The weight rotates about the axis of the spring, twisting it, instead of swinging like an ordinary pendulum. The force of the spring reverses the direction of rotation, so the wheel oscillates back and forth, driven at the top by the clock's gears.

If the string were pulling vertically upwards, then the spring force would be equal to the collar's weight. However, in this case there is another force besides the spring force and gravity that must be cancelled for the collar to be in equilibrium.
