Electronic circuits with manual controls (21,22) provide a time base, calculation of time and date, and storage of astronomical data. At current or any other indicated time the position of the Sun and Planets may be shown relative to Earth and Zodiac. A particular display device comprising two hands (14,15), a revolving window (23) and a face (16) is marked with hours and minutes (17), Zodiac signs (18) and Moon phases (19). |
