Leonardo da Vinci was interested in the escapement mechanisms for themeasurement of time to the degree of studying a great number of them. Thisswinging pendulum clock model is founded on the research and developmentsof his work and the numerous drawings and sketches produced by it. The kit usesthe legislation of movement and a “swinging” escapement pendulum to achieve aconstant motion that ensures accurate time dimension. The extra weight ofthe pendulum will act as the clock energy supply.
