Langue Moon Phase Watch Only Needs To Be Corrected One Day Every 122.6 Years

In front of Andreas Cellarius’s famous star map ‘Harmonia Macrocosmica’, five watches with moon phase display are displayed.

 ‘Blue moon’ refers to the second full moon that occurs in a particular calendar month. This rare phenomenon occurs on average every two and a half years. For simplicity, most mechanical moon phase displays reduce the time between two new moons to 29.5 days, which is 44 minutes and 3 seconds less than the actual time. These displays must therefore be corrected for one day when the ‘blue moon’ appears.

 Fascinating on both sides: RICHARD LANGE PERPETUAL CALENDAR ‘Terraluna’ with track moon phase display, placed on the star map of Andreas Serrarius.

 The Lange Moon Phase watch is more accurate, and most of them have an accuracy of 99.998%. The new Grand Lange 1 Moon Phase is one of them. It shows that only one day of correction is required every 122.6 years. And Lange’s product research and development personnel have even improved the accuracy: The RICHARD LANGE PERPETUAL CALENDAR ‘Terraluna’ trajectory moon phase launched this year shows an error of only one day every 1058 and shows the position of the moon relative to the earth and the sun.

 Lange Watch Factory has successfully developed 15 movements with moon phase display since 1994. Five of the current collections of high-precision watches are equipped with this device and other complications, and were deliberately shot in front of the fascinating star map ‘Harmony of the Universe’. This star chart was drawn in 1660 by Dutch mathematician and map scientist Andreas Serrarius, born in Germany. This background highlights the close relationship between astronomy and watchmaking: when creating watch with astronomical complex devices, watchmakers are trying to imitate the actual shape of the celestial body, and strive to be accurate.

 From today’s perspective, the rich drawing of Serrarius clearly illustrates the fundamental changes that have occurred in the past two thousand years of human observation of the world, that is, from Ptolemy’s theory of the earth’s center at the center of the universe, which has gradually evolved into the present universe. Expansion theory.

 The patent pending RICHARD LANGE PERPETUAL CALENDAR ‘Terraluna’ track moon phase display is a new masterpiece in the field of precision watchmaking. This extremely accurate device depicts the position of the lunar trajectory relative to the earth and the sun. Its operation is based on calculations by Danish astronomer Tycho Brahe (1546-1601) to determine the trajectory and height of stars. Before the telescope was invented, his observations of the planet’s position were the most accurate.

 The moon is the focal point of GRAND LANGE 1 MOON PHASE. The hour and minute circles show rich details of the moon’s profit and loss. This is very close to the theory of Serrarius, which had been well-established until the 17th century. This theory means that the moon moves on a small circular trajectory (this round), and then rotates around the earth along an eccentric path.

 1815 RATTRAPANTE PERPETUAL CALENDAR combines technical stopwatch with stopwatch and precise and permanent perpetual calendar. The background is Ptolemy’s geocentric system. This theory speculates that the earth is the invariant center of the universe and was not overthrown by the Copernican revolution until the 16th century.

 SAXONIA ANNUAL CALENDAR aims to arrange different displays in a clear and harmonious way. In this picture of Earth and astral trajectories imagined by Tycho Brahe, the watch occupies the position of the sun. The Danish astronomer also believes that the earth is the stationary center of the universe, and the sun, moon and stars move along their own trajectories. He also believed that all planets except the Earth revolved around the sun.

 DATOGRAPH PERPETUAL cleverly integrates the flyback chronograph and perpetual calendar. The background pattern is the Ptolemy system drawn by Andreas Serrarius, which contrasts with the complicated devices of the watch that record the current and permanent time.

 The original star map ‘Harmonious Universe’ edited by Andreas Serrarius (1596–1665), published in Amsterdam in 1660, is one of the most remarkable works in the history of astronomy. The celestial figure drawn by the German-born Dutch mathematician and cosmologist is carved on 29 large-scale copper engravings, which is the pinnacle of the golden age of cartography. These prints present Claudius Ptolemy’s geocentric theory, Nicolaus Copernicus’s heliocentric system, Tycho Brahe’s fusion theory, and The trajectories of the sun, moon, and planets, and the constellations of the northern and southern hemispheres. Cologne publishing company Taschen GmbH reprinted the annotated version of the Harmonious Universe in 2006.

About Lange
When Ferdinand A. Lange founded his watchmaking factory in 1845, it also laid the foundation stone for Saxony’s watchmaking industry. His precision pocket watches are still sought after by collectors around the world. After the Second World War, Lange’s century-old foundation was expropriated and confiscated by the East German regime. The great-grandson of the founder, Walter Lange, seized the opportunity and began the revival of Lange in 1990. Today, Lange produces only thousands of gold or platinum 950 watches representing the highest quality each year. All are equipped with an exclusive movement carefully modified and assembled by hand. Within 20 years, Lange has developed more than 40 watch-manufactured movements, leading the world’s leading watch brand. The brand is fruitful, introducing different innovative timing tools, such as LANGE 1 with the first large calendar display in general watches, and LANGE ZEITWERK with clear, easy-to-read, accurate word skipping devices. These two watches have also become Lange’s signature models.

The inscriptions ‘Montre d’ Aéronef’ and ‘Pilot’ on the plate represent early in the military and civil aviation industry, Zenith was already one of the manufacturers of altimeters and cockpit watches.
Dizzying craftsmanship
   At the center of the bronze case is an ‘engine’ drive known for precision: the EL PRIMERO 4069 movement. Born in 1969, this legendary movement leads the world in accuracy. The vibration frequency reaches 5 Hz, and the display is accurate to one tenth of a second. It can drive the central hour and minute hands, small seconds and chronograph functions, while ensuring a power reserve of up to 50 hours.
