G-Shock Master Of G Land Rangeman GPRH1000-1D

Measurement functions to support active use in the field

Support for nine activities, including trekking. Functionality designed for outdoor use, with tide graph display capabilities, as well as direction, altitude, air pressure, and temperature measurements.

Trekking: Distance, time, pace, compass bearing, altitude, ascent and descent, heart rate, calories burned, etc.
Running, walking, trail running: Distance, speed, time, pace, heart rate, calories burned, etc.
Biking: Distance, speed, time, altitude, road gradient, heart rate, calories burned, etc.
Open water swimming, pool swimming: Distance, time, calories burned, etc.
Gym workouts, interval training: Time, heart rate, calories burned, etc.

6 sensors + GPS functionality to track movement in real time

Six sensors including a heart rate monitor accurately detect body movement as well as changes in the natural environment. The watch also includes built-in GPS functionality to measure position, distance, and speed of movement. Track a range of factors in real time while you're on the move.

Optical heart rate sensor: Uses LED light to measure changes in blood flow and track heart rate
Accelerometer: Analyses movement to measure activity such as number of steps taken
Gyroscope: Tracks swimming strokes and turns in the pool. Also helps with compass calibration.
Magnetic sensor, pressure sensor and thermo sensor: Tracks compass bearing, altitude/air pressure, and temperature. Accurately detects changes outdoors and in other environments.

Analysis functions for improving performance

Based on the body's data captured by the watch, your current performance and condition are displayed in an easy-to-understand format. This data analysis utilises algorithms from Polar, a company with a well-established reputation for heart rate-focused training analysis.

RUNNING INDEX | Powered by POLAR(R) |
Calculates VO2max (maximal oxygen uptake) during running.

*Running Index scores are calculated in RUN activities only.

Cardio load | Powered by POLAR(R) |
Understand how much strain your training session put on your cardiovascular.

Cardio load status | Powered by POLAR(R) |
Displays current training conditions based on cardio load data from past workouts.

Energy sources | Powered by POLAR(R) |
Calculates fats, carbohydrates, and proteins as percentages of calories burned.

Route travelled (App)
Displays routes travelled during activity on a map within the app.

Support functions: Helpful for self-management

Loaded with features helpful for monitoring recovery, managing health, and keeping track of logs. Easy-to-understand display of various forms of data in the app makes it simple to check daily activity logs, training status, and other information.

Nightly RechargeTM | Powered by POLAR(R) |
Analyse how well your body recovers overnight from exercise, overall stress, and other demands of your day.

*Nightly Recharge(TM) is a trademark owned by POLAR Electro Oy.

Breathing exercises | Powered by POLAR(R) |
Follow the animated display to maintain a steady rhythm of deep breathing.

Blood oxygen level measurement
The optical heart rate sensor tracks the level of oxygen taken into the blood.

*The blood oxygen level measurement function is not intended for use in diagnosing illness or as a medical device. It is intended only for use in maintaining general health.

Life log
Displays daily log of activity including number of steps and calories burned in an easy-to-understand format.

My Page (App)
Displays timelines of activity log, life log and other records.

Solar-assisted charging

Use USB charging for training functions such as GPS tracking and heart rate monitor, as well as smart functions such as notifications and step tracker. Time display is powered solely by solar charging, even when battery runs low.*

*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).
