Lange 1 Moon Phase

A. Lange & Söhne 2017

Men's

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.
