<p>An analog time-indicating device (10), such as a watch, which can be read from either of two opposite view points, has time information displayed on its face in a circular array of twelve hour-representing indicia of which two diametrically opposite indicia (36, 32), visually distinguishable from each other, serve to indicate first and second twelve o'clock reference positions. The watch has two sets of hour and minute hands (20, 30), corresponding hands of which are displaced from each other by 180°. The sets of hands (21, 30) are visually distinguishable from each other by size and color and are coordinated by color with the indicia representing the twelve o'clock reference positions to give an observer visual information for matching a set of hands with the twelve o'clock reference position appropriate for correct time indication.</p> |
