A. Lange & Sohne Zeitwerk Luminous Watch
Basically they made the dial out of a tinted (smoked) sapphire crystal. The numerals all have luminant applied to them. The sapphire part of the dial is made so that it is not totally transparent, but light can enter easily to charge the luminant. When the indicators are displayed in the digital windows, they should be able to charge enough, provided that the watch has been exposed to enough light. Thus you have a lume version of the Lange Zeitwerk - clever.
Aside from that the watch retains the features that we love about standard Zeitwerk. It comes in a 42mm wide case in platinum and is part of a limited edition of just 100 pieces. Movement is the highly complex manually wound in-house made A. Lange & Sohne Caliber L043.1, with its double constant force escapements. Functions include the hours and minutes digitally, with a subsidiary seconds dial and a power reserve indicator. A beautiful watch with a great appeal somewhere between luxury gadget and traditional fine timepiece. Price is $91,200, and the watch is in platinum as mentioned.
