Image result for water clock

Around 325 BC, water clocks began to be used by the Greeks, who called this device the clepsydra ('water thief'). Water clocks are one of the oldest time-measuring instruments.The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon and in Egypt around the 16th century BCE. Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less certain.
