How Accurate Are Casio Watches? (Explained In Detail)

Several decades since its first launch, Casio has obtained impressive popularity, establishing itself as one of the most well-known watch brands worldwide.

In addition to the affordable prices, their products have won many people’s hearts due to their accuracy and reliability.

Yet, you may also come across some complaints on the internet about how some of these timepieces function inefficiently.

So, how accurate are Casio watches? Are they truly worth the price?

Check out the detailed answer in this article to make an informed decision.

How Accurate Are Casio Watches Exactly? 

According to the Casio manual, though the actual number depends on each model design and component, most of this brand’s battery-powered watches may lose or gain from 15 to 20 seconds per month.

In other words, each day, these watches illustrate a 0.5- or 0.6- second difference from the accurate time.  

Apparently, you may not realize how your watch falls behind or goes ahead of the atomic clock time with such a minor difference.

Also, at that rate, it takes at least 15 months for your clock to be off by 5 minutes.

Thus, Casio timepieces are usually evaluated to be both accurate and reliable. 

Nevertheless, it is crucial to suggest that the accuracy varies among distinguished models.

So keep reading to figure it out.

Casio Watch Accuracy Chart 

Since each model is built with a specific movement, it is reasonable that these timepieces may demonstrate some differences in their accuracy.

Explore the accurate chart below to gain a further understanding of each model’s performance. 

Model Measurement

(how many times it was measured)


(on average per day)

Casio Royale 11 measurements
  • 0.13 seconds
MDV – 106 Duro 19 measurements
  • 0.19 seconds
MDV – 106 Duro Blue 7 measurements
  • 0.11 seconds 
W-736H Super Illuminator 3 measurements
  • 0.12 seconds
G-Shock G-011D Cube 15 measurements
  • 0.32 seconds
G-Shock 5600 NASA21 3 measurements
  • 0.13 seconds
G-Shock DW-5600BB 12 measurements
  • 0.22 seconds
G-Shock DW5735D-1B 15 measurements
  • 0.27 seconds
G-Shock GA800 13 measurements
  • 0.22 seconds
G-Shock GA900 13 measurements
  • 0.31 seconds

As can be seen, the real-life test has proved Casio’s quality.

Most models perform better than the brand’s accurate claim.

For example, the MDV-106 Duro Blue only gains 0.11 seconds per day, equivalent to 3.3 seconds monthly.  

Why Do Casio Watches Usually Have Impressive Accuracy? 

Entering the watchmaking market in 1974, Casio has developed and manufactured watches for almost half a century.

Such a long history allows them to research and implement several great technologies for these watches accuracy models. 

For example, the G-Shock and Wave Ceptor product lines adopt Multiband 6 Radio technology.

This feature allows these watches to receive direct signals from various transmission stations around the world. 

Thus, the time they display is pretty similar to an atomic clock, thus being remarkably accurate.

Also, the GPS Hybrid Technology and energy-efficient GPS utilized in many other models enable Casio watches to show accurate time no matter which time zones you are in. 

How Accurate Is Casio Altimeter?

If you are an adventurer who loves to explore high, mountainous areas, an altimeter is one of the parameters you pay the most attention to.

Understanding this concern, the brand has equipped its Casio Pro Trek product line with Triple Sensor Technology, which measures altitude, temperature, and direction.  

Consequently, the Pro Trek watches will detect the air pressure changes when you move from one location to another.

After that, it would be able to determine the altimeter for display.

Thus, with this design, experts have strongly agreed on the Pro Trek is accurate. 

How accurate is Casio’s digital watch?

Casio’s digital watches are generally accurate within 0,5 seconds per day, which is comparable to the accuracy of most quartz analog watches.

If you want the most accurate timekeeping, you might want to consider a radio-controlled watch, which synchronizes its time with an atomic clock.

Casio also makes some models of radio-controlled watches.

How accurate is Casio quartz?

Casio quartz watches are accurate within a margin of error of 1/2 second per day.

This is on par with the accuracy of most other quartz analog watches.

For the most accurate timekeeping, you may want to consider a radio-controlled watch instead.

How accurate is a Casio Wave Ceptor?

A Casio Wave Ceptor watch is accurate to within 0,5 seconds per day.

This level of accuracy is on par with most other quartz analog watches.

If you want the most accurate timekeeping, you may want to consider a radio-controlled watch instead.

These watches sync their time with an atomic clock for unbeatable accuracy.

What is the most accurate wristwatch?

The most accurate wristwatch is generally a radio-controlled watch, which synchronizes its time with an atomic clock.

Casio makes some models of radio-controlled watches.

How do I know if my watch is accurate?

The easiest way to determine if your watch is accurate is to compare it to the time on another device, such as a clock or your phone.

If the time on your watch is different from the time on the other device, then your watch is not accurate.

You can also use an online stopwatch or timer to check the accuracy of your watch.

Start the stopwatch or timer on your watch and compare it to the time on the other device.

If they match, then your watch is accurate.

If they don’t match, then your watch is not accurate.

Are analog watches accurate?

Analog watches can be accurate, but they are not as accurate as digital watches.

Analog watches are affected by factors such as the tension of the spring, the balance wheel, and the escapement.

These factors can cause the watch to gain or lose time.

Digital watches are not affected by these factors and are thus more accurate.

What is the most accurate watch brand?

There is no one “most accurate” watch brand.

Different brands use different technologies to achieve different levels of accuracy.

Some brands are more accurate than others, but there is no definitive answer as to which brand is the most accurate.

How can I make my watch more accurate?

If your watch is not as accurate as you would like, there are a few things you can do to try to improve its accuracy.

  • Make sure the watch is clean and free of dirt and debris. A dirty watch can affect its accuracy.
  • Make sure the watch is wound properly. If the watch is not wound tightly enough, it will lose time.
  • Make sure the watch is not exposed to extreme temperatures. Extreme temperatures can affect the accuracy of a watch.
  • Take the watch to a professional to have it serviced. A professional can clean and adjust the watch to help improve its accuracy.

Final Thoughts

To sum up, it is crucial to suggest that Casio watches are impressively accurate and reliable.

Therefore, you can be assured to purchase one Casio product and wear it as long as you hope for.
