What Is Tough Solar G Shock? How Does It Work?

Casio’s G Shock series is not only one of the most famous watch lines in the timepiece industry, but it’s also among the most durable. In addition, all G-Shock models include an excellent innovation named “Touch Solar system.” So, what is Touch Solar G-Shock technology anyway?

What Is Tough Solar G-Shock?

Overall, it means light energy is used for the Sun’s power watches. In other words, the light is “caught” by the panels, which turn it into power. 

The CASIO Tough Solar System has progressed to the point that even the most minor light beams are enough to power your timepieces.

How Does Casio Tough Solar Work?

The power of sunlight is responsible for running watches. They are designed with panels to capture light and convert it into energy that powers the whole system. 

The Casio Tough System has progressed to the point that it can run efficiently using natural and artificial illumination, even secondary light sources. 

They employ tiny, unobtrusive solar cells that can be readily incorporated into the design of watch faces, aided by the fact that the panel may be produced in any color and pattern. 

An accumulation is a clever piece of technology included in each Casio solar watch. Whenever it is in darkness, the accumulator’s function is to store surplus energy and release it as required. These charge themselves and do not require any manual reactivity from you.

You can rely on this video to better understand how the system on Casio G-Shock works.

Are Casio Tough Solar Watches Good?

Yes, Casio’s Tough watches are excellent for all of the following reasons.

First, these models are available in a wide selection of shapes and styles to fit any budget. Besides, the concept of a Sun’s-powered timepiece is terrific since they remove the need for battery replacement, saving money and time. Additionally, saving energy can be a more environmentally friendly option that many people opt for.

How Long Do The Casio Solar G-Shock Batteries Last?

Although with all the bells and whistles, the minimum lifespan of a Shock solar watch is roughly 10 years. You may easily extend it to approximately 20 years if you do not expect to utilize the tens of additional functions they come with nowadays.

 The batteries in these timepieces are rechargeable, which is the key to their lengthy lifespan. Each time a Casio product with solar battery technology is exposed to sunshine, it is recharged. 

As said, the sun’s energy is received by a panel, which then transforms it to electric power to charge the battery. As a result, G-Shock Solar watches are frequently more costly than others using conventional batteries. 

They do, of course, have certain benefits over traditional wristwatches. For instance, they are indeed environmentally friendly. Also, every G-Shock Tough model will require very little maintenance, which means you won’t have to worry about the battery changes.

How To Prolong Your Tough Solar G-Shock Watch’s Battery Life?

1. The battery is charged when it is exposed to light on a regular basis

Even when not exposed to light, a Sun’s-powered watch continues to function. Leaving it in the dark might drain the battery and inhibit some features. 

2. Excessive use of the display light should be avoided

Here is how much light exposure is necessary to charge a battery for one display light run. 

  • Exposure to solid sunshine streaming in via a window for around 5 minutes 
  • Absorption to indoor fluorescent lights for about 50 minutes 

More caution is necessary when utilizing the Auto Light option (possible on some watches), resulting in repeated display lighting.

3. Suggestions for keeping the battery charged

  • The watch type determines the battery power indicator’s level. 
  • When you’re not wearing your ticker, please spend a few seconds repositioning it so that the face is facing a vital light source. Place the watch near the window or under fluorescents. 
  • If you’re wearing it, make sure your sleeve isn’t obstructing the solar panel on the face. Although the watch face is only partly covered, charging effectiveness is lowered.


After reading this article, you may understand what a Tough Solar G-Shock system is and how it functions. These solar-powered watches are environment-friendly and last you longer than others; therefore, take one if possible. Thanks for reading!
