In addition to the main functions listed below, the most complex of them may offer a system for predicting lunar and solar eclipses, the position of the stars as seen from the Earth, displays of the ephemerides (solstices, equinoxes, seasons), the signs of the zodiac, a tideograph, sunrise and sunset, the duration of day and night, the annual deviation or angular movement of the Moon, etc. The astronomical functions of a wristwatch include indications related to the particularities of the Gregorian calendar, as well as a wide variety of displays related to the movement of the stars. Since the 2000s, this technical mastery has been illustrated in particular through its Les Cabinotiers department, whose astronomical watches are masterpieces of their kind. From its earliest days, Vacheron Constantin has shown great interest in watches with astronomical functions, including various types of calendar displays and indications of the phases and age of the Moon, often combined with other horological complications. Although many of these functions are not of practical use, they nonetheless testify to expertise that is all the rarer in that it lends a cosmological dimension to these watches forming a link between humankind and the universe. This mechanically translated interpretation has given rise across the ages to timepieces capable of offering a wide variety of functions, and of varying degrees of complexity, linked to the singularities of the Gregorian calendar, to the various temporalities governing our universe, or to the motion of heavenly bodies and their impact on the Earth. Born of the observation of the great physical laws of Nature, the measurement of time is in fact a material extrapolation of the movement of the stars and cycles. Today, the Maison produces watchmaking masterpieces of great astronomical complexity.Īstronomical watches remind us of the origins of watchmaking. Founded in 1755, Vacheron Constantin developed a perfect mastery of astronomical indications at a very early stage, progressively enriching it over the two and a half centuries of the Manufacture's existence. The mechanical instruments developed by horologists stem from these observations, reflecting an art that has continued to progress since the late Middle Ages. Geneva, November 17 th 2021 – Horology, the science of time measurement, was born from the observations of heavenly bodies and natural cycles.

The Manufacture has developed a rare breed of expertise in Grand Complication watches dedicated to the movement and influence of the moon, stars and planets.Twenty years after its foundation in 1755, the first watches with astronomical indications appeared at Vacheron Constantin.Horology stems from the observation and study of the stars dating right back to the earliest ancient civilisations.
