An Astrolabe is an instrument used to indicate the positions of the sun, moon, and stars as seen from the earth. The Astrolabium Galileo Galilei, launched in 1985, is the only astrolabe watch designed to be worn on the wrist, and shows the wearer a number of accurate astronomical indications. They include the display of local and solar time, the orbits and eclipses of the sun and the moon and the positions of several major stars. This reference is part of Ulysse Nardin's Astronomical Trilogy consisting of the Astrolabium Galileo Galilei, the Planetarium Copernicus and the Tellurium Johannes Kepler models.
A similar watch is illustrated in Armbanduhren - 100 Jahre Entwicklungsgeschichte by Kahlert, Mühe, Brunner, 5th edition, p. 430, pl. 1478.
