This displays the count of seconds, minutes, hours, etc. in a human readable form.
* The earliest mechanical clocks in the 13th century did not have a visual indicator and signalled the time audibly by striking bells. Many clocks to this day are [[striking clock]]s which strike the hour.
* Analog clocks display time with an analog [[clock face]], which consists of a dial with the numbers 1 through 12 or 24, the hours in the day, around the outside. The hours are indicated with an [[hour hand]], which makes one or two revolutions in a day, while the minutes are indicated by a [[Clock face|minute hand]], which makes one revolution per hour. In mechanical clocks a gear train drives the hands; in electronic clocks the circuit produces pulses every second which drive a [[stepper motor]] and gear train, which move the hands.
* [[Digital clock]]s display the time in periodically changing digits on a digital display. A common misconception is that a digital clock is more accurate than an analog wall clock, but the indicator type is separate and apart from the accuracy of the timing source.
* [[Talking clock]]s and the [[speaking clock]] services provided by telephone companies speak the time audibly, using either recorded or digitally [[Voice synthesis|synthesized voices]].
