It can be described in several ways, but elastic potential energy is the most useful.
A wound up clock contains potential energy, specifically elastic potential energy stored in the wound-up spring inside it. As the spring unwinds, this potential energy is converted into kinetic energy, which powers the clock's movement.
If there was no spring it would need some other kind of energy storage device. For example, a pendulum clock uses the potential energy of the pendulum in order to store the clocks energy. This is probably not the case in a toy, but it still needs an energy storage system.
Kinetic energy being converted to chemical potential energy
The hands moving on a battery-operated clock is an example of electrical energy being converted into mechanical energy to drive the clock's hands.
An electric clock typically uses electrical energy, which is converted into mechanical energy to power the movement of the clock hands. The electrical energy is provided by a power source such as a battery or a wall outlet.

clock spring
This refers to one particular kind of clock, the 400 day clock made by S. Haller and most typically marketed as an Elgin. Its flawed main spring design can cause the clock to explode when fully wound, and/or when someone is trying to repair it. Search 'German time bomb clock' for more data,

A clock is two simple machines: Gears are placed in the back of the clockThe Wheel and Axle is located in the hands of the clock.
A spring-loaded popgun stores potential energy in the form of elastic potential energy in the compressed spring. When the trigger is released, the spring expands and converts the potential energy into kinetic energy, propelling the projectile forward.
A coiled spring possesses potential energy due to its ability to store energy when compressed or stretched. This potential energy is stored in the spring as elastic potential energy, which can be released as kinetic energy when the spring is allowed to return to its original shape.
No, the energy stored in the spring of a jack-in-the-box is potential energy due to the compression of the spring. When the spring is released, this potential energy is converted into kinetic energy and gravitational potential energy as the jack pops out of the box and moves upwards due to gravity.
