The **Zeitwerk "Luminous"** is a wristwatch by [[A. Lange & Söhne]].

In the spring of [[2009]] A. Lange & Söhne had presented the [[A. Lange & Söhne Zeitwerk|Zeitwerk]], a completely new development with the unusual combination of an exactly jumping numerals indication of hour and minute, whose [[barrel]] design and [[constant-force]] [[escapement]] had been registered with several patents. For this unusual watch, affirming strong innovation force, Lange received several awards, including the top award at the prestigious [[Geneva Watchmaking Grand Prix]] the Special Prize "Golden Hand" or "L'Aiguille d'Or".

One year later, in the spring of [[2010]], with the "Luminous" a version of the //Zeitwerk// was published, which was easy to read even at night. Strikingly the time bridge in [[nickel silver]], coated with black [[PVD]], frames the windows of the hours and minutes indication, which are arranged on one plane. There the luminescent numerals coated with white [[Superluminova]] emerge out of the black fond. This is assured by a dial from dark-tinted [[sapphire crystal]]. Its translucent coating allows the numerals to absorbe enough light energy to dispense it again evenly in the dark for several hours.

As a movement again the classic [[manual winding]] manufacture movement [[Lange L043|Lange L043.1]], vibrating with 18,000 A/h, is used. The design of the watch, totally committed to light-dark contrasts, is emphasized by a platinum case with black crocodile band and a buckle also made of solid platinum.

This model is limited to a maximum of 100 pieces.
