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.[54] Atomic clocks were first theorized by Lord Kelvin in 1879.[55] In the 1930s the development of Magnetic resonance created practical method for doing this.[56] 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.[57][58][59] 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.[60] Calibration of the caesium standard atomic clock was carried out by the use of the astronomical time scale ephemeris time (ET).[61] 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).[62]

In Europe, between 1280 and 1320, there is an increase in the number of references to clocks and horologes in church records, and this probably indicates that a new type of clock mechanism had been devised. Existing clock mechanisms that used water power were being adapted to take their driving power from falling weights. This power was controlled by some form of oscillating mechanism, probably derived from existing bell-ringing or alarm devices. This controlled release of power—the escapement—marks the beginning of the true mechanical clock, which differed from the previously mentioned cogwheel clocks. Verge escapement mechanism derived in the surge of true mechanical clocks, which didn't need any kind of fluid power, like water or mercury, to work.

Although it isn’t strictly an “alarm clock,” the Google Home Hub can wake you up in the morning and do so much more. One of the most drastic differences between the Home Hub and other comparable devices is its size; the Home Hub stands at a mere 4.5 inches tall. This makes it small enough to fit comfortably on a nightstand. That small frame is partly due to the lack of a camera, which may be a pro or a con depending on how much you value your privacy. The Home Hub connects to the various Bluetooth-enabled devices you might have throughout your home, including lights, speakers, thermostat, etc. You can set up the Home Hub to respond to your voice commands, or manage devices using the touchscreen. For the purposes of an alarm clock, the Home Hub works terrifically. You can set a normal alarm, or even have the Hub wake you with a specific song from your music library. Given the Hub’s lackluster built-in speakers, however, you may want to connect it to your sound system if you have one. For more details, read our full review.

Traditional mechanical alarm clocks have one or two bells that ring by means of a mainspring that powers a gear to propel a hammer back and forth between the two bells or between the interior sides of a single bell. In some models, the back encasement of the clock itself acts as the bell. In an electric bell-style alarm clock, the bell is rung by an electromagnetic circuit and armature that turns the circuit on and off repeatedly.[1]
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,[31] and some 15th-century clocks in Germany indicated minutes and seconds.[32] An early record of a seconds hand on a clock dates back to about 1560 on a clock now in the Fremersdorf collection.[33]:417–418[34]

Many devices can be used to mark passage of time without respect to reference time (time of day, minutes, etc.) and can be useful for measuring duration or intervals. Examples of such duration timers are candle clocks, incense clocks and the hourglass. Both the candle clock and the incense clock work on the same principle wherein the consumption of resources is more or less constant allowing reasonably precise and repeatable estimates of time passages. In the hourglass, fine sand pouring through a tiny hole at a constant rate indicates an arbitrary, predetermined, passage of time. The resource is not consumed but re-used.
The clock features a solid wood core and wooden mini balls finished in rich brown tones. There are numerous silver rods radiating out from the core with some bearing wooden balls and others not.

Health chose the Sonic Bomb as one of the best alarm clocks for heavy sleepers, commenting that the flashing lights, loud sound, and bed shaker should "deliver the full sensory message that grave danger awaits unless you get out of bed."

Still, they say, "It won us over with how effective and customizable it is."

Plus, the clock has dual alarms, so both you and your partner can have different wake-up times.
In 1735, Harrison built his first chronometer, which he steadily improved on over the next thirty years before submitting it for examination. The clock had many innovations, including the use of bearings to reduce friction, weighted balances to compensate for the ship's pitch and roll in the sea and the use of two different metals to reduce the problem of expansion from heat. The chronometer was tested in 1761 by Harrison's son and by the end of 10 weeks the clock was in error by less than 5 seconds.[43]
