How do I measure my heart rate?

Press the UP/DOWN button on the Watch Face screen to switch to the Heart Rate screen. The watch will automatically start heart rate measurement. Please wait until the watch's heart rate measurement is complete.
If All-Day Heart Rate is enabled, the watch periodically measures and records your heart rate data. The Heart Rate screen always displays the latest heart rate. Tap the SELECT key to start a single measurement.
You can view detailed heart rate data on the app.
