Conquer demanding terrain and feel amazing with a rugged timepiece as bold and active as it is tough. Designed to work in the harshest environments, the G-SHOCK RANGEMAN GPRH1000 from the MASTER of G line is a truly tough piece of outdoor gear. With a mud-resistant structure to keep out fine dust and dirt, it is designed to withstand the most punishing conditions and the worst weather situations. This rugged timepiece is equipped with solar assisted charging, a heart rate monitor, built-in GPS functionality, and a high- definition, high-contrast memory-in-pixel (MIP) LCD for an easy read. The case is guarded by sizable metal components on the left and right, protecting the GPS antenna and six sensors inside, to deliver what you need for a wide range of activities. The trekking function allows you to check your heart rate while on the move so you can keep track of your physical condition during workouts. Check the tide graph for low and high tides to get the most out of water sports. Enjoy all this functionality, with no sacrifice in comfort. The soft urethane band delivers a comfortable fit that your wrist will love and is textured on the top side so that even wet fingers can tighten it without slipping. The case, bezel, and band are made with bio-based resin, a material expected to help reduce environmental impact. With the engraved silhouette of the RANGEMAN wild cat character on a band piece, every detail of this timepiece exemplifies the spirit of this MASTER of G line of specialty watches.

Review Image by JG De la Rosa
UPDATE. After this being my main watch for over a month, I have found a lot of things about it that I would like to share. First, this is NOT a smart watch, you can't compare this to an Apple Watch, Garmin, Samsung, etc. This watch is a hybrid and it is a "regular" watch at its core with some Fitness tracking capabilities. Which to me, it is perfect! The battery lasts very long, I have enabled heart rate monitor to be always on + I workout every weekday for about an hour and the occasional hiking or pool swimming on weekends and on average the battery lasts me (to have just 2 bars out of 5) about 12 - 15 days. I recharge the watch when it has 2 battery bars as I have read in different forums that is a best practice to keep your watch running virtually forever. The Workouts, steps and HR can be sent automatically to Apple Health and Strava, which even though I tried Strava, I ended up deleting it as I did not see any added benefit compared to Apple Health other than the "social" aspect which I don't care, plus, it is a subscription based app, so no thanks. Sleep tracking cannot be transferred over to Apple Health which it was a bit of disappointment but I can live without it. The Casio Watches app although it is not top notch, it is not comparable to other Apps like those used by Garmin, Samsung etc. It does its job. It keep records of all your vitals and workouts in one place, which is enough for me. I found the Sleep tracking info arguably better than Apple Health (Paired with the Apple Watch) as it provides more insight. Like you get a score for your sleep quality and time and also you get a score for something called Autonomic Nervous System (ANS), which tells you the strain of your workouts, and you get some insight on that, as if you need to push harder, or take it easy that day, which I find kind of helpful. One thing I struggled at first was with the "nighttime", in my case, I was treating it as I did with my Apple Watch, in the sense, that if I went out for vacations (which I did during this one moth time period) I would just change the start and end sleep time in my watch and hope to record it whenever I wanted, or even deactivate it and reactivate it on command whenever I was going to bed. But doing that gave me a negative experience, right after I modified the nighttime setting, my watch stopped recording my sleep score (which for some reason I am obsessed with) and I could not figure it out, until, after some reasoning I discovered I should not mess with the nighttime setting, so what I did was to set up a time that is not that accurate, like go to bed to 9 pm and wake up at 9 am, which that is not true as on weekdays I typically go to bed at 9pm but wake up at 5, and on weekends I go to bed around 10.30 - 11pm and wake up around 8 - 8.30 am, so after I did that, I started getting accurate readings every single night, last weekend I went to bed at 1am and woke up around 9.30 and it give me my sleep recording accurately. One thing I have read on Reddit or other places is the buttons are a bit mushy, but I dont think that is the case, I think the watch has a slight delay when you press the button and when you get some feed back ether on its screen or by sound or vibration. Which I got used to it once I understood this was not my Apple Watch, I understand for some people this might be annoying but for me, I am ok with it. The GPS signal works fine, it is not the fastest out there, but it is ok, when I go hiking it could delay me 10 seconds till a I get good GPS reception which let's be honest, it is nothing, plus Casio has been releasing some GPS updates that have improved that waiting time and accuracy (these updates are different than the firmware update which I have gotten 1 thus far since I bought it). And lastly, I have read you cannot disable the backlight when you press the buttons but yes you do, you just need to silence it and set it on vibration only, which in my case, it is what I wanted. So overall I think this watch is super cool, good looking, tough, has a lot of functions, it works great for my needs (btw. I disabled notification on the watch since I was sick and tired of them in my Apple Watch and was one of the main reasons to get a different watch). It is accurate and the App although it is not super advanced or anything, it gives you all the data you need for your workouts. I 100% recommend this watch if you like outdoors and to workout, as you dont have to worry about battery life or cracking/scratching your smartwatch crystal display. _____________________________________________________________________________ I have just tried it for a couple of hours but so far, I can tell the following: 1. Super comfortable, I am used to big watched, I have several considered "big" like the Mudmaster GGB100, and this feels much smaller and more comfortable, I even find it more comfortable than my apple watch series 7 (45mm) 2. super easy to setup with the app 3. I have had no issues to read the watch, even with the "controversial" negative display, it is easy to read 4. Strap is great quality, it is soft, and comfy 5. Has a lot of functions including workouts 6. Which is one of the selling points for me (besides the other 5 XD) is that the Casio Watches app, can transfer the data to apple health This is particularly important to me, one of the main reasons I felt "stuck" with the apple watch was that I am an apple fitness + subscriber and I did not wat to lose all the "goodies" but I think this is an alternative to stop using it and still getting all my workouts recorded. My intentions are to have it as my daily beater, so I will update this review after a week or two, when I have had more workouts recorded and sent over apple health to see how that works. So far, it is a looker with a lot of functions! plus is solar! ... show more

    • Very impressed!
I have a few G Shock's now and the GPR-H1000-1JR is really quite a wonderful watch. It's not exactly a sports watch, but more of a hybrid built-in a rangeman body. I bought the black/grey, it looks tough, and it's really lovely. The photos don't really do it justice. I've had the GPR-H1000-1JR for a few days already, and I haven't touched the charger yet since taking it out of the box. All bars are 100% - I have done due diligence in order to save power - no need to have my heartbeat measured all day - I only use those measurements at night to track my sleep and when I'm jogging. The Strava integration is nice but limited - it's only one way to the app. All the other functions are great - the barometer works accurately. I'll update the review as I learn more. ... show more

    • Not great
I'm a fan of the g shock but, this is unimpressive. It has a good amount of features that interested me like tides, barometer, temp etc. But theyre just badly executed. The tides for example, show only the current state. No way to see the future of a tide, which makes it largely useless. The compass needed constant recalibration and the display was jumpy. The fitness tracker was quite good and the fitness apps were not bad. But, for over $400. You can get a Garmin base model for half that which performs much much better. The display is amazing but any watch using MIP is just as good. Sadly, I don't feel the software justifies the price. But, it is cool to look at and probably much tougher than a Garmin. ... show more

    • Don’t buy through Amazon
I purchased this watch in February 2025 in November 2025. The main button stopped working rendering the entire watch completely useless. I contacted Casio regarding a warranty, and I was told by Casio that because it was sold by a third-party vendor through Amazon there is no warranty coverage. I will no longer be purchasing watches this way through Amazon nor will I be purchasing any Cassio‘s ever again in the future. Steer clear of third-party vendors as Cassio does not recognize them as authorized dealers and therefore they are not covered under warranty purchasing a $500 watch for it to break less than a year after the purchase is completely unacceptable. ... show more

I read so many reviews saying this watch was huge and was looking forward to a massive watch, but honestly this was smaller than expected and smaller than my Suunto 9 Baro. Has less activities than Suunto but ones more focused on what I do and more details than the Suunto. The Suunto is a great product but I like that this screen is easier to see in the sun and takes my heart rate much more consistently. I thought this was black but it is more of a muted gray which I like a little better. VERY light. Contrary to what people say easy to sleep with to do sleep stats. Not fancy, no frilly colors, but rugged and easy to use. Day 4 and very happy with the purchase (I only run, walk, trek, lift, bike and swim so this hits everything I need). Only complaint is I haven't figured out how to log a run on the treadmill vs outside run...also day 4 with every sensor turned on and only drained 10% battery with 2 GPS activities a day... ... show more

    • Awesome watch
Incredibly happy with this watch. I’ve had it for about a week and wanted to learn all of the features before reviewing. To start off, it’s very well made and looks awesome. For me, it is just the right size. The build quality is solid. Outside of the construction, what makes me really like the watch are all of the various apps. I won’t use all of them as they don’t fit my activities, but will use many. It’s not a smart watch but has many applications that will be useful. What’s interesting is that my battery level has not dropped in five days without a charge. I was expecting a regular need to charge it. The solar assist helps. You can also choose from various watch faces. Overall, I am 100% happy with this watch. It will be my daily wear. ... show more
