Casio G-Shock Gravitymaster GPW-2000 GPS Bluetooth Watch Review

Casio G-Shock Gravitymaster GPW-2000 GPS Bluetooth Watch Review Wrist Time Reviews

It was easy for me to recommend Casio’s latest G-Shock Gravitymaster watch to the friendly US Air Force captain who contacted aBlogtoWatch seeking advice on watches to get for his particular squadron – especially because they were keen on finding a traditional watch with GPS. The Casio G-Shock Gravitymaster GPW-2000 (aka GPW-2000, and seen here as the reference GPW-2000-3A or GPW-2000-1A) is the high-tech Japanese watchmaker’s latest timepiece to incorporate their in-house made GPS system, along with a lot of other tech which in my opinion makes a timepiece such as this truly state-of-the-art. That is a rare designation on aBlogtoWatch because the majority of timepieces we write about might be new, but use older (mechanical watches) versus very modern technology. Casio is among the rare brands which in my opinion are actually making timepieces that feel like an authentic expression of our contemporary times – with impressive functions and pricing that isn’t purely luxury-minded.

With this in mind, I review Casio G-Shock watches for style, quality, as well as functionality – as the latter is a huge part of the Casio product value proposition. Over the last few years, Casio has been stepping up the quality, sophistication, and price of its higher-end G-Shock watches – and it has truly been impressive to see what they’ve done. Casio is fighting an interesting battle because on one end they must meet the aesthetic and material expectations of increasingly sophisticated watch lovers, and at the same time satisfy the engineers that make up the company by producing actually relevant “useful” watches that are priced as competitively as possible. So how does the 2017 GPW-2000 measure up and fit into their strategy?

For some history about the Gravitymaster collection, including more technical specs about the GPW-2000 please see our debut hands-on article of the Casio G-Shock Gravitymaster GPW-2000 watch here. It is a follow-up to the GPW-1000, which also featured GPS but was appreciably larger in size and in my opinion not as visually attractive. Baselworld 2017 saw the welcome release of this new Gravitymaster and I think Casio is finally able to offer a very compelling GPS-based traditional (versus non-smart) watch. The other new Casio watch that also includes GPS is in fact a smartwatch, which is the Casio ProTrek WSD-F20. Both of these timepieces are good products, but so different that I would say they are for totally distinct types of customers.

The Casio GPW-2000 doesn’t just feature GPS but also Bluetooth. Doesn’t that make it a smartwatch? Perhaps, but not in the sense that it has a touchscreen and needs to be charged on a daily basis. Timepieces such as this represent Casio’s latest effort in their ongoing mission to have useful watches that you never need to fiddle with. The watch recharges the internal battery using sunlight (or any ambient light), and the GPS and other systems are mainly included in order to ensure that the time and calendar setting are always accurate – no matter where you are in the world. “Gravitymaster” is the term Casio uses for their nicer pilot-themed watches, so there are also some features in this timepiece which are intended for aviators of all kinds. That begins with the relatively (for a Casio) clean and very legible dial which I have come to really appreciate.

Before talking about the design of the watch I want to talk tech a bit more. I will not examine each feature of the watch in a lot of detail for two main reasons. One, this article could go on for many pages if I was to detail the features available in this watch, and second, I want to focus on what the average wearer will likely use in their daily life.

I discussed this at length in the launch hands-on article of the GPW-2000 – so I won’t explain it again in as much detail – but let’s talk about accuracy. Casio is obsessed with the idea that the perfect watch requires almost no intervention from the user to be reliable. For that reason they have engineered out the need to change the battery or set the time – but this is a process where previous innovations are continuously built upon. The GPW-2000 offers a new “triple redundancy” feature designed to make sure the time is always accurate – and to my knowledge no other watch company offers anything like this.

Casio G-Shock Gravitymaster GPW-2000 GPS Bluetooth Watch Review Wrist Time Reviews

In order to get the accurate time, the watch must reference outside information and it can do this in three ways. The order it chooses to get this information (it checks daily automatically or can be manually done) is based on what uses the least amount of power – thus promoting operational efficiency. The watch first uses Bluetooth to ping a paired mobile phone to check internet time. There is an application associated with the watch (G-SHOCK CONNECTED) that you download in order to facilitate this connection. Oh, and a cool thing about the app is that it updates itself when time zones change around the world (as well as DST), so the watch itself always represents the current state of global time zones.

Thus, the more efficient way for the watch to get the accurate time is to get the internet time via a smartphone’s internet connection and Bluetooth. If that fails, then the watch uses its radio signal receiver and takes messages from any available atomic clock signals. This is efficient but it does require being in a place where the signals can be received. That means not only being in the right parts of the world, but also not being inside of a building where radio signals would often be shielded. If that all fails, then the watch receives signals from GPS satellites, which should do the trick. This is a robust and interesting system with the goal of simply making sure that no matter where you are in the world your time is accurate.

How well does it work? I’ve never really known how well the automatic updates work but the watch always does seem to be on time. When I manually update the time it works very well and is surprisingly quick. I did notice however – and this is common with pretty much all non-smart Bluetooth watches, that sometimes it can be challenging to connect and stay connected to a paired device. This isn’t really Casio’s fault so much as it is an issue with Bluetooth and a lot of other software that they can’t control. To make a long story short, if you are traveling, you might need to spend a quick second manually updating the time (a single button press is usually all that is needed) and you get the updated time right away in a rather satisfying manner.

    I like it. but unfortunately indeed a bit expensive for a g-shock.

    • Kuroji


  • IanE

    Looks very legible, but I wish the main hands were all a bit longer. 57 mm does seem enormous – even my rather large Protrek is ‘only’ 50 mm and is only wearable because of the very short downward-pointing lugs – I doubt if I could wear this G-Shock: maybe the next gen!

  • SuperStrapper

    Interested in trying out thebapp to control/set the watch. G shock function controls are not difficult, But they are specific and have a real learning curve to them. Changing settings from a app screen is likely quite easy and intuitive.

  • Bozzor

    Way too big for me, but tough, practical and useful. There is a real market for this and good to see ABTW understands that as nice as a Vacheron Constaintin Overseas Chronograph is, it may not be the watch to take with you for hunting in the wilds of Alaska, skate boarding in Seattle or taking a small plane across Europe.

  • Dénes Albert

    If I were a survivalist, I would immediately order two of these, just to be on the safe side. In all other scenarios, I sincerely doubt that the undeniable wealth of features offsets the impractical size and steep price. OK, maybe if you’re lost in the Mongolian mountains you would want to know your location, but as nice that would be, the more sensible thing is to let _others_ know where you are. I’m thinking Breitling Emergency. Do they still make them?

    • SuperStrapper

      It’s a bit of an apple’s and oranges comparison, but interesting. The emergency (ii, so you can have access to the 406mz freq, the original emergency only uses the 121.5mz channel with is still monitored but not in regular use) like you mention let’s others know where you are, but they have to be looking for you, and that’s all the help it provides. I personally would prefer to be able to help myself (ideallynwould have both options I suppose) and in the case of the emergency, even the 406mz signal will give a 65-70km search area to work with initially. These people are great at what they do, but in a hard mountain range it’s no easy task. If you’re there in the first place it should easily be assumed you know what you’re doing, so again there might just be better value in having tools you can use to help yourself. There’s also the $15000+ price delta between the emergency and this watch.

  • Raymond Wilkie

    As subtle as a brick,………..wait, it is a brick.

    • SuperStrapper

      It’s not trying to be subtle. Would you feel bad if I told everyone you perform ballet like a box of angry possums falling down the stairs?

      • Raymond Wilkie

        At least i try ! it’s hard being different !

        • SuperStrapper

          Ah. So it’s ok for you an nobody else. Got it. I understand a little bit more about Ray with each post.

    • Berndt Norten

      It’s mighty mighty
      Ray’s lettin it all hang out

      • Raymond Wilkie

        There’s a time and a place for all that !

        • Berndt Norten

          I agree. Generally when I’m listening to the song, ‘Brick House’

          • Raymond Wilkie

            I find a bit of Barry White does the trick.

    • Sheez Gagoo

      I love Casios. I had a G-Shock 5600 during my army time and I don`t think there`s any better watch than a Casio. As a kid I had Casios to, nobody starts as a watch afficionado with a Blancpain. I know, as a Swiss it should be forbidden to love them, but they are simply to good.

    • Gokart Mozart

      But what looks better, its a tough choice, even though for a gshock it has a pretty restrained dial.

  • Luanero

    It looks like the long & lat display would be precise enough to tell what continent you’re on (or above I suppose), but that’s about it. Pure gimmick really. The waypoint feature is kind of cool though, a ‘handy’ backup if all your other systems fail, but I doubt it could tag accurately enough for my purposes. Casio are almost there with the whole ‘connected’ thing with their latest in the Oceanus line (eg OCW-G2000C-1A) being nicely sized with sapphire (unlike Edifice’s mineral) and not too much crap on the dial (with each evolution there seems to be less). Pity it costs so much though (~US$2-3k)… Great company – my first watch was a bright yellow G-Shock – I thought it cool then and do so now but for totally different reasons.

    • Palettj

      Its $800 bucks retail, probably a bit discounted on Amazon.

      • Luanero

        I guess the moral of the story is that sometimes you just have to read things more carefully.

  • Phil leavell

    Darn good thing it’s not Swiss made .
    Hell the price would be $80,000 plus 10 G’s-hock for wrist Swatch tax

  • WatchNeophyte

    Love the G-Shocks with the Atomic Times, I have a GWM500A-1 that I purchased recently and I love it. This is terrific, just way too big for my wrist. Man, just like the ole 90’s jam “Wish I was a bit taller”, that is how I feel right now, because I would get this right away if I could. Because of its size, I just can’t buy it, but would accept it as a gift to resell or regift. Very nice indeed.

  • John Stevens

    These G shocks are so ugly I almost want one. If I was going to buy a digital watch a G shock it would be, they are the Swiss army knife of watches and I would then probably join the foreign legion to test it’s toughness.

    • Juan-Antonio Garcia

      Let us know the results 🙂

  • Yan Fin

    As much as I like gadgets, the Bluetooth part makes not much sense. It implies that your phone should work everywhere while you are traveling. Now, if you are businessman, your phone probably will work, but GShock will not fit under the shirt. If you’re great outdoorsman, you most likely are in places without cell reception, and also not in GPS zone. Of course, if you’re military, it’s another story.

    • Elijs Dima

      What if you’re neither Businessman, Outdoorsman or Militaryman, but are just, y’know, a normal person traveling for normal people reasons (vacation, family visit, professional conference, a weekend trip)?

      P.S. the bluetooth part makes a lot of sense also if you’re not travelling – the watch’s internal clock will go out of sync slowly, so pinging the smartphone through Bluetooth is the most energy-efficient way to re-synchronize the internal quartz clock.

      • Yan Fin

        Then, of course, atomic time sync wouldn’t be accurate enough for you. And with solar battery you really should be concerned about power reserve. What I am trying to say : better is the enemy of good.

    • Kuroji

      Not in GPS zone?

  • Thanks for the review Ariel. I have been impressed with the advances Casio has made with this category of movements over the last few years. I have a GWG-1000 (non-GPS) and am very happy with the reception improvements they have made to acquire the atomic clock signal over previous iterations. I also have a MR-G 1000 (with GPS) and find its ability to access the satellite system to be very good, and better than other manufacturers systems with which I’ve had some experience. The GPW-2000 just might be the replacement for the GWG-1000.

  • Word Merchant

    Something very appealing about this, and if you need something as solid as this you have few choices anyway. Having grown up with Casios I have a soft spot for the brand, even though I wish they’d resurrect a few models from their glory years instead of endless G-Shocks. I guess $800 is at the absolute very tops I’d pay for a Casio – the MR-G and beyond range is priced way beyond where I see Casio.

    If you want this sort of look but don’t want to pay quite this sort of money, the G-Steel range is worth checking out. I’ve seen this one in the flesh – – and it’s quite cool in a Judge Dredd sort of way. I can imagine if you bought one for a nephew or grandson you’d be seen as pretty cool (for around 30 mins or so).

    It’s not for me, but I’m glad it exists.

  • awildermode

    All those photos and no lume shot?

  • Larry Holmack

    Well’s…I’s a almost bought me one of dese dere G-Shockey’s before dat dere eclipsey of da sun last week! Sincening some preacher’s in da hill dun said dat the 4 hourseriders of da apacoliptic times was gonna appear outta da sky and start an arm-e-geddon….well…I’s dun figured I’s a better get me one of dem fancy watches!
    Since ain’t nothin’ dun happened….well…I dun had da wifey bring all of the ‘shine outta da bomby shelter…and we ‘s dun throwed a big party! Too bad I’s ain’t got dat dere Ariel’s telephony number…he coulda dropped by, had some shine and showed us some of his fancified watcheys!!
    Next time I’s’ll let y’all folks knows when we’s a having a piggie roast and y’alls can come ta da hill’s and have some BarBQ and ‘shine!!!

    • Guillermo Grodiño

      Now dat dere sounds like a good timey.

  • Juan-Antonio Garcia

    Good review, it is getting me closer to pulling the trigger on this one. Lots of quality for the buck. Great for traveling in not so friendly places, these Casio are great tools, the dual time, alarms, timers, and if anything else fails, you can trow it to face of the would be kidnappers. The only thing holding me back is the size on my wrist, will have to try on to decide. Also, I would feel guilty as i love my faithful GW-A1000. Time will tell.

  • Kuroji

    Why does Casio not put Tough Solar on the case anywhere? They seem to have rebranded a bit and now Tough MVT means Multiband 6 + Tough Solar + Hybrid design + Automatic pointer calibration.

  • Date looks hideous, and why there’s a recession way longer than the date window? Day even worse particularly with almost showing prev/next days. And I’ve always thought G-Shocks should be digital, no argument there.

    BUT as almost every high end G-Shock: impressively beautiful!

    There’s simply no better watches.

  • Han Cnx

    It’s okay.. biggest challenge may be the looks. Seiko does a GPS watch (Astron) that -while still a busy affair- looks a lot less like a plastic toy.

    • Bozzor

      This is a great watch, but you would be tempting fate if you were to take it into some of the situations the Casio is designed for. The Seiko is an office and business class travel watch: the Casio is for the wild outdoors.

    • riposte

      You should check Casio Oceanus or Citizen Attesa, alternative to Seiko Astron

    Hi Ariel Adams. Thank you it’s a good articles to read about gpw2000.

    I’m glad if you andcall tge members here could join us in facebook group name ‘gravity master gpw worldwide collectors’

    Thank you!

  • Ulysses31

    If I spent $800 on something I wouldn’t want to knock it around enough to test how durable it was, so the “toughness” of this watch is a bit of a moot point for me, as it is with any expensive watch. The functionality is great, the progress in technology admirable, and yet I just can’t get over that Eighties aesthetic. I keep expecting it to transform into a plastic toy robot for a child to play with. Make it look more like a Suunto or something.

If you’re great outdoorsman, you most likely are in places without cell reception, and also not in GPS zone. Of course, if you’re military, it’s another story. Anyways, I think if you want something like GShock, combination of solar battery and radio atomic time sync should be enough.

    ‘and also not in the GPS Zone’

    Hi Yan, I thought we are always in the GPS zone. Unless you are in a buildings/under things/etc……or the Koreans have blown them up.
