Northern Aurora Lange Explores Polar Wonders With Three Luminous Watches In Iceland

Aurora is an amazing natural phenomenon: fluorescent aurora cuts through the stars and puts on a mysterious green veil for the night. Lange brings three watch masterpieces to Iceland, looking for the magnificent wonders of nature, and enjoying the charming scenery contrasted by light and darkness in a natural and pure environment.

Aurora shines brightly: GRAND LANGE 1 ‘Lumen’, ZEITWERK ‘Luminous’, GRANDLANGE 1 MOON PHASE ‘Lumen’
   The northern lights over Iceland present a perfect contrast. The contrast between light and darkness is the ideal stage for the three Lange watches with luminous function. One of the three Lange masterpieces that participated in the Nordic adventure this year, one of them is the GRAND LANGE 1 MOON PHASE ‘Lumen’, which appeared in January 2016. This is the third Lange watch with a translucent sapphire crystal dial after ZEITWERK ‘Luminous’ and GRAND LANGE 1 ‘Lumen’. Its light-transmissive coating allows digital time markers to absorb enough light and continue to shine for up to several hours in the dark.

How luminous display works

   Watches with a luminous display require a light source to add energy to the luminous coating of the display component, which in turn makes it glow. Thanks to the translucent black dial and clever devices, the display of the GRAND LANGE 1 MOON PHASE “Lumen” and other Lange luminous watches can permanently absorb the required light energy.
   Dial in solid black silver with large window and translucent black sapphire crystal. The special coating of the table mirror can block most visible light except the ultraviolet light in the spectrum, and it is a luminous material for the large calendar device, which ‘absorbs energy’ and emits light in the darkness. The crossed ten-digit plate is painted with white luminous material and printed with black numbers. The single-digit dial also printed with black numbers is made of transparent glass and rotates in front of the luminous background of the date window.
   The moon phase disk is made of glass. The glass surface is first coated with a patented process. Then laser cut out 1,164 stars and moon patterns. The luminous material behind the moon phase disc shines the moon and stars. The large moon phase display occupies a prominent position on the main dial. When set correctly, this display only needs to be corrected for one day every 122.6 years.
Why the northern lights are green
   This precious natural wonder can be seen in the polar regions on certain days between September and March each year. The colorful aurora is formed by the complex physical processes of the Earth’s upper atmosphere. Green aurora will be released at a height of about 100 kilometers, and our eyes are more sensitive to these green lights. Oxygen atoms collide with charged particles from the solar wind here. These impacts produce light with a wavelength of 557.7 nanometers, which is the green color seen by the naked eye.
Filming locations
Vic Town-Black Beach
   Fascinating black: The beach in Vík í Mýrdal is made of black lava. The huge basalt volcano is located on the icy Icelandic coastline. Here is the perfect setting to showcase three Lange “Lumen” watches: the black dial becomes the ideal backdrop for 18K yellow gold rhodium-plated hands, inset graduations and green luminous displays. The watch is extremely legible in contrast.

Langjökull-mountains and glaciers

   Where hot and cold meets: Glaciers covering one-tenth of Iceland’s surface are the focal point of this island. The largest is the Vatnajökull, which covers an area of ​​8,100 square kilometers. At the bottom is one of the island’s most active volcanoes. The extreme alternation of cold and hot is also a major feature of Lange’s ‘Lumen’ models. The platinum 950 used in the case needs to be cast into a mold when it is melted after being heated at about 1,800 degrees Celsius. The next step is to flatten the material to the final thickness of the bezel, middle case and bottom cover. The metal cools evenly to room temperature within 30 minutes, and thus becomes exceptionally strong.

Hukadaolu-Valley of the Geysers
   Steam Power: The Stokkur Fountain is the most prominent geyser in the entire Haukadalur geothermal area and erupts every 15 minutes. Hot spring water and steam can surge to an altitude of 35 meters. Various minerals, metals and plants can be found near the fountain. Sunlight refracts the deep hues of sulfur, iron, and moss. Steam plays an important role in the production of GRAND LANGE 1 MOON PHASE ‘Lumen’: the coating of the dial and the moon phase is processed by a patented vapor deposition process, which makes the details more beautiful and the colors more beautiful.
