Measure the intensity of your
exercise in real time
Heart Rate Measurement Functionality
Dedicated heart rate watch face
The watch face used in these models links up with the heart rate measurement functionality. When the internal accelerometer detects motion (walking, running, or cycling), measurement begins automatically.
Measure your VO2 max
Measure your maximum oxygen consumption for your body per minute (for each kilogram of body weight). You can use this as a guide for endurance activities, such as running.
Heart rate zone display
In addition to your current heart rate and the maximum and minimum heart rate for that day, display your exercise intensity in the form of your heart rate zone over ﬁve different levels. Enjoy activities or training without overexerting yourself.
GPS + Color Map Display
Current location display
Display your current position and your recorded movement log on a high-deﬁnition color map while you measure your activity. This allows you to check your current position without having to get out your smartphone. Use this feature in situations such as when you want to challenge yourself with new courses or when you want to run while traveling.
Import GPS log data (such as for past routes or recommended routes from ViewRanger) into the watch by using Google DriveTM, and set these routes for running. Check your route on the map while you run as a form of simple navigation.
Creation of original routes
Save the routes on which you travel during your activities as activity data. You can use markers to record checkpoints for locations such as places where water is available, and create your own running routes. You can then share these routes with others.
