Today we have come up with Casio G-Shock GWR-B1000 Gravitymaster Review & Buyer’s Guide and hopefully, you shall find answers to your questions about this beautiful masterpiece.
The Casio G-Shock GWR-B1000 Gravitymaster is a watch included within this G-Shock line dedicated especially to airplane pilots (they are resistant, very reliable, and quite practical watches). This model and all the others stand out for their beautiful analog design with aviation touches and for their advanced technologies.
What are you going to find in this Casio watch? Water resistance up to 200 meters, monocoque carbon case, rust-resistant structure, TRIPLE G RESIST, Bluetooth connectivity, radiofrequency time update, and solar charging… we are the best of the best from Casio right now. And that is paid. It is one of the most expensive watches in the G-Shock line.

As soon as you take it out of the box, which is premium level, you realize that you are dealing with a G-Shock quite different from what Casio has accustomed us to: Carbon Core Guard structure, the back, and the front are joined by a thin blue line and everything has curved lines.
Thanks to this very, very strong structure, Casio has been able to eliminate the button protection found on other G-Shock watches.
The main dial is boxed by the bezel (which has the typical signs to count time from 05 to 55 but without the bezel moving like in other watches), and the central area is raised: they put G-SHOCK, CASIO, and the window of the day at 3; the lower dial can indicate the second world time (hours and minutes) and in the upper dial you can check the day, the different modes of the watch, and the charge of the watch (it is a solar-charged watch). The hands are white and the indices are in 3D.
- G-SHOCK CONNECTED
- Multiband 6
- Tough Solar
- Triple G Resist
- Japan Imported
A few details that may interest you:
- The bezel is made of laminated carbon and has a quite striking diamond pattern.
- The structure is a Carbon Core Guard (carbon monocoque box made of carbon fiber reinforced resin). The watch is stronger and lighter than any other Gravity Master model.
- The new case structure has been modified to block a direct impact on the button axis and the internal circuitry of the module. That’s why there are no button protectors.
- All external metal parts of the watch are made of titanium (lighter): so it is resistant to rust.
- The crystal is scratch-resistant sapphire.
- The crown is really screwed in (it is not an aesthetic issue).
- The watch’s Triple G resistance offers protection against centrifugal force, shock, and vibration.
The buttons are rounded in blue tones with a pattern in the form of small triangles (in the GWR-B1000-1A1ER version of this review, then we also have the GWR-B1000-1AER in dark tones and the GWR-B1000HJ-1ADR with the dial). in white tones and a plane in one of the small spheres).
The crown is quite striking (it has two positions), which can bother your hand a bit if you wear the watch very tight (it protrudes quite a bit) and the front button to turn on the LED light (quite a powerful light… by the way).
The LED light illuminates even in the dark, and the fluorescent is powerfully applied to the indices and hands of the watch. It is not necessary to turn on the light at night, with the brightness of the hands you can see everything perfectly. You can also see the numbers 3, 6, 9, and 12. And it lasts all night without a problem.
The back is also striking: completely rounded and forming a unitary whole with the rest of the watch. Very nice. Very sturdy. Casio tells us the features of the watch:
- WATER-RESISTANT 20BAR
- CARBON MONOCOQUE
- Module number: 5588 and model GWR-B1000
- TOUGH MOVEMENT
- IC data, FCC ID and symbol of Bluetooth, and others
The truth is that if I could put my watch upside down… I would: that back part has a spectacular design.
Casio G-Shock GWR-B1000 Gravitymaster: Comfort and Strap
The truth: It’s not the most comfortable G-Shock in the world, and the main culprit is the resin and carbon fiber strap. It is really hard and firmer than usual. It gives a very elegant look to the watch, but it fits poorly on the wrist during the first months of use of the watch until it wears off.
- The good thing about this form is resin + carbon? That you are going to have a leash for many, many years. I don’t think it will break.
In addition, the loop does not hold the end of the strap very well, which protrudes quite a bit from the wrist and does not remain curved as in other watches. An aesthetic flaw that can martyr you if you are very picky.
As for its size: not bad (50.1mm x 46.4mm x 16.9mm). The only thing that can bother you is the crown button when touching the hand. Its weight is only 72 grams, so it is quite light.
Casio G-Shock GWR-B1000 Gravitymaster: How It Works
The good thing about the watch having Bluetooth connectivity with the G-Shock Connected app is that it has a very good operating guide where that explains the use of all the buttons and associated functions. It is a very complete watch (but it does not have sensors like other G-Shock watches).
This watch has a flyback or flight recording function: by simply pressing the button you can reset the current timing, and by pressing it again, the stopwatch starts a new time measurement. You will be able to record several intervals and then see the result in the app:
It also has a daily alarm, universal time function, and Smart Access system thanks to the electronic crown (you can quickly access all the important functions of the watch. You can switch between the different modes to manage the stopwatch, the timer, the alarm or universal time).
It also has an automatic adjustment of the hands, to prevent the watch from losing or advancing.
It also syncs the time via Multiband 6, but it’s probably easier to keep the time on the dot thanks to Bluetooth connectivity with the app.
The solar energy system works really well and if you put it in the sun a little every day, you will have a battery and accumulator for a while. This Gravitymaster will run for 5 months on a full charge with normal use. In energy-saving mode, it will last for 18 months.
Casio G-Shock GWR-B1000 Gravitymaster: App and Bluetooth Connectivity
Well, the truth is that the beginning was not good, since the watch did not connect via Bluetooth to the Casio app on an iPhone. You just have to search the internet a bit to find out how to solve these connectivity problems.
It could be several things, but in this case, I had to completely delete the pairing information from the watch:
- You loosen the crown and then pull it out to the second click.
- You hold down the button (B) for at least 10 seconds (look in the manual for this button on your watch): This deletes the pairing information.
- Push the crown back in and lock it.
Then everything started working fine and the watch linked to the Casio app on an iPhone (iOS). There is also an Android app.
The good thing about accessing the app is that you will be able to configure all the parameters of the clock in a very visual way. It is not essential to use the app (everything can be done with just the buttons and crown), but it is more comfortable.
As soon as you enter the app you can check the operating guide, see the solar charge it has (top left), check the flight log, or change the alarms. The time is automatically synchronized every so often.
Then you can access the toothed wheel (top right) and modify all the parameters of the clock such as sounds, light settings, start positions of the hands, summertime, etc… Remember to send the changes made to the clock by pressing the big button bottom red.
It is not a smartwatch to use. It has smart features, but only to make your life easier, not to receive notifications from your smartphone.
Casio G-Shock GWR-B1000 vs GR-B200RAF Gravitymaster
The truth is that they do not play in the same league and you may choose one or the other for several different reasons:
- Price: the G-Shock GWR-B1000 is much more expensive (you can get it for between 600 and 700 euros). The GR-B200RAF costs 369 euros on Casio’s page and the “normal” edition, the GR-B200-1AER, 299 euros.
- Construction: G-Shock GWR-B1000 (premium materials, very light with solar charge and sapphire glass); GR-B200RAF (mineral glass, resin strap, works with a battery -2 years- and does not have a solar charge). The GR-B200RAF also has a carbon-reinforced case and bezel, but the build is more typical and the back is screwed on.
- Sensors: The GR-B200RAF and GR-B200-1AER are loaded with sensors that the premium model doesn’t have: a barometer, compass, altimeter, step counter, thermometer, and height sum.
- Design: It changes a lot. Neither better nor worse. You have to like one or the other. The GR-B200RAF sits larger on the wrist.
Both models have Bluetooth connectivity and a “pilot’s watch” design.
Conclusion: Is the Casio G-Shock GWR-B1000 Gravitymaster watch worth buying?
It is an expensive watch, quite expensive, but there is no doubt that its manufacturing quality is premium since it has a sapphire crystal, carbon fiber everywhere, and a very special block-built case. His resistance is more than proven.
It is a watch with Bluetooth connectivity, solar charging, and Multiband 6, but it does not have the sensors of its “brother” GR-B200.
The design is the most striking of this model. It is very light and fits very well on the wrist, although the strap is somewhat stiff (the watch is not very comfortable during the first months of use. Until the strap loosens a bit).
- Premium manufacturing with sapphire crystal, and carbon fiber on the strap, case, and bezel
- anti-corrosive casing

- Flyback function for pilots
- Indexes and hands with a very good fluorescent coating
- Somewhat stiff strap the first few months
- The crown can bother a bit
