Leonard de Vinci has been fascinated by the exhaust mechanisms that measure time. He studied a number of them. Based on his work, the new Academy model uses the laws of movement and a \"steering wheel\" exhaust pendulum to keep a specific hour. The weight of the pendulum acts as a source of diet of the clock. This model does not require glue for its assembly or battery to obtain the movement. It is a fascinating and easy to assemble functional model. Available in May 2016.
