A movement is installed in the case for driving the hour indicating hand to rotate one revolution in 24 hours. A time setting device is installed in the case for setting the time equipment on time. The dial has an hour portion, a minute portion and a period portion, in which the hour portion inscribes two sequences of numerals ordered by increasing value from 1 to 12. The minute portion is positioned adjacent to the hour portion and inscribes a sequence of numerals ordered by increasing value from 1 to 60. The period portion is position at the central area and encircled by the hour portion, which has a central cross inscription having a vertical line extending from top to bottom and a horizontal line extending from right to left so as to divide said period portion into four sections. An alarm generating mechanism can provide more than one alarm signal at predetermined time. An alarm time setting assembly is installed in the case for setting the predetermined alarm time. A switch device is installed in the case for stopping the alarm signal when generating. Therefore, the time equipment enables more than one alarm time setting in 24 hours, enables the users to observe at one time an exact time indicating hours, minutes, seconds, day or night, am or pm, and various time periods in form of morning, afternoon, evening, and night, and can simultaneously indicate the time for a plurality of times zones.
