The clock face is the circular plate, usually with numbers or Roman numerals inscribed on it, upon which the clock's hands rotate. There are usually three hands: an hour hand, a minute hand and a second hand. The rotation of the hands directly corresponds with the movement of the wheels.Clocks and watches typically consist of three wheels: the center wheel, the third wheel and the escape wheel. The center wheel rotates once per hour, the third wheel rotates once per minute and the escape wheel regulates how fast the mainspring unwinds.
