Early clock dials did not indicate minutes and seconds. A clock with a dial indicating minutes was illustrated in a 1475 manuscript by Paulus Almanus, and some 15th-century clocks in Germany indicated minutes and seconds. An early record of a seconds hand on a clock dates back to about 1560 on a clock now in the Fremersdorf collection.:417–418
As of the 2010s, atomic clocks are the most accurate clocks in existence. They are considerably more accurate than quartz clocks as they can be accurate to within a few seconds over thousands of years. Atomic clocks were first theorized by Lord Kelvin in 1879. In the 1930s the development of Magnetic resonance created practical method for doing this. A prototype ammonia maser device was built in 1949 at the U.S. National Bureau of Standards (NBS, now NIST). Although it was less accurate than existing quartz clocks, it served to demonstrate the concept. The first accurate atomic clock, a caesium standard based on a certain transition of the caesium-133 atom, was built by Louis Essen in 1955 at the National Physical Laboratory in the UK. Calibration of the caesium standard atomic clock was carried out by the use of the astronomical time scale ephemeris time (ET). As of 2013, the most stable atomic clocks are ytterbium clocks, which are stable to within less than two parts in 1 quintillion (2×10−18).

Water clocks, also known as clepsydrae (sg: clepsydra), along with the sundials, are possibly the oldest time-measuring instruments, with the only exceptions being the vertical gnomon and the day counting tally stick. Given their great antiquity, where and when they first existed is not known and perhaps unknowable. 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 BC. Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less certain. Some authors, however, write about water clocks appearing as early as 4000 BC in these regions of the world.
To truly earn its place on your nightstand, an alarm clock should be reliable and versatile, letting you customize your wake-up experience without letting you down.

Thanks to its backup battery, you won’t have a Home Alone oversleeping situation when you need to get to the airport or the power goes out. There’s a big snooze button for those mornings when you need some extra Zs.
The first precise timekeeping mechanism, whose principles of motion were discovered by Galileo, was the simple pendulum (see below). The accuracy of modern timekeeping has been improved dramatically by the introduction of tiny quartz crystals, whose harmonic oscillations generate electrical signals that may be incorporated into miniaturized circuits…
Greek astronomer Andronicus of Cyrrhus supervised the construction of the Tower of the Winds in Athens in the 1st century B.C. The Greek and Roman civilizations are credited for initially advancing water clock design to include complex gearing, which was connected to fanciful automata and also resulted in improved accuracy. These advances were passed on through Byzantium and Islamic times, eventually making their way back to Europe. Independently, the Chinese developed their own advanced water clocks（水鐘）in 725 A.D., passing their ideas on to Korea and Japan.
Molded by mid-century modern style, this 38" wall clock brings a bit of bold flair to any space in your home. Its generous size helps it grab glances (and compliments!) from guests, while its open and numberless design gives it a minimalist feel. Crafted from metal, this round silhouette sports a gold finish with silver-finished hands in the center for subtle contrast. Two AA batteries (not included) are required to operate.
A: From personal experience, a firsthand account of an insomniac, if you will, Sleep Sense really did the trick. There’s a million reasons why you might not be sleeping, and while most of the time it’s stress or something of the sort, it could also be a deficiency of certain vitamins and minerals. Sleep Sense comes with melatonin, magnesium, and other ingredients, all designed to help you sleep, without the fear of becoming addicted or dependent on them. It took about three years to get over insomnia (if the TV is on, I still can’t sleep), but after enough trial and error, and a good dose of Sleep Sense, it did the trick. I stopped dreading the alarm clock so much.
If the only thing that will get you out the door in the morning is some serious nagging, Clockman is for you. This chatty clock refuses to shut up, even after you get out of bed. He'll greet you at your desired time, sing while you get dressed, and even yell if you anger him. While Clockman speaks only Japanese for now, his wake-up-and-get-going message isn't lost in translation.
A: This is difficult because it works differently for everyone involved. If you’re just not able to wake up properly, then you’re probably what most of us are: tired from the constant stress of life and trying to sleep it off to a healthy level. It’s exhausting, all of life. Waking up faster and feeling fuller right when you hit the ground is a must, and it’s difficult. Here’s what to do:
If you’re looking for a calmer start to your day, you might want to try the Wake-Up Light. It gradually gets you up and out of bed with a colored sunrise simulation and a selection of nature-inspired sounds, so that you can start the day feeling refreshed and energized—as if you had woken up naturally. For anyone who finds it particularly hard to get out of bed when it’s cold and dark out, this alarm clock makes those winter mornings that little bit easier. It also comes with a nighttime dimming feature so that you can make sure you’re getting your best night’s rest.
If you've moved away from using a clock completely and instead set an alarm on your phone, consider the SmartShaker by iLuv. The device slides under your pillow and shakes you awake when your phone alarm goes off (it connects wirelessly using bluetooth). You can also have the device sound an audible alarm. The battery lasts a full month before needing to be charged.
The next development in accuracy occurred after 1656 with the invention of the pendulum clock. Galileo had the idea to use a swinging bob to regulate the motion of a time-telling device earlier in the 17th century. Christiaan Huygens, however, is usually credited as the inventor. He determined the mathematical formula that related pendulum length to time (about 99.4 cm or 39.1 inches for the one second movement) and had the first pendulum-driven clock made. The first model clock was built in 1657 in the Hague, but it was in England that the idea was taken up. The longcase clock (also known as the grandfather clock) was created to house the pendulum and works by the English clockmaker William Clement in 1670 or 1671. It was also at this time that clock cases began to be made of wood and clock faces to utilize enamel as well as hand-painted ceramics.

Special features beyond simply keeping time can be either practical or decorative. Often found in the kitchen or other busy room, some digital clocks can show readings of the indoor or outdoor temperature, display the date, and have the capacity to set an alarm or timer. A swinging pendulum is most commonly found on fancier wood and metal clocks, though some novelty styles also feature a pendulum.
The advantage of a harmonic oscillator over other forms of oscillator is that it employs resonance to vibrate at a precise natural resonant frequency or 'beat' dependent only on its physical characteristics, and resists vibrating at other rates. The possible precision achievable by a harmonic oscillator is measured by a parameter called its Q, or quality factor, which increases (other things being equal) with its resonant frequency. This is why there has been a long term trend toward higher frequency oscillators in clocks. Balance wheels and pendulums always include a means of adjusting the rate of the timepiece. Quartz timepieces sometimes include a rate screw that adjusts a capacitor for that purpose. Atomic clocks are primary standards, and their rate cannot be adjusted.
The Philips Wake-Up Light offers a choice of five pleasant nature sounds — or for the more traditionally minded, FM radio — for your morning wake-up call, but the real star of the show is the sunlight simulation. Twenty to forty minutes before your programmed wake-up time (you set both times), the clock will slowly begin to simulate the sunrise, complete with the softest dawn reds and oranges gently brightening into sunny, yellow light.

“Great little dual alarm clock. Super easy to set the two alarms. Easy to use. It has a night light feature with adjustable dimmer, which is great. You can adjust the display completely dark so you don’t see the numbers. Then you can just hit the snooze button when the alarm is not ringing and the display lights up. It’s powered only by 3 AA batteries: no electric cord, no USB, nothing that you need. If you need a fancy alarm clock that sprays water in your face, this is not it.”
