G-Shock gains heartrate sensor, takes on Garmin and the apocalypse


We’ve had smart watches and fitness bands with heart rate sensors for a few years now. We’ve seen Casio smart watches with Bluetooth, whether they had analog dials, digital, or were all-out Android Wear. Now, for the first time, heart rate is built in the G-Shock MOVE GBD-H1000.

What if you wanted something that competed with a Garmin Fenix? The new GBD-H1000 has heartrate sensing built-in, as well as V2Omax, which uses heart rate and running speed to calculate the maximum consumable oxygen uptake per kilogram of bodyweight in one minute (ml/kg/min).

This can be used as a benchmark for cardiorespiratory ability when you’retrying to build endurance for running or other sports.

It also can be useful for understanding how fit you are, based on age and amount of oxygen you can consume (that V20max number.)

Power up

The G-SHOCK MOVE GBD-H1000 is solar powered, first of all. When charged about eight hours every day under indoor fluorescent lighting (500 lux), and charged at window side on a sunny day for two hours in a week (10,000 lux), it can be used for daily wear.

Solar-assisted charging

Time mode (includes step count measurement and notification functions) can be powered with solar charging alone.

GPS and the heart rate measurement require more juice, and charge over USB with its dedicated charge cable. After about 2.5 hours of charging, training features can be used continuously for up to 14 hours. Because you charge with USB and Solar, CASIO calls it solar-assisted charging.

OK, that’s how it charges. What can it do?


Optical sensors on case back of watch LED light, detect the blood flow under the skin, and measure heart rate. This is pretty common – we’ve had these for years on FitBits, Apple Watch, Intel Basis, and others. But it’s the first time we’ve had one on a G-SHOCK.

Again, this is pretty common. Casio is using a 3-axis accelerometer to detect body movements, measure step count and distance traveled. They’re also using it to interpolate distance measurements in conditions where GPS measurement is unavailable.


There’s a built-in miniature sensor that takes measurements of compass bearing, altitude, barometric pressure, and temperature. Compass bearing and altitude information improve the accuracy of GPS distance measurements.

Magnetic Sensor, Pressure Sensor and Thermo Sensor

Oh, and GPS.

The G-Shock uses GPS to measure distance traveled, speed, pace, and more. It sets the time from the GPS satellites. If you pair it with a smartphone, it can display your routes traveled.

Display of Route Travelled

The data is stored in the watch, and you can customize the display. Casio calls this Memory in Pixel. The smartphone also sends it vibrations on email and other notifications.

Those notifications are phone calls, email, and message receipt notifications. You can check them while exercising, unless you’re in training mode.

Because it’s a G-Shock, it’s shock resistant and water-resistant to 200 meters. The display is protected by a mineral glass crystal.

20-bar Water Resistance

Design-wise, the urethane band connects to the case of the watch, and the metal bezel and buttons are protected by resin protectors over the top.

The G-Shock MOVE is a runner’s watch. It’s a trainer’s watch. It’s a step, surfer, world traveler’s watch. As long as there’s sun, USB charging, and satellites in the sky, it’s an apocalypse watch, and will keep time without setting until 2099. The GBD-H1000 is expected to be US $399.

Thank you for reading this WristWatchReview post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

WristWatchReview is one of the few remaining truly independent watch news outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent watch sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis. We don't play the games the other sites play and we've paid for it when it comes to ad revenue.

We would love for you to support us on Patreon and every little bit helps. Thank you.
