Clock has any usage. It can be used to neutralize Sha Qi 化, block Sha Q i挡杀, counter 斗杀 and
neutralize 花病. Different
material and different shape will have different effect.
Hanging above door frame is for you easily to see but not
necessary however should be at least above 6 feet.
Your battery operated wooden pendulum
clock is wood + fire on the North which is water. From this point of view it is
fine as water produces wood produces fire. Yellow clock is earth by its color
at SE which is wood is not so beneficial. Again you also have to see the material
and shape.
Cheers.
