The Secret Life of Machines Season 2 Episode 3: The Secret Life of the Quartz Watch 1991

Watch Tv Show Series The Secret Life of Machines : All clocks and watches work by 'counting' some event which takes a fixed period of time, like the swings of a pendulum. The higher it goes the stronger the pull of gravity and the faster it comes back - so the swings always take a fixed time. The Quartz crystal in a watch vibrates at a fixed speed in a similar way. Episode Contents: Models: A stick. Demonstration of liquid crystal technology with metal coated glass plates and polarized sunglasses. Machines: Many of Tim's large outdoor clocks. A water clock by Rex. Guests: A 400 year old pendulum alarm clock. Various antique pocket watches. Different watch models track the evolution of quartz and digital watches. Films: Goofy 1940's wristwatch commercial ("Hey kids come on a running!") Almost as silly 70's ad for the first bulky LED watch. Extro: Oven door blooper and a melting digital watch..
