displays need a light source to charge the luminous compound applied to the display elements allowing them to glow. The semi-transparent black-tinted dials, coupled with an ingenious mechanism, allow the displays of the Grand Lange 1 Moon Phase “Lumen” and of the other “Lumen” models to be permanently charged with light energy.

The dial of the Grand Lange 1 Moon Phase “Lumen” is composed of blackened silver with wide apertures and a semitransparent black-tinted sapphire-crystal glass wafer. The special coating on the glass blocks most of the visible light but not the UV spectra that “charge” the luminous pigments. The tens cross -coated with a white luminous compound- and the units disc -made of transparent glass- are printed with black numerals. The glass lunar disc features 1164 stars and the moon, which are cut out with a laser beam and made to shine by the luminous compound. Once properly set, the moon phase only needs to be corrected by one day every 122.6 years.

The Grand Lange 1 “Lumen”, it is the third A. Lange & Söhne model with a semi-transparent sapphire-crystal dial. Its light-permeable coating allows the numerals to absorb a sufficient amount of light energy to uniformly glow in the dark for several hours. With this adventure, Lange brings one of nature’s most intriguing occurrences to one of its most captivating collections.
