Some predecessors to the modern clock may be considered as "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels.[1][2][3][4]

It’s vital to your personal health. When you rest at night, after about twenty to thirty minutes, your body begins to enter REM sleep (if you’re lucky). Either way, your body slows down. Your heart rate hits around 40-50 BPM when you’re sleeping, compared to the 60-100 BPM you go through while you’re awake. This gives your body time to give your heart a rest, repair blood vessels, and repair muscle tissue if you worked out, or physically strained yourself during the day.

In a pendulum clock an escape wheel is allowed to rotate through the pitch of one tooth for each double swing of the pendulum and to transmit an impulse to the pendulum to keep it swinging. An ideal escapement would transmit the impulse without interfering with the free swing, and the impulse should be as uniform as possible. The double three-legged gravity escapement, which achieves the second of these but not the first, was invented by Edmund Beckett, afterward Lord Grimthorpe, and used by him for the great clock at Westminster, now generally known as Big Ben, which was installed in 1859. It became the standard for all really accurate tower clocks.

Until advances in the late twentieth century, navigation depended on the ability to measure latitude and longitude. Latitude can be determined through celestial navigation; the measurement of longitude requires accurate knowledge of time. This need was a major motivation for the development of accurate mechanical clocks. John Harrison created the first highly accurate marine chronometer in the mid-18th century. The Noon gun in Cape Town still fires an accurate signal to allow ships to check their chronometers. Many buildings near major ports used to have (some still do) a large ball mounted on a tower or mast arranged to drop at a pre-determined time, for the same purpose. While satellite navigation systems such as the Global Positioning System (GPS) require unprecedentedly accurate knowledge of time, this is supplied by equipment on the satellites; vehicles no longer need timekeeping equipment.

About 1581 Galileo noticed the characteristic timekeeping property of the pendulum. The Dutch astronomer and physicist Christiaan Huygens was responsible for the practical application of the pendulum as a time controller in clocks from 1656 onward. Huygens’s invention brought about a great increase in the importance and extent of clock making. Clocks, weight-driven and with short pendulums, were encased in wood and made to hang on the wall, but these new eight-day wall clocks had very heavy weights, and many fell off weak plaster walls and were destroyed. The next step was to extend the case to the floor, and the grandfather clock was born. In 1670 the long, or seconds, pendulum was introduced by English clock makers with the anchor escapement.

The origin of the all-mechanical escapement clock is unknown; the first such devices may have been invented and used in monasteries to toll a bell that called the monks to prayers. The first mechanical clocks to which clear references exist were large, weight-driven machines fitted into towers and known today as turret clocks. These early devices struck only the hours and did not have hands or a dial.

Wall clocks are available in a wide array of colors to fit any decor style. Classic black and white, silver or antique metal, and natural, brown, or dark wood choices have timeless appeal. Fun colors like red or turquoise are also available. Most clocks feature a high-contrast face with a white background and black numbers or roman numerals to make seeing the time easier.
Clock radios are powered by AC power from the wall socket. In the event of a power interruption, older electronic digital models used to reset the time to midnight (00:00) and lose alarm settings. This would cause failure to trigger the alarm even if the power is restored. To solve this issue, they trigger the alarm at 00:01 after a reset, so that at least the user is able to correct the clock and alarm settings. Most of the recent clock radios use a battery backup to maintain the time and alarm settings. Some advanced radio clocks (not to be confused with clocks with AM/FM radios) have a feature which sets the time automatically using signals from atomic clock-synced time signal radio stations such as WWV, making the clock accurate and immune to time reset due to power interruptions.

For light sleepers, audio alarms can be rather jarring. Fortunately, the Philips Morning Wake-Up Light uses a warm, gentle glow and natural sound effects rather than incessant beeping to get you out of bed. The alarm clock also features a colored sunrise simulation and 20 brightness settings for optimal customization. The light slowly increases in brightness between 20 and 40 minutes prior to your desired alarm time. The clock helps you drift to sleep, too. Instead of you simply turning out the lights and settling into bed, the light-responsive dimming feature gently guides you to sleep with audio accompaniment. This type of alarm is definitely not for everyone, but it is suitable for those who prefer to wake up gradually. For more details, read our full Philips Wake-Up Light review.
