Heart Rate Features

The Lily 2 watch enables you to view wrist-based heart rate data.

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.

Alerts you when your heart rate exceeds or drops below a certain number of beats per minute after a period of inactivity.

Monitors the 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.

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.

Displays your current VO2 max., which is an indication of athletic performance and should increase as your level of fitness improves.
