PURPOSE: A wall clock, which can vary the fixed location of pendulum and which can minimize operation resistance, is provided to minimize battery consumption amount by continuously maintaining similar amplitude. CONSTITUTION: A wall clock, which can vary the fixed location of pendulum comprises a body(11), housing(15), a pendulum shaft(18), a hooking part(19), a speaker and a slot hole. A time display part is formed on the body. The housing is installed in the rear side of the body. The pendulum axis is made of metal material in order to minimize the operation resistance in the swinging of a pendulum(14). The hooking part is formed in the housing in order to fix the wall clock on the wall. The speaker is formed in the housing and generates melody sound. The slot hole is formed to be penetrated in the accommodating groove of the housing.
