Abstract: A horological device designed to indicate the position of a celestial body or planet in the sky relative to the user. The horological device includes two hands, which rotate within the main plane of the timepiece to display the position of the celestial body or planet selected by the user. One hand is used to indicate the location of the selected celestial body or planet relative to the user's horizontal plane, while the second hand is used to indicate the location of the selected celestial body or planet relative to the user's vertical plane. Thus, the user can directly see the celestial body in the sky by following the directions given by the hands of the display system. The horological device can be used to display either the current time or position of the selected celestial body or planet by simply switching the mode of operation.
