This alarm clock uses scent cartridges to wake you up to the smell of your favorite things, from bacon (!!!) to sweet peach. You can purchase any variety of cartridges you'd like (scents include bacon, cappuccino, mint, strawberry candy, banana, and sweet peach), but your initial purchase will come with one bacon capsule. Each cartridge contains 30 wake-ups.
This Mission style wall clock is finished in a Mission Oak dark finish. A parchment dial features dark brown numerals and hands. Decorative, wooden moldings frame the dial. Circular brushed brass swinging pendulum is antiqued and framed with wooden, reeded grilles. Quartz, dual chime movement plays Westminster or Ave Maria chimes, and features volume control and automatic nighttime shut-off option. Shadow collection - matching floor clock available. Size: H. 32-1/2" W.16-3/4" D.6"
Its display can be turned off or dimmed, so the large, easy-to-read numbers won’t blind you all night long. If you like to wake up to the radio or to an alarm that gets louder over time, you won’t find those features here (though there is a version with a Bluetooth speaker but still no radio). Still, it does its job well, and there’s a reason this clock is found in lots of hotel rooms.
A. Like many items today, the amount you’ll pay for an alarm clock depends on how much technology you want layered onto it. If you desire nothing but a simple analog alarm clock that rouses you with a single tone, you could spend as little as $10. A slightly more sophisticated clock radio might cost $20 or so. If you want a deluxe digital alarm clock with screen projection, Bluetooth capability, MP3 player, or other cool features, you’re looking at a price of anywhere from $40 to $90.
If the four alarms you scheduled to go off 10 minutes apart wake your neighbors but not you, you might want to try this noisy clock; it has a 113-decibel alarm—about as loud as a jackhammer. And if the volume alone won't do it, the red flashing lights and accompanying bed-shaker unit (which goes beneath your mattress) should deliver the full sensory message that grave danger awaits unless you get out of bed.
Pairing a simple design with a contrasting black-and-silver palette, this eye-catching 12" wall clock instantly elevates your favorite aesthetic. Its round silhouette blends effortlessly into both casual or formal spaces, while its clean profile adds sophistication to your decor.

Most digital computers depend on an internal signal at constant frequency to synchronize processing; this is referred to as a clock signal. (A few research projects are developing CPUs based on asynchronous circuits.) Some equipment, including computers, also maintains time and date for use as required; this is referred to as time-of-day clock, and is distinct from the system clock signal, although possibly based on counting its cycles.


Place Sense by Hello on your bedside table, and it will help you fall asleep, stay asleep, and wake up without the grogginess or fatigue you may be used to. The small, white orb plays ambient noises to help ease you into dreamland, and a small monitor clipped to your pillow tracks your movements throughout the night, and sends feedback to an app on your smartphone. By monitoring your sleep cycles, the alarm knows the best time to wake you up in the morning so you're feeling refreshed.
But where OK to Wake! really shines (pun intended) is in its unique feature that parents love; the clock will glow green and show a cute face when it's an acceptable time for your little one to get out of bed. That means even very young children can learn when it's okay to go looking for mommy or daddy — no need to be able to actually read the time. As your child grows, you can stop using the glow feature, and simply use the device as a regular, albeit cuter than average, alarm clock.
Clockmakers developed their art in various ways. Building smaller clocks was a technical challenge, as was improving accuracy and reliability. Clocks could be impressive showpieces to demonstrate skilled craftsmanship, or less expensive, mass-produced items for domestic use. The escapement in particular was an important factor affecting the clock's accuracy, so many different mechanisms were tried.
Certainly not just for telling time, wall clocks are perfect for adding artful appeal to your kitchen wall or acting as a focal point above the living room mantel.

This product requires one AA battery to operate, which is not included. The manufacturer for this item provides a limited one-year warranty.

For convenience, distance, telephony or blindness, auditory clocks present the time as sounds. The sound is either spoken natural language, (e.g. "The time is twelve thirty-five"), or as auditory codes (e.g. number of sequential bell rings on the hour represents the number of the hour like the bell, Big Ben). Most telecommunication companies also provide a speaking clock service as well.

Some clocks, usually digital ones, include an optical projector that shines a magnified image of the time display onto a screen or onto a surface such as an indoor ceiling or wall. The digits are large enough to be easily read, without using glasses, by persons with moderately imperfect vision, so the clocks are convenient for use in their bedrooms. Usually, the timekeeping circuitry has a battery as a backup source for an uninterrupted power supply to keep the clock on time, while the projection light only works when the unit is connected to an A.C. supply. Completely battery-powered portable versions resembling flashlights are also available.

Although the mechanisms they use vary, all oscillating clocks, mechanical, digital and atomic, work similarly and can be divided into analogous parts.[64][65][66] They consist of an object that repeats the same motion over and over again, an oscillator, with a precisely constant time interval between each repetition, or 'beat'. Attached to the oscillator is a controller device, which sustains the oscillator's motion by replacing the energy it loses to friction, and converts its oscillations into a series of pulses. The pulses are then counted by some type of counter, and the number of counts is converted into convenient units, usually seconds, minutes, hours, etc. Finally some kind of indicator displays the result in human readable form.
late 14c., clokke, originally "clock with bells," probably from Middle Dutch clocke (Dutch klok) "a clock," from Old North French cloque (Old French cloke, Modern French cloche), from Medieval Latin (7c.) clocca "bell," probably from Celtic (cf. Old Irish clocc, Welsh cloch, Manx clagg "a bell") and spread by Irish missionaries (unless the Celtic words are from Latin); ultimately of imitative origin.

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,[68][69] or quality factor, which increases (other things being equal) with its resonant frequency.[70] 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.


Some clocks, usually digital ones, include an optical projector that shines a magnified image of the time display onto a screen or onto a surface such as an indoor ceiling or wall. The digits are large enough to be easily read, without using glasses, by persons with moderately imperfect vision, so the clocks are convenient for use in their bedrooms.

In mechanical clocks this is done mechanically by a gear train, known as the wheel train. The gear train also has a second function; to transmit mechanical power from the power source to run the oscillator. There is a friction coupling called the 'cannon pinion' between the gears driving the hands and the rest of the clock, allowing the hands to be turned to set the time.[73]
The ancient Greek philosopher Plato (428–348 BC) was said to possess a large water clock with an unspecified alarm signal similar to the sound of a water organ; he used it at night, possibly for signaling the beginning of his lectures at dawn (Athenaeus 4.174c).[2] The Hellenistic engineer and inventor Ctesibius (fl. 285–222 BC) fitted his clepsydras with dial and pointer for indicating the time, and added elaborate "alarm systems, which could be made to drop pebbles on a gong, or blow trumpets (by forcing bell-jars down into water and taking the compressed air through a beating reed) at pre-set times" (Vitruv 11.11).[3]

Analog clocks display time with an analog clock face, which consists of a round dial with the numbers 1 through 12, the hours in the day, around the outside. The hours are indicated with an hour hand, which makes two revolutions in a day, while the minutes are indicated by a minute hand, which makes one revolution per hour. In mechanical clocks a gear train drives the hands; in electronic clocks the circuit produces pulses every second which drive a stepper motor and gear train, which move the hands.

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 some scientific work timing of the utmost accuracy is essential. It is also necessary to have a standard of the maximum accuracy against which working clocks can be calibrated. An ideal clock would give the time to unlimited accuracy, but this is not realisable. Many physical processes, in particular including some transitions between atomic energy levels, occur at exceedingly stable frequency; counting cycles of such a process can give a very accurate and consistent time—clocks which work this way are usually called atomic clocks. Such clocks are typically large, very expensive, require a controlled environment, and are far more accurate than required for most purposes; they are typically used in a standards laboratory.

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.
Alarm clocks, like almost all other consumer goods in the United States, ceased production in the spring of 1942, as the factories which made them were converted over to war work during World War II, but they were one of the first consumer items to resume manufacture for civilian use, in November 1944.[13][14] By that time, a critical shortage of alarm clocks had developed due to older clocks wearing out or breaking down. Workers were late for, or missed completely, their scheduled shifts in jobs critical to the war effort.[14] In a pooling arrangement overseen by the Office of Price Administration, several clock companies were allowed to start producing new clocks, some of which were continuations of pre-war designs, and some of which were new designs, thus becoming among the first "postwar" consumer goods to be made, before the war had even ended.[15][16] The price of these "emergency" clocks was, however, still strictly regulated by the Office of Price Administration.[14]
