Leonardo's Sketch
Leonardo da Vinci sketched out the first clock. He didn’t invent the first clock he just designed it. His clock had to separate parts, one for hours and the other for minutes. It connected different weights, gears, and harnesses. It also kept track of different moon phases. He instead of using weights wanted to use springs. Some materials he wanted to use for the clock included diamonds and rocks. http://www.da-vinci-inventions.com/clock.aspx -
