Yes your smartwatch has a heartrate sensor.
You will want to assign Heart Rate to one of your watch face’s complications from the brand watch app options.
Your BPM reading will automatically update every twenty minutes after the first reading, or you can prompt a reading at any time by tapping the icon. You will see dashes on your screen after tapping the heart rate icon. It can take 10-15 seconds to capture a reading. If the sensors have trouble capturing your heart rate, the smartwatch will walk you back through wear recommendations.
