At SIHH 2016, A. Lange & Söhne has come out with a limited edition Grand Lange 1 Moon Phase ‘Lumen’. Only 200 examples will be made and as its name would suggest, generates a special glow.

The dial of this limited edition model is made of blackened silver with tinted, semi-transparent sapphire-crystal glass. Using a special luminous coating, the watch glows in the dark.

The effects of the glowing bits on the dial are actually interesting. It shows a lot of the watch and has the effect like a light function on a digital quartz watch. For this piece, Normally, A. Lange & Söhne uses a moon phase disc made of lume-backed glass, which is then coated via a patented process that turns the surface of the glass black. The disc is then passed under a laser beam that accurately cuts out 1164 stars and the moon.  Once properly set, it only needs to be corrected by once every 122.6 years.

In typical Lange 1 fashion, the hours and minutes are offset to the left in the largest sub-dial while a smaller seconds sub-dial is located below and to its right. The big date window is located near to the 1 o’clock position and the power reserve indicator is located at the 3 o’clock position. The dial is protected by sapphire crystal.
