Lange 1 Moon Phase
A. Lange & Söhne 2017
Lange 1 Phases de Lune square
The Lange 1 Moon Phase became part of A. Lange &
Söhne's iconic range in 2002, completing the collection with this sought-after
astronomical complication. It now follows the Lange 1 in accommodating a new
movement with the addition of a representation of the moon combined with a
day/night indicator for a particularly realistic rendering. A separate moon in
solid gold progresses against a backdrop of a sky disc, also in solid gold,
that rotates once in exactly 24 hours. A gradient of light to dark blue
represents the different stages of day and night. During daytime hours, the sky
appears in light blue without any stars. At night, laser-etched stars stand out
against a dark sky. This precision moon, which requires correction by a single
day after 122.6 years, thus serves as a day/night indicator when setting the
time. This Lange 1 Moon Phase is proposed with a white gold case and a solid
silver, black dial, or in pink gold with a solid silver, silver-toned dial, or
in platinum with a solid silver, rhodium-plated dial.
