Soft urethane band for a comfortable fit

The band is made with soft urethane to ensure a highly comfortable fit on the wrist. Use of the same material for the band pieces on the underside helps reduce contact with the back of the hand for further enhanced comfort. The band surface features a non-slip texture for use around water and other situations. A band piece engraving features a silhouette of the RANGEMAN wild cat character.

Attention to materials: Bio-based resin

Key resin components of the bezel, case, and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.

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).

Mud Resist buttons to withstand harsh conditions with text

The buttons are protected by cylindrical stainless-steel parts, and the button shafts are equipped with gasket fittings to prevent contamination with mud and dust. Target mark-inspired notches provide anti-slip top surfaces. Designed with a passion to deliver utility enabling more reliable multifunction control in the most punishing conditions, from environments with abundant mud, dirt, sand, or rubble, to severe weather situations.

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.

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.

Metal side guards to endure hard use

Sizeable metal components guard the watch’s high-precision devices, including the module, sensors, and GPS antenna, from the shock of drops and other impacts. A forged metal button guard protects the main control button at the 9 o’clock position. The complex moulded form of the sensor cover at 3 o’clock is created with metal injection moulding (MIM), using finely powdered metal.

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.

Calculates VO2max (maximal oxygen uptake) during running.

*Running Index scores are calculated in RUN activities only.

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

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

Energy sources | Powered by POLAR® |
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® |
Analyse how well your body recovers overnight from exercise, overall stress, and other demands of your day.

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

Breathing exercises | Powered by POLAR® |
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.
