“I was looking for a small, battery-operated clock with a light for my bedside. I wake often in the middle of the night, and I do not keep my cell phone beside the bed (bad idea, as it is tempting to use it, and that does not help sleep). I had a small battery-operated clock I purchased from Walmart years ago, and it finally broke after being knocked off the bedside table too many times. … So I looked on Amazon, and this is the best replacement I could find. It is slightly larger but does the job. I push the top button and can see the time without waking my partner. Nice little clock for the price, and if I knock it off during the night and break it, it has not broken my budget!”
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]

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.
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.

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]
In 1283, a large clock was installed at Dunstable Priory; its location above the rood screen suggests that it was not a water clock.[citation needed] In 1292, Canterbury Cathedral installed a 'great horloge'. Over the next 30 years there are mentions of clocks at a number of ecclesiastical institutions in England, Italy, and France. In 1322, a new clock was installed in Norwich, an expensive replacement for an earlier clock installed in 1273. This had a large (2 metre) astronomical dial with automata and bells. The costs of the installation included the full-time employment of two clockkeepers for two years.[citation needed]
“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.”
