Abstract
A clock with dual time-indicators, one of each of the indicators being located at a transparent face at opposite ends of a clock casing, includes a drum which is mounted within the casing and is driven by a motor at a rate of one revolution per each twelve hour period or multiple thereof. One time indicator is provided by dial markings on one of the transparent faces, an hour hand marked on one end of the drum, and a minute hand disposed between the dial markings and hour hand. The other time-indicator is provided by dial markings at the other end of the drum and a line marker on the other transparent face.
