Water Clock Water clocks may be as old as sun dials. This is a Greek Clepsdra, meaning Water Thief. (1500BC) Build-It-Yourself.com
6
Sand Clock Sand clocks (or hour glasses) were used in early ships for dead reckoning navigation. 300AD Build-It-Yourself.com
7
Pendulum Clock A swinging pendulum has a fixed time between swings. This property can be designed to keep very accurate time. A clever ‘escapement’ mechanism converts swinging motion to rotation motion AD Build-It-Yourself.com
8
Electric Clock Electric motors eliminated the need for frequent resetting of previous clocks AD Build-It-Yourself.com
9
Atomic Clock As scientists required extremely accurate measures of time, the atomic clock was invented. 1955AD This clock can keep time accurate to within Build-It-Yourself.com
