An apparatus for indicating time by means of a circular pointer movement over a dial includes a pointer arrangement having at least one first pointer and a second pointer. The at least one first pointer provides an indication of local time with a pointer period of revolution of twelve hours. The second pointer indicates a world time with a period of revolution of twenty-four hours by cooperation with a scale having a number of graduations which is a multiple of 24. A drive mechanism is coupled to the at least one first pointer and the second pointer, to cause the revolving movement of the at least one first pointer and the second pointer. Preferably, the at least one first pointer includes an "hour" hand with a period of revolution of twelve hours, a "minute" hand with a period of revolution of one hour, and a "second" hand with a period of revolution of one minute. In a preferred embodiment, the scale comprises 360 degrees or graduations. The apparatus may be constructed as part of a watch, but it may alternatively be used to advantage elsewhere, for example as part of a monitor screen of a PC, a mobile telephone, or an instrument panel in a car, train or airplane.
