A 3rd-generation G-Shock Rangeman that straddles two worlds: it can stand alone as a watch with A.B.C. functions and solar charging, and it can operate as a smart sport watch with electric charging.

Among its positives is that aesthetically it looks better than any smart watch out there. It comes in three color options, with a carbon-fiber case base (IF DESIGN AWARD 2025 winner). It’s rugged and lightweight at 92 grams, with a chunky 60 × 53 mm case and... 20 mm thickness!! So think about it: it sticks out from your wrist and bangs into doors! If you’re a tradesman too and wear it, you’ll get it caught on something somewhere. Even so, it sits well on the wrist thanks to the “wings” it has underneath.
The bioresin (made from trash?) silicone strap is soft as butter! With lots of adjustment holes, there’s no way it won’t fit you.
The rechargeable battery lasts 14 hours with GPS on, depending on incoming notifications, of course! Two weeks with the heart rate monitor on, and 23 months with power save.
I got mine charged, but not all the way to full, on high, where it displays the charge level, and I’ve done around five activities totaling about 180 minutes with GPS running, as well as having the heart rate monitor on every night while I sleep. Right now it’s on day sixteen and is showing low battery, which means it needs charging.
As a sport watch, it has some basic activities in the menu, a map in the app with basic exercise and health information, sleep quality, distance traveled, steps, calorie consumption, goal achievement, VO2 max, wellness tips, etc. For the running measurements I have as an activity, I’m including images from the Casio, Polar, and Garmin apps, where the recorded data are very close.
Negatives: Polar’s app is outdated. To connect fully to your phone and have your data recorded from Life Log based on your steps, you also have to keep your phone’s GPS on, which annoys me. It doesn’t connect with Google Fit/Health, only Strava, and many times during exercise, when comparing it with the Garmin, I see that it overestimates the heart rate. Also, slow charging, about three hours!
There are reports from abroad that the Allen screws on the strap loosen, with the risk of losing the watch! (There is a fix: apply blue Loctite threadlocker or Bison’s equivalent.) Then there’s the price, at €500–550, when its direct competitor, the Garmin Instinct 3, costs €350 and offers navigation, and the Garmin Epix costs €400 and also has maps! Well, you have to really like G-Shock to buy it.
The target group is professional first responders, as they’re called—firefighters, healthcare workers, coast guards, etc.—people who are tired of “smarties” but still want to have that option, as well as people with presbyopia, since the MIP display is exemplary even in low light. In conclusion, a watch that will survive the end of the world! It’ll withstand the 200 meters’ depth you’ll go to on the seabed to escape the pyroclastic flow from the eruption!! It’ll roll around in the mud, resist, and serve you without bugs, software updates, or a model change every two years (see Garmin). Manly stuff, you know.

1/10/26 After a month, no problems! Regarding what I mentioned about overestimating heart rate during activity, just wear it a little tighter on your wrist to get accurate readings (so your finger can’t fit between the strap and your wrist).
Battery life is the same: 15 days with the heart rate monitor on while sleeping and 3 hours and 46 minutes with GPS on

Beautiful watch, perfect for everyday use.
Before you buy it, try it on your wrist.
