The Casio G-Shock is a true smartwatch with heart-rate sensor and notifications

The latest addition to Casio’s growing collection of Bluetooth-connected watches comes with a heart rate sensor and GPS, along with a versatile charging and power system, and is the first to show notifications from your phone on its screen. This makes the GBD-H1000-1A7 the first G-Shock to truly be considered a smartwatch, although Casio also makes the WearOS-powered Pro Trek WSD-F30, and has been dabbling with adding simple activity tracking and other connected features in everything from the Mudmaster to its non-touchscreen Pro Trek models.

Unlike most other G-Shock models, the GBD-H1000 has a MIP LCD screen on the front, rather than the usual analog, digital, or hybrid dials, making it appear very similar to the GPR-B1000 Rangeman. There are further similarities between the two as well. The H1000 is primarily solar-powered, but because the heart rate sensor and notification alerts will need additional energy to function, attaching a USB charger to the back of the case can be used to top the battery up. The Rangeman has wireless charging to power the GPS when the watch’s solar energy is depleted.

Another new feature for G-Shock connected watches is the addition of notifications. The LCD screen will show an alert for new events on your phone, including emails, messages, calls, and calendar notifications. Examples on G-Shock’s global site show the screen will provide detailed information, too, rather than a simple notification message. The watch will have to be connected to your phone for this to operate, which will almost certainly require the watch to be charged up using the USB charger on a regular basis.

While the B1000 Rangeman is for hikers, the H1000 is clearly aimed at runners, and fits into the G-Squad family of fitness watches. The sportier colors matched to the sleeker design back this up. The case back has curved sections to provide greater comfort and ensure the heart rate sensor stays in contact with your arm, while the urethane band shouldn’t get uncomfortably sweaty. The buttons on the case are large and grippy, so they’re easy to press on the move. When connected to your phone, the watch will auto adjust the time, and in the app you can also set alarms, activate timers, and even set world time zones.

GPS and the heart rate sensor are joined by the sensors we expect on most high-end G-Shocks — a compass, air pressure and altitude, a thermometer, and an accelerometer. The watch uses Bluetooth to connect to an app on your phone, where all the data is collated. Using all the sensors, the watch and app can measure speed, distance, and pace, and can also assess fitness level and recovery time after exercise. The app will have a training log to collect data for up to 100 runs, which will also include aerobic and anaerobic training effects, and syncs with other apps like Strava and Google Fit.

The Casio G-Shock GBD-H1000-1A7 will be available in April through G-Shock’s online stores and retail outlets. Global pricing hasn’t been confirmed yet, but the price in Japan is approximately 50,000 yen, which converts to $450 or 350 British pounds.

The G-Shock MRG-B5000B.

Do you want the very best Casio offers in manufacturing, design, and technology from your new G-Shock, all wrapped up in that highly recognizable square case? In other words, the ultimate version of a truly classic G-Shock watch? If so, the new MRG-B5000B is exactly the model you will want, provided cost is no object. We’ve been wearing it.
What makes MR-G so special?
Although Casio is best known for tough watches that won’t break the bank, Casio also has decades of watchmaking experience, and it showcases its talents most effectively in its highly exclusive MR-G family of watches. These models, its most luxurious, are assembled by hand on Casio’s Premium Production Line located in the Yamagata factory in Japan, where only the company’s most experienced, specially certified technicians work on the top MT-G and MR-G models.

The square G-Shock is one of the most popular models, having been around since the G-Shock brand first started in the early 1980s, and bringing it to the luxury MR-G range is going to see a lot of people reaching for their wallets. What makes it so special? It’s the first time the classic, beloved square G-Shock has been given the MR-G treatment, with most other MR-G models over the past few years featuring an analog dial. There's a huge section of an already large fan base waiting for this.

Striking new Burning Red hybrid G-Shock fitness watches will make you stand out
Casio G Shock Burning Red models.

One of our favorite things about Casio’s G-Shock range of watches is the breadth of choice there is when it comes to colors and styles. We reviewed the simple black version of the GBD-200 Bluetooth fitness watch, but if that’s not bright enough for you then take a look at the new Burning Red series, which paints the GDB-200 and GBA-900 hybrid connected watches in a striking red color.

This titanium, connected G-Shock is a $1,650 sci-fi-inspired design masterpiece
The G Shock GMWB5000TVA on the wrist.

My favorite non-smart watches all tell a story, or at least make me formulate one in my mind. The new Casio G-Shock GMW-B5000TVA’s fits into this perfectly due to its unique design that’s part Mobile Suit Gundam pilot cosplay and part sci-fi inspired timepiece that’d be just at home on the wrist of a character from Aliens as it is on mine.
What makes the design special?
Saying something has a sci-fi-inspired design often means it will have an overly futuristic look, a cheesy name, flashing lights, or references to a material having been used in space. In short, they’re usually pretty embarrassing. Not so with the GMW-B5000TVA. Although Casio makes some references to science fiction — the advertising puts the watch alongside a robot, for example — it’s not something pushed on the watch itself.

It’s a decision that saves the watch from becoming a cliché. The laser-engraved text on the case and bracelet, the color scheme, and the materials are all related to the watch and watchmaking, not some fictional spacecraft dreamed up by a marketing department. The clasp is one of my favorite parts of the watch, and a great example of what I mean. It has the model number of the Casio Bluetooth-equipped module used in the watch etched alongside an explanation of the Multi-Band 6 feature, and a few logos, including one for Bluetooth certification.
