Table of Contents

The watch has a wrist-based heart rate monitor and is also compatible with chest heart rate monitors. You

can view heart rate data on the heart rate glance. If both wrist-based heart rate and chest heart rate data are

available, your watch uses the chest heart rate data.

There are several heart rate-related features available in the default glance loop.

Your current heart rate in beats per minute (bpm). There is graph of your heart rate for the last four hours,

highlighting your highest and lowest heart rate.

Your current stress level. The watch measures your heart rate variability while you are inactive to

estimate your stress level. A lower number indicates a lower stress level.

Your current Body Battery energy level. The watch calculates your current energy reserves based on

sleep, stress, and activity data. A higher number indicates a higher energy reserve.

The current saturation of oxygen in your blood. Knowing your oxygen saturation can help you determine

how your body is adapting to exercise and stress.

NOTE: The pulse oximeter sensor is located on the back of the watch.
