Delivers shock resistance and 200-meter water resistance even packed with a built-in optical sensor that measures heart rate at the wrist. Five-sensor functions work with the GPS functionality to monitor workouts in real time, connecting with the dedicated app to support training assessments, analyses, and planning.
In addition to an optical sensor that measures heart rate at the wrist—a first for the G-SHOCK line-up—the other sensors on the watch measure acceleration (step counter), magnetic direction (compass), pressure (altimeter/barometer), and temperature (thermometer).
Optical sensors on the back of the watch flash LED light, detect the blood flow under the skin, and measure heart rate.
Acquires data of current location from GPS satellite, measures distance travelled, speed, pace, and other data. In addition to GPS, the watch acquires data from GLONASS and MICHIBIKI (QZSS) satellite systems.
Delivers shock resistant and 200-meter water resistance even with a built-in optical sensor that measures heart rate at the wrist.
Large measurement buttons and two-colored buttons with slip-resistant design enhance operability. The curved surface of the fine resin back cover reduces interference with the back of the hand.
The soft urethane band improves fit. More band holes in the band improve ventilation, and with the band holes closer to each other, fine fitting adjustments are easier.
Displays various detailed measurement data in high contrast for easy viewing. Data displayed when training can be customised for ease of use.
Time mode (includes step count measurement and notification functions) can be powered with solar charging alone.* The watch also offers USB charging which can charge even more quickly. After about 2.5 hours of charging, training features can be used continuously for up to 14 hours.
*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).
Large measurement buttons and two-colored buttons with slip-resistant design enhance operability. The curved surface of the fine resin back cover reduces interference with the back of the hand.
Displays the current heart rate, as well as a heart rate zone that shows exercise intensity at five stages, and is useful for pace management during activities and endurance training.
Heart Rate Zone AlertNotifies with sound or vibration when heart rate deviates from the target zone, making it possible to train with an exercise intensity that is suited to the purpose.
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 the user is trying to build endurance for running or other sports.
Training Analysis AlgorithmUses an algorithm from Firstbeat Technologies, which has a reputation for advanced fitness data analytics. Helps to maximize training effect with highly accurate data analysis.
Smartphone connectivity enables functions from log recording to plan creation, making training management simpler and more convenient.
Easily prepare training plans for goals such as full marathon entry and fitness improvement. Set target heart rate zone, training time, and running distance from the menu display. You can send heart rate zone to the watch for use as an indicator for training.
Data analysed by the watch is clearly displayed and managed in the app. Detect changes in fitness level and training status and use them for training results and future strategy.
Displays list of measurement data for each activity. In addition to running distance, time, pace, and calories burned, also displays map of logging travel.
