Atomic Watch Buying Guide

What is an Atomic Watch? 

An atomic watch or atomar watch is a timepiece that is always accurate and doesn’t need to be adjusted. That’s because it connects via a radio frequency to keep it up to date. Sometimes called a radio watch or radio clock, an atomic watch receives a signal from the official U.S. government time via a time calibration signal from the atomic transmitter in Ft. Collins, Colorado. 

The signal will travel over 1800 miles, making atomic watches that connect in the United States somewhat limited in areas such as Alaska or Hawaii. Once outside of the signal area, the watch still functions but can’t be updated until back in the signal area, and may not be able to account for changing time zones, for instance. However, some watches have the capacity to connect to atomic signals in Europe, the United Kingdom, Japan and more.

Atomic watches never need to be adjusted for factors such as Daylight Savings Time, Leap Years, or discrepancies between months. That makes atomic timekeeping watches a desirable addition to the wardrobe of those who prefer – or demand – accuracy.

Most atomic timekeeping watches will automatically update at night. Many atomic watches also have the option for the user to check when it last synchronized, the status of the signal reception strength, or have the ability to manually synchronize.  


When searching for an atomic clock watch, the type of watch is a personal preference. You can choose from an analog or digital style, and you can find watches that run on solar power or battery power.

Atomic Analog Watch

Those who want a dressy look to their watch will often choose an analog watch, although analog watches can also have a sporty look. Analog watches sometimes have extra features like chronograph displays, and some have a small digital display as well as the main analog display.

Atomic Digital Watch

An atomic digital watch will often have more features, or “bells and whistles” than an analog watch. Some are made for fitness enthusiasts, with lap display, timers and alarms. Some have world clocks from various cities. The features you want on your atomic digital watch will dictate your final choice.

Solar Atomic Watch

Atomic watches can be either battery-powered or solar powered. If you have a battery-powered watch, and you have to change the battery, the watch won’t be able to set the time until it receives the atomic signal. That usually happens at night, when radio interference is lowest. 

Atomic watches can also have special power functions, such as the Citizen Eco-drive technology. The Eco-Drive watch is fueled by any kind of light and never needs a battery.


Choosing the design of an atomic watch is a personal one. They can range from sporty, digital, watches to sleek, dressy analog watches. They can feature different types of displays, from a busy watch face to a minimalist design. Watch bands also vary, from resin to leather to stainless steel or stainless steel plated. The design of atomic clock watches is as varied as any other type of watch.


How you’ll use your atomic watch will dictate the durability of the construction that you need. Sports watches tend to be a bit more durable, so that you can use them cycling, running or hiking. Dress watches are better used in an office setting.

Our Verdict

Atomic clock watches are made by several reputable watch companies, and the style, design and features are as varied as the companies themselves. If you’re looking for a watch that will always provide you with an accurate time, and never has to be updated for Daylight Savings Time, Leap Years and more, you want an atomic watch. These are the most accurate timepieces you can find.

The atomar watch keeps such accurate time because it connects via a signal from a central unit. Its radio-controlled synchronizing means you never have to worry about your atomic timekeeping watch being a few minutes off. You’ll never have to reset it. And if you choose the right one, you can travel with it and pick up various signals.

The final choice among our top picks is among an analog vs. digital style, the type of power for the watch, and for some the look of the watch itself. Women tend to like a smaller timepiece, and athletes may want more features on their watch.

Whatever your final pick, you can’t go wrong with one of our atomic watch selections.
