How has the water clock changed over time?

Water clocks, or clepsydras, have evolved significantly since their early use in ancient civilizations. Initially, they relied on the steady flow of water to measure time, often using simple containers. Over the centuries, designs improved with the introduction of more precise mechanisms, such as gears and floats, leading to greater accuracy. Today, while largely obsolete due to modern timekeeping technologies, water clocks are appreciated for their historical significance and craftsmanship.
