As humans, the need to keep checking our time clocks comes either consciously or unconsciously. It’s inborn in all of us, and we have to keep track of the time whether indoors at home or locked somewhere in an office or even outdoors. While the quartz/standard wall clock works will show indicate the time, it does not offer the precision or accuracy that you get from an atomic wall clock.
A manual clock will require daylight savings time (DST) and the correct time to be adjusted manually. An atomic clock needs you to set your time zone, and it changes the DST and switches to the standard time automatically. Well, accuracy is not the only feature you’ll benefit from using an atomic wall clock. Thermometer and hygrometer are some other properties you’ll find in an atomic wall clock.

An atomic wall clock has a radio housed inside it and receives signals from the location of the atomic clock located at WWVB, Fort Collins, Colorado, US. The radio in the clock will decode the message from WWVB and synchronize it own clock based on that message. Some clocks will decode several times a day while others only decode once. Full details can be found here.
Things to Look for When Purchasing an Atomic Wall Clock
There may not be a straight-forward solution to the requirements of an atomic wall clock. In any case, it cannot be an atomic wall clock if it does not adjust to the standard time and change the Daytime savings during summer automatically.
Aside from those two, there are more properties that every individual brand features that may bring a difference and most likely influence your decision.
Weather Resistance: An atomic wall clock designed for both indoor and outdoor use has all the properties that make it withstand the harsh weather conditions when place outside.
Display: A unit with large digits may be better as you’ll not strain to read from afar
Time Zones: Atomic wall clocks cover several time zones depending on the signal reception. The more time zones, the better you are covered.
Accuracy: We cannot dwell much on the precision of an atomic wall clock as they all synchronize their clocks depending on the signal received from WWVB.
Weather Forecast: Some wall clocks have icons to read the temperature and humidity and their ranges allowing you to predict the weather.
Construction: Apparently, you’ll need to go for an atomic wall clock that looks solid and durable.
Design & Color: Although the appearance does hold much water, sleek design that complements the color of your décor would not be a bad thing.
The market is awash with atomic wall clocks, and we thought you’d go through a great hassle to identify the best. As a result, we’ve prepared detailed reviews of what customers regard as the best clocks to make your shopping easier.
The title provides an insight into the type of clock this is. It’s radio-controlled meaning that it’ll receive frequencies from the NIST station based in Fort Collins, CO. Once the signals have reached the radio housed inside the clock, the message is decoded, and it synchronizes its clock to that of the universal atomic clock. That guarantees you the most accurate date and time to the split second.
Also, it features daylight savings time (DST) which ensures that as the universal atomic clock moves forward by one hour, it also tunes its clock accordingly and automatically. That way, you can enjoy the extended daylight during the months of summer. The best part about it: it allows you to either turn ON/OFF the DST function. That comes in handy for residents of Arizona where DST is not applicable.
What’s more, this clock covers many regions compared to others with only for time zones. You can use it in 6 time zones, P/M/C/E/H/A. For those located outside the time zones, the automatic time and date setting will not occur as there will be no signal or it shall be weak. Fortunately, you can still set the time manually and use the clock.
Besides, it comes with two alarms coupled with a snooze function, AL1 & AL2 making an ideal unit for the bedroom. Even if it’s in the office, you will know when the duration you set has ended. You’ll find it easy to operate the battery. And to stop the alarm going off, any key will do the magic. See also: Top 10 Best Alarm Clocks.
