A digital watch display system with a dual display element is provided, a liquid crystal for use in daylight, or bright light, and a light emitting diode for use in dim light. The light emitting diode display causes an over drain on the battery used for the watch. In order to minimize this, instead of the usual four digit LED display, two for hours and two for minutes, only two LED display digits are used and are alternately turned on to display hours and minutes.
