Vincenzo Galilei, the son of Galileo invented the pendulum clock in 1641. He realized the pendulum, at regular oscillation periods would make an efficient and accurate regulator of clock movement. Vincenzio’s clock design was improved upon by Dutch mathematician and astronomer, Christiaan Huygens in 1656. The weight-driven, pendulum-regulated led to smaller and less expensive wall clocks priced for the public.

• Galileo’s escapement – Wikipedia
  Galileo’s escapement is a design for a clock escapement, invented around 1637 by Italian scientist Galileo Galilei (1564 – 1642). It was the earliest design of a pendulum clock. Since he was blind, Galileo described the device to his son, who drew a sketch of it.
• Galileo and the pendulum clock
  Jul 8, 2009 – At the end of his life he devised a scheme for using a pendulum to regulate a mechanical clock. However, the first reliable pendulum clock was only demonstrated by Huygens 15 years after Galileo’s death. Vincenzo Vivani became Galileo’s assistant in 1639. He went on become an important mathematician in his own right.

  After decades of experiments with the pendulum, Galileo Galilei (1564-1642) conceived of a pendulum clock that could be used to determine longitude at sea. Near the end of his life, blind and in failing health, he discussed the design with his son Vincenzio and his biographer Vincenzo Viviani.
