Casio G-Shock GA-100MB – Review and opinion

We can already tell you that this Casio digital analog watch is one of their best sellers… that’s why they have so many models with different colors. And it is a watch that is highly appreciated by both the military and members of the police.

In the case of this model, the design is completely black with green tones on the screens and dials, very camouflage, perfect with a lot of light and not so much with little… unless you’re hiding from someone, then the watch is perfect to go unnoticed.

What doesn’t go unnoticed is its size: It’s quite a big watch at 51mm in diameter, but it doesn’t give that feeling when you put it on.

My wrist is 19cm, so you get the idea. The weight is 70 grams, so you don’t notice that you are wearing it. The mineral glass is fully protected by the edges of the case, and the same is true of the 4 buttons, which are tucked into their recesses. They are somewhat rough. The big fingers will suffer a bit to press them.

And what about the dial design? Very striking, both in this color and in the other versions.

We do not have secondhand (they are shown on the lower right screen next to the day). On the lower left screen, you can see the date. The top two digital dials help you interact with alarms, timers, and more (same as the analog dial).

With good visibility the dial is beautiful. The hands are always quite visible… the screens are not so much when there is little light or when we turn the watch in certain positions (the reflection does not help).

The orange LED light comes out of the bottom…and does what it can to help us tell the time in the dark.

The belt? Good resin manufacturing, double and quite comfortable although somewhat rigid at first. The design is quite striking when put together with the box. It is a 22m leash.

Features? Don’t expect a smartwatch. The typical Casio ones, but well developed in this model.

• World time in 29 time zones, stopwatch, timers, 5 daily alarms, alarm clock, a speed indicator that allows us to measure the average speed of a distance traveled, automatic calendar…

We are going to have to read the instructions to know how they work. You know…a few different button presses.

Endurance? It’s a G-Shock…. Falls below, 100 meters in the water… and the case is built in such a way that the watch mechanism is protected from magnetic fields.

Is the time reliable? Every month it breaks about 15 seconds, so every 4 months you should check it. Stack? It will last 2 years or a little more.

Conclusion

If you are looking for a military watch with a spectacular design, this is the Casio model you were looking for. The visibility of the screen is not very good in low-light situations.

It’s tough, comfortable, and dirt cheap for a G-shock. It would need to have solar charging and Multiband 6… Bluetooth doesn’t have it either, but we can get past this type of connectivity.

In favor:

• Great dial design and color
• Very cheap
• Resistant

Against:

• No solar charging or Multiband 6
• LED light is somewhat poor
• Difficult to read digital displays in low light
