ABSTRACT:
Seven symbol lamps are aligned, in addition to a six-digit numeral display for displaying time information, in order to indicate any one of the days of the week printed on a calendar panel. A mode panel is disposed, parallel to the calendar panel, on which labels representative of a month information correction mode, a date information correction mode, a day of the week information correction mode, an hour information correction mode, a minute information correction mode, and other operation modes such as a stop-watch mode are provided at positions corresponding to the seven symbol lamps. The symbol lamps are continuously enabled when they indicate the days of the week information printed on the calendar panel, and the symbol lamps are controlled to flicker when they indicate any one of the operation modes represented by the mode panel.
