Best Atomic Clock: Top 5 with Alarm, Weather Control, & More

“What’s the time?” Someone asks you this, and where do you look first? You’ve got your watch, your clock, your phone (definitely!), and even advanced refrigerators display time now. 

But really, how accurate are these sources? This is where an atomic clock comes in to save your life. 

A sound option that is always reliable and always accurate. This is especially true if you have a lifestyle that requires you to be always punctual and dependable. Plus, in case of emergencies and all technology fails (like a blackout), your atomic clock will make a difference for you.

I don’t know about you, but our phones have become central to our everyday needs. Whether we need a calculator, a flashlight, a camera, to check the weather, and of course, to check the time. However, as I’ve said, if the power goes out for a long time and all your phones are not charged, where can you look to check the time? Or when the power is restored, how do we know what time to set? 

Even though some prominent physicists will argue that time doesn’t exist, it’s still one of the widely accepted concepts amongst us, humans. And if being precise means something to you, atomic clocks are your answer. And they actually also have a lot of functions and styles. It really depends on how you want to use it. 

If you are in a hurry and looking for a great value atomic clock option that will do the job and won’t break the bank, I’d suggest looking at this device by WallerGe. 

Otherwise, keep reading – I’ve spent quite some time researching for the best atomic clocks that will work for various tasks, and I feel that you might find the list below useful.

Shopping for Atomic Clock. FAQ Section

What is an atomic clock?

An Atomic Clock is a clock that uses specific frequencies of atoms to give extremely accurate time. They are the most precise time standards used for international time distribution.

How do atomic clocks work?

Clocks need an oscillator, a movement between two entities, that keeps track of time. An atomic clock’s oscillator is between the nucleus of an atom and the electrons around it. Hence, atomic oscillations have a higher frequency and are more stable. The process of this is very extensive.

Difference between atomic and other types of clock?

All clocks have some type of “ticker,” an oscillator, a periodic movement/variation between two entities, created by a change in energy. For example, in a grandfather clock, there is a pendulum that sways back and forth. Time is kept due to the swing of the pendulum. But this is not always accurate due to many variables.

The ticker, or oscillations, are from the power line or a quartz crystal in a digital clock. On the other hand, the atomic clock uses the atoms as its oscillator and will vibrate at that frequency. The ticker there is a microwave signal synchronized to atoms’ resonance (more specifically, the resonance of cesium 133 atoms).

Pros and cons of an atomic clock

Pros

  • A remarkably consistent way of telling time
  • Can be used even when the power/technology does not work
  • It can display day, date, weather, temperature, humidity
  • Clear display and comes in various designs

Cons

  • Not all regions in the world have “time signal stations,” and consumer products won’t work as good in these regions
  • The time it takes for a signal to reach the clock may vary
  • Some consumer atomic clocks have a quartz crystal as an oscillator (used in between the time it synchronizes with a time signal station), and this may not be completely accurate

What’s the average price of the device?

The price of the smallest, most accurate atomic clock that is developed by researchers is $1,500. However, the appliances you see online are far more affordable! The average price from the sources mentioned above is $35.
