Continuous Heart Rate
The Continuous Heart Rate feature measures your heart rate around the clock. It enables a more accurate measurement of daily calorie consumption and your overall activity because also physical activities with very little wrist movement, such as cycling, can be tracked.
Continuous Heart Rate on your watch
You can turn the Continuous heart rate feature on, off or to night-time only mode on your watch in Settings > General settings > Continuous HR tracking. If you choose Night-time only mode, set heart rate tracking to begin at the earliest time you might go to bed.
The feature is off by default. Keeping the Continuous Heart Rate feature on in your watch will drain the battery quicker. Continuous heart rate tracking needs to be enabled for Nightly Recharge to function. If you want to save battery and still use Nightly Recharge, set the continuous heart rate tracking to be on only at night.
In time view, use the UP and DOWN buttons to navigate to the heart rate watch face. Press OK to open a detailed view.

When the feature is on, the watch continuously measures your heart rate and displays it on the Heart rate watch face. When opening the details, you can check your highest and lowest heart rate readings of the day and also view what your lowest heart rate reading of the previous night was. The watch tracks your heart rate in 5-minute intervals and records the data for later analysis in the Flow app or web service. If the watch detects that your heart rate is elevated, it starts to record your heart rate continuously. Continuous recording can also start based on your wrist movements, for example, when you’re walking with a fast enough pace for at least one minute. The continuous recording of your heart rate stops automatically when your activity level drops low enough. When your watch detects that your arm is not moving or when your heart rate is not elevated it tracks your heart rate in 5-minute cycles to find your lowest reading of the day. In some cases, it is possible that you’ve seen a higher or lower heart rate on your watch during the day than is shown in the continuous heart rate summary as the highest or lowest reading of your day. This can happen if the reading you’ve seen falls outside the tracking interval.
