[Live Photos] G-Shock Rangeman GPR-B1000 Hands On

Since it’s initial introduction back in 2013, the G-SHOCK Rangeman series quickly made the rounds in the watch world – soon becoming one of the most valued and desired all-digital G-SHOCK watches. They were released as part of the Master of G lineup – one of the many offerings from Casio that receive meticulous manufacturing oversight in Japan – and boasted not only an intensely durable construction but were built for rugged travelers all over the world. Now, G-SHOCK has upped that ante once again in terms of both connectivity and capability with the release of their GPRB1000 Rangeman watch.

What do we mean exactly? Well, through intense research and design, G-SHOCK was able to build the first-ever Rangeman complete with solar-powered GPS navigation. That groundbreaking feature, combined with their steady lineup of burly backcountry settings already embedded in the watch’s durable build, made us quite curious as to the functionality here and (better yet) reliability this tank-like timepiece could offer those who wish to get as far off the grid as possible. Luckily, we were fortunate enough to take it on a test run ourselves to find out.

One of the first impressions you find with the GPRB1000 Rangeman is its size – clocking in at 60mm. This thing is beefy, to say the least – which in all honesty – is something we’ve come to know and love from G-Shock thanks to their myriad of additional features. Remember, it’s a lifestyle, not just timekeeping. Surprisingly enough, the 142-gram Rangeman remained comfortable and relatively lightweight on the wrist – especially when wearing it loosely. Then again, this isn’t an office watch. Instead, it became clear to us that the newest addition to the Master of G lineup was designed with experienced outdoor adventuring in mind.

From here, we also noticed a certain similarity to their Mudmaster watches. Namely, its meaty appearance and sleek dial surrounded and protected by a nearly indestructible bezel. In fact, the entire watch appears to function as an indestructible timepiece. It’s also the first G-SHOCK to host a ceramic 2mm thick case back as opposed to steel. Reason being, other than weight reduction of course, is that the ceramic construction allows for signals that would otherwise be blocked by metal to pass through with ease. Which brings us to the “meat and potatoes” of the watch so to speak.

Much like their previous iterations, while the watch itself is digital, it isn’t a touchscreen device – which, we found out, was a benefit to its overall construction. Here, it’s all manned by a series of four durable push buttons around the watch’s perimeter that are easily accessible and workable even with gloves on thanks to gaskets located in the buttons, shafts, and shock absorbent silicon working to protect the lower part of the crown. It’s the navigation functionality, however, is where the Rangeman truly shines.

As previously mentioned, what sets this Rangeman apart from the rest is its solar-assisted GPS function – a first for the brand – that we found incredibly useful and handy during our field testing expedition. Also, thanks to the watch’s Bluetooth® low energy technology syncing the piece up with our smartphone to help track and trace our route was both easy and useful.

Basically, G-SHOCK took their already established solar-powered charging technology and implemented it into the functionally of the GPRB1000. Meaning, its GPS tracking process is mainly powered by the sun – assisting you in traveling from point A to point B with on-screen directional guidance via the watch itself. In doing so, routes, landmarks, and waypoints are tracked and marked in the corresponding application and can even be viewed as a 3D map in the G-SHOCK Connected app.
