LANGE 1 MOON PHASE “25th Anniversary”
The sixth model of the anniversary collection shows the moon by day and by night
In 2017, with the LANGE 1 MOON PHASE, A. Lange & Söhne took a new approach to depicting the moon phases by combining the eponymous astronomical display with a day/night indicator. To mark the occasion of the 25th anniversary of the LANGE 1, it is now being presented in an exclusive 25-watch limited edition in white gold with blued steel hands.
The moon stands out especially in the dark. By day, the sun usually outshines it, but even then, it accompanies us. The LANGE 1 MOON PHASE makes that visible. 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. This makes it easier to set the time because it assures that the date switches at midnight and not, inadvertently, at 12 noon.
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.
An exciting interplay of silvery and blue hues unfolds on the asymmetrical, argenté-coloured dial. The thermally blued steel hands and the colour-matched inscriptions harmonise with the gradated blue tones of the celestial disc. The watch features a blue alligator leather strap with a solid white-gold prong buckle.
Finished to the strictest Lange quality standards, 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. It continues to stand out with the same technical features. They include a twin mainspring barrel with a power reserve of 72 hours, a power-reserve indicator with the UP/DOWN inscription and a precisely jumping outsize date display. The escapement, consisting of a cam-poised balance and a freely oscillating Lange balance spring, runs at a frequency of 21,600 semi-oscillations per hour.
Like all other models of the “25th Anniversary” collection, the LANGE 1 MOON PHASE is endowed with a special movement detail: 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.
About A. Lange & Söhne
Dresden watchmaker Ferdinand Adolph Lange laid the cornerstone of Saxony’s precision watchmaking industry when he established his manufactory in 1845. His precious pocket watches remain highly coveted among collectors all over the world. The company was expropriated after World War II, and the name A. Lange & Söhne nearly vanished. In 1990, Ferdinand Adolph Lange’s great-grandson Walter Lange had the courage to make a new start. Today, Lange crafts only a few thousand wristwatches in gold or platinum per year. They are endowed exclusively with proprietary movements that are lavishly decorated and twice assembled by hand. With 63 manufacture calibres developed since 1994, A. Lange & Söhne has secured a top-tier position in the world of watchmaking. Brand icons such as the LANGE 1 with the first outsize date in a regularly produced wristwatch and the ZEITWERK with its precisely jumping numerals display rank among the company’s greatest successes. Sophisticated complications such as the ZEITWERK MINUTE REPEATER, the TOURBOGRAPH PERPETUAL “Pour le Mérite” and the TRIPLE SPLIT reflect the manufactory’s determination to achieve ever new pinnacles in horological artistry.
