The shape of grandfather clock follows the architectural style of European churches, with dignity and poise. In the 16th century, there were mechanical clocks with long pendulums with beautifully decorated clock shells, but they were not called grandfather clocks at that time. With the change of years and the continuous efforts of clock practitioners to improve, the grandfather clock has gradually evolved from a single timing product into a highly skilled work of art. Its solemn style and strong cultural heritage make it regarded by Western nobles and dignitaries as a hereditary heirloom.
Grandfather clock has existed for more than 500 years. The grandfather clock can run without electricity. The kinetic energy source of the pendulum and its function is to drive the movement by using the hanging weight of the pendulum hanging on the chain or steel cable pulley, so that the pendulum can swing continuously.
