![]() There was also one major disadvantage of the pendulum clock: it wasn’t portable. Pendulum clocks needed to be wound up regularly to keep the time accurately. Eventually, the clock will slow down and become inaccurate. There are lots of factors that mean that kinetic energy decreases, such as air resistance. Kinetic energy to potential (and vice versa) isn’t transferred perfectly. The issue with pendulums is around accuracy and upkeep. Their predictable pattern can therefore be used to measure time. In other words, a regulated and repeating movement like the swinging of a pendulum. Oscillators cause a repeating back and forth movement of energy. Oscillators are essential to every form of timekeeping, including quartz watches. This mechanism, with energy being transferred continually between potential and kinetic is called a ‘harmonic oscillator’. A pendulum could be designed to swing to the exact time to mark seconds. Energy is repeatedly transferred in order to keep a regular rhythm. The weight then reaches the other side and the process repeats. Due to gravity, potential energy is then transferred into kinetic energy (movement). As it reaches its highest point, it has lots of potential energy. A weight on the end of the pendulum regulates its swinging. Pendulum clocks worked due to the physics of a pendulum’s swing. This was taken up in England in 1670 by a clockmaker called William Clement, who made the first grandfather’s clock. This idea was taken up by a Dutch scientist called Christiaan Huygens and in 1656 he designed and built the first ever pendulum clock. An Italian polymath called Galileo Galilei studied the way a pendulum swung and discovered that it could be used to regulate time in a clock. ![]() Pendulum clocks were the first form of precision timekeeping that were widely used. The earliest known clock dates back to 3rd century BC in ancient Greece, but it’s only around the 15th century AD that precision timekeeping and domestic clocks were first introduced. Many people used sundials, which could have been as simple as a stick in the ground, to keep track, but these were useless without sunshine (which is often the reality in the UK!), and not very precise. When people’s worlds were smaller and they interacted less with those around the world and even around the country, this was enough. For many, this was as simple as getting up when it rose and going to bed when it set. To understand how a quartz watch works, it’s important to understand the way watches worked previously, and therefore the brand new function that quartz brought to the table.įor hundreds of years, people used the sun to approximate time. ![]() It is powered by winding up the watch.Īutomatic movement: Uses kinetic energy from wrist movements to drive the watch’s mechanism. Mechanical movement: The second-hand moves smoothly and continually without ticking. This is powered by a quartz crystal and battery. Quartz movement: The second-hand ‘ticks’ by one second, pauses and ticks the next second. This is in contrast to automatic movement and mechanical. The term ‘quartz movement’ refers to the way the quartz and battery cause the second hand to ‘tick’, marking one second at a time. Since this technology was first invented, quartz watches have dominated the market and are considered the best timekeeping mechanism for any high-end timepiece. Quartz wristwatches come in all sorts of different shapes and designs, and quartz clocks are also available as free-standing or wall clocks. It’s an entirely different system from mechanical or automatic watches and is deemed one of the most accurate. Any watch that uses quartz as part of the mechanism is classed as a quartz watch. ![]() Read more about how a quartz watch works from Mondaine, manufacturers of Swiss watches.Ī quartz watch, or clock, is a timepiece that uses quartz crystal, a battery and an electronic oscillator. While previously watches ran on a tiny and intricate system of gears, quartz introduced a brand new and more accurate way to measure time. Quartz revolutionised the watchmaking industry, turning it upside down in just a few years during the Quartz Revolution. ![]()
