Da Vinci's "Clock at Chiaravalle"

One of Leonardo da Vinci's Clock designs was created and put on display in Chiaravalle, Marches, Italy. It includes three dials, or 'clock faces:' one for minutes, one for hours, and one to keep track of lunar phases. Although clocks that keep track of seconds were not invented after pendulums were introduced to clockwork, after the life of da Vinci, he created arguably the most accurate clocks in his time.
