The first thing to understand is that the Apple Watch has multiple ways of checking your heart rate. The most common method is through the use of green LED light and a photodiode, which are located on the back of the watch. When the watch is worn, the LED light shines onto the skin, and the photodiode measures the amount of light that is reflected back. This is known as photoplethysmography (PPG), which is the same technology used in pulse oximeters.
The Apple Watch also has an ECG sensor, which can be used to measure your heart rate by detecting the electrical signals of your heart. This sensor is located on the back of the watch and can be used to take an electrocardiogram (ECG) reading.

When it comes to the frequency at which the Apple Watch checks your heart rate, there are a few factors to consider. The watch uses a combination of both PPG and ECG sensors to check your heart rate. By default, the watch uses the PPG sensor to check your heart rate every ten minutes. This means that if you are wearing the watch and not doing any activity that would increase your heart rate, such as exercise, the watch will check your heart rate every ten minutes.
However, if you are doing an activity that increases your heart rate, such as exercising, the watch will check your heart rate more frequently. This is done to provide more accurate and detailed information about your heart rate during exercise. The watch will also check your heart rate more frequently when you are using certain features, such as the Heart Rate app or the Workout app.

In summary, the Apple Watch checks your heart rate using a combination of PPG and ECG sensors. By default, the watch uses the PPG sensor to check your heart rate every ten minutes, but it will check your heart rate more frequently if you are exercising or using certain features. You can also enable the “Heart Rate Notifications” feature to be notified when your heart rate goes above or below a certain threshold, which allows you to keep an eye on your heart rate throughout the day.
