ZEITWERK HONEYGOLD “Lumen”

Time, exceptionally composed.

The ZEITWERK HONEYGOLD “Lumen” is an incomparable horological composition that combines three exceptional features: It has the ZEITWERK-style jumping numerals display consisting of three discs. The large, highly legible numerals read from left to right, as usual in a digital watch. Also, the ZEITWERK HONEYGOLD “Lumen” has luminous numerals that can easily be recognised in darkness. The third special facet of this watch, limited to 200 pieces, is the 41.9-millimetre case made of warm shimmering honey gold, an alloy composed exclusively for A. Lange & Söhne.

With a gentle click, the new manufacture calibre L043.9 instantly switches the numerals display of the ZEITWERK HONEYGOLD “Lumen” from one minute to the next until, at the top of the hour, the sophisticated mechanism simultaneously switches all three numerals discs by one increment. Two mainspring barrels deliver the power needed for switching. The switching point is controlled by a patented constant-force escapement. It also assures that the balance is always driven with constant power. The movement has twice the power reserve of its predecessor model – 72 hours. The pusher at 4 o’clock allows the hour indication to be switched separately, which in turn makes it simpler to set the time.

The ZEITWERK HONEYGOLD "Lumen" is an incomparable timepiece that features a luminous jumping numerals display and a case made of Lange-exclusive honey gold.

Anthony de Haas, Head of Product Development at A. Lange & Söhne, introduces the new ZEITWERK HONEYGOLD “Lumen”.
