Abstract (en)
[origin: EP1498790A1] The watch (1) has a control unit that determines a position of a selected celestial body in the sky and indicates the position by hands (10, 12). A rotating dial (14) is provided and on which is represented a map (16) of the sky. The hands have a shape such that their intersection or their point of conjunction permits to assign any point of the map of the sky represented on the dial. The map of the sky is a representation of the stars and constellations (20) particularly the zodiac constellations, visible from Earth.
