In-Depth Review of Casio Rangeman GPR-B1000

Size & weight

The Casio G-Shock Rangeman GPR-B1000 is a massive and bulky watch, which should come as no surprise. It measures 57.7mm in diameter and 60.3mm in length. In addition, it has a thickness of 20.2mm. With that being said, it is still relatively light at 142 grams, which allows it to fit more pleasantly on the wrist.


The case has a lot of the classic G-Shock design language, but it also features a lot of changes. First and foremost, the resin “bezel” screwed down to the top of the case is designed with “extensions” on each side to give maximum protection for the pushbuttons as well as the crown at 3 o’clock. 

It’s worth mentioning that the crown doubles as a scroll wheel and pusher, allowing you to move through menu settings.

The case is designed to ensure that this watch can withstand whatever situation you throw at it. It is anti-magnetic and shock-resistant. Plus, the bezel is raised above it to protect the screen from damage and scratches.

Water resistance

The water resistance is up to 200 meters, which usually implies you can dive while wearing your watch. Still, as the seals are exposed to different environments, the water resistance will deteriorate over time.


This model’s type of movement is quartz which makes the watch accurate. Therefore, its battery can be charged in two ways. Either by using the solar power feature, which creates energy for movement via sun and ambient light, or the battery power function. 

The second option is to use a charging cradle. It also includes a battery power indicator to help you keep track of how much energy is left in the battery.



The timepiece uses sapphire crystal. Sapphire is highly robust and scratch-resistant, making it the ideal material for a high-quality timepiece. While sapphire is relatively pricey, it has advantages because of its resistance to scratches and shatters. In addition to being scratch resistant, a sapphire crystal is more resistant to cracks and breakage than glass or plastic.


This watch, like most G-Shocks, has a digital LCD screen rather than an analog display.

The screen has an outside ring that displays information regarding the button functionalities. There isn’t much to say about the screen itself. It is round and not divided into sections like other G-Shocks.


This model uses carbon tubes for the strap, which are needed to secure the straps to the case. The carbon tubes have the advantage of being more solid and good at keeping the strap from falling off your wrist.

The strap is also quite long. Overall, it is great to wear over a jacket or suit or suit larger wrists.

Other special features

The Casio ABC sensor system, which comprises an altimeter, barometer, and compass, is featured on the watch. It also comes with a thermometer.

Another characteristic that differentiates this watch from others is its GPS function. While the GPS function is fantastic, it does consume a lot of energy, thus depending on how often you use the GPS function, the battery will run out differently.

Pros & cons


  • High in shock resistance
  • A great combination of GPS and solar charging
  • Wireless charging 
  • Simple controls and menu system
  • Cool, tough looks


  • The large size makes it unsuitable for all wrists
  • Expensive


1. Is Rangeman the best G-Shock?

If you’re a tough worker, the Casio G-Shock Rangeman range contains without a doubt the most exclusive and greatest items that perfectly meet your needs. In addition, the timepieces are durable enough to support you in any scenario, no matter how severe the environment or how low the temperature is.

2. What is the difference between the Japanese and American versions?

They function the same way. However, the Japanese ones have considerably prettier packaging, and some think they are somewhat better built.

3. If GPS is disabled, can the watch be fully charged using only light?

Yes, it is possible. When GPS is turned off, it performs similarly to other solar watches. When GPS is activated, it will also automatically switch off GPS when the battery runs low, allowing it to function as one of their other solar watches.

Final Thoughts

All in all, our Casio G-Shock Rangeman GPR-B1000 review has shown that this watch is a G-Shock on steroids in all different ways. Its design is out of the world, and so are its functions.

In terms of build quality, this is a truly tough watch capable of outstanding performance. If you’re searching for a timepiece that can take almost any situation you throw at it while still providing a plethora of various functions, this is the right watch for you.
