The A. Lange & Söhne Lange 1 Moon Phase “25th Anniversary” ref. 192.066 is a 25-watch limited edition with a price of Euro 44,400. Like the other models of the commemorative collection, the Lange 1 Moon Phase “25th Anniversary” is characterized by the interplay of silvery and blue hues on the signature, asymmetrical dial.
The sixth model of the anniversary collection created by A. Lange & Söhne to celebrate the iconic Lange 1 watch, which has turned 25 this year, is the Lange 1 Moon Phase.
Revamped in 2017, this model combines the satellite display with a fascinating day/night indicator.
Like the other models of the commemorative collection, the Lange 1 Moon Phase “25th Anniversary” is characterized by the interplay of silvery and blue hues on the signature, asymmetrical dial.
The gradated blue tones of the moon disc nicely harmonise with the thermally blued steel hands and the colour-matched inscriptions, including the numerals of the outsize date.
During the daytime, the moon is depicted against a bright blue starless sky; at night, it contrasts against the dark blue heavens with 383 sparkling stars.
Thus, the moon always shows itself against a realistic background that doubles as a day/night indicator. The combination of the moon-phase display with a day/night indicator has two layers. It consists of a solid-gold celestial disc with blue gradation. The disc completes one full revolution about its own axis every 24 hours, mapping the rhythm of day and night. Against this background, the white-gold moon performs its synodic orbit in 29 days, 12 hours, 44 minutes, and 3 seconds with such precision that it takes 122.6 years before a correction by one day is needed.
Housed in the classic and well proportioned 38.5 mm x 10.2 mm white gold case, the manually wound calibre L121.3 of the Lange 1 Moon Phase is based on the generic Lange 1 calibre L121.1 launched in 2015. The 70 additional parts for the moon-phase display and the day/night indicator were integrated in the movement so compactly that the watch is only 0.4 millimetres thicker and has an unchanged diameter of 38.5 millimetres.
Finished to the strictest Lange quality standards, the L121.3 beats at a frequency of 21,600 vibrations per hour with a power reserve of up to 72 hours, as indicated by the AUF/AB (UP/DOWN) inscription just above the moon phase display.
The anniversary number 25 is integrated in the manually engraved, blue-filled balance cock. As regards typography and form, it corresponds to the Lange outsize date which is set to 25 in all photos. The same number also refers to the strict limitations of all anniversary models.
As like all Lange watches, the movement is not assembled just once but two times. After the first assembly pass, it is taken apart and cleaned again in a quest for perfection.
In the second, final assembly phase, one single watchmaker is responsible for the entire movement. It is in this second assembly that all gold chatons are carefully inserted in the plate and the jig screws are replaced with thermally blued screws and the movement is finally ready to be housed in a precious metal case.
