Casio makes a full-on smartwatch with the ProTrek WSD-F20 (the most recent generation version), which is powered by Android Put on.

This Rangeman, however, has a brand-new exclusive operating system that replaces a really familiar system I’ve come to be familiar with for practically two decades now.

Casio fitted the GPRB1000 models with a brand-new display, input system, as well as operating system. It takes a little bit of getting made use of to, yet it is instead sensible and also instinctive.

The most important thing for you to understand is that the crown at 3 o’clock is currently a scroll wheel (as well as pusher) and also is used to browse a great deal of the menu products. It is just one of five input devices around the situation, as the all-metal switches are made in guaranteeing premium quality.


This Rangeman is now component of Casio’s higher-end “Master of G” collection, which among other things, suggests that these watches are really created by Casio in Japan. Master of G watches often tend to be of a better on the whole, as well as come with a more exceptional cost contrasted to what many individuals anticipate in a G-Shock.

With that said claimed, even at a retail price of $800 there is a lot of watch as well as technology packed into this gadget. The Rangeman GPRB1000-1 is conveniently amongst one of the most advanced products Casio has actually ever produced– and we understand it will just improve

Solar power and GPS

You’ll observe that there’s a considerable bezel running around the display screen on the G-Shock Rangeman, however as you might have already presumed there’s an excellent reason that.

Yep, that’s the solar panel, permitting the watch to harness the power of the sun as well as top up its battery.

Specifically, the solar-assisted billing tops up the battery for the GPS. The on-board GPS can be used to outline courses and also track your progression live on-screen.

GPS is typically rather power starving, which means battery life can take a real hit if you’re utilizing it constantly.

A complete basic fee of the G-Shock Rangeman can offer you as much as 33 hrs of continuous GPS usage, however the photovoltaic panel can up that to 2 days, allowing you to track your place for two full days in the wild without the requirement to find an alternative power source.

Four hrs of sunlight will certainly produce around one hour of GPS usage, so it’s not the fastest, yet it can well make all the distinction if you are somewhere remote.

Display and Interface.

Unlike the majority of smartwatches, the Casio G-Shock Rangeman has an instead standard black and white screen.

It makes good sense, as it’s less complicated to see in intense light and is less power starving, providing you far better battery life.

Thanks to the sizable bezel of the photovoltaic panel though, the screen is additionally rather tiny with menu message being rather little. If your vision isn’t great you might well have a problem reviewing what gets on screen.

It’s also not the most instinctive watch to use, with various menus and also sub-menus, and acronyms of attributes which do not make it clear to a lot more novice users what’s taking place.
