Marathon's Atomic alarm clock with temperature and date is packed with features. It has an ambient light sensor, which allows the auto-night light to illuminate the display when necessary. With a soft amber LED, the large digit display is easy to read at night and becomes even brighter if the Snooze/Light button is pressed. At a glance you can easily see the time, date, day and temperature. The controls on the front of the clock allow you to easily set the alarm, switch between Fahrenheit or...
While it’s not to be used in lieu of an alarm clock, this handy app will aggravate the hell out of you until you’re awake.

You can set the clock to release aromatherapeutic scents in tandem with the light, choosing from four different fragrances that come with the clock or using your own essential oil blend.

The geometric pattern will stand out against any color wall, while the golden finish adds a pop of glamorous appeal. At the center is a golden disk with two sleek black hands.

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.

Windsor Cherry finished wood columns provide a warm accent on each side. Convex glass covers the antique dial, which offers black Roman numerals and serpentine hands. The swinging pendulum is finished in warm gray with dusty wax highlights to match the case. Quartz, non-chiming battery operated movement.
Electric currents can be used to replace the weight or spring as a source of power and as a means of signaling time indications from a central master clock to a wide range of distant indicating dials. Invented in 1840, the first battery electric clock was driven by a spring and pendulum and employed an electrical impulse to operate a number of dials. Considerable experimental work followed, and it was not until 1906 that the first self-contained battery-driven clock was invented.
While some people have a type of internal clock and can wake up around the same time every day, most people need a little extra help in this department. Without an alarm clock, you could sleep through your plans for the day, whether those plans include fun activities with loved ones or getting things done around the house. You might think you can use the built-in alarm on your phone. However, it's too easy to grab your phone from your bedside table and turn off the alarm without really waking up and getting going for the day.
A clock radio is an alarm clock and radio receiver integrated in one device. The clock may turn on the radio at a designated time to wake the user, and may also include a buzzer. Typically, they are placed on the bedside stand. Some models offer dual alarm and "snooze", a large button on the top that stops the alarm and sets it to ring again a few minutes later.[18] Some clock radios also have a "sleep" timer, which turns the music from radio on for a set amount of time (usually around one hour). This is useful for people who like to fall asleep with the radio on.
Now this is an alarm clock for the heaviest sleeper. If you're the type who sleeps through anything — thunderstorms, loud neighbors, earthquakes, the zombie apocalypse — you've finally met your match. Sonic Alert's Sonic Bomb Alarm Clock doesn't just rely on its 113-decibel alarm to pry your eyelids open (for comparison, that's about the same decibel level as a car horn or snow blower going off in your ear), it also has a shaker device that slips underneath your mattress or pillow to jiggle you awake, and red flashing lights that trigger with the alarm.
“Great alarm clock for the price. Gigantic numbers for my old eyes. Very basic, easy to set, just what I wanted. Alarm is loud even on low [with] an awful sound that would wake the dead. But that sound makes me get right up, so it does exactly what it’s supposed to do. If you want a soft gentle caress to wake you, get something else, but this is a good alarm and easy to use.”
