Do Galaxy smartwatches have SpO2?

As part of the plethora of health monitoring features available on Galaxy Watch3, this smartwatch is also able to track your blood oxygen levels via SpO2 measurements — checking the oxygen saturation in your blood

This works in conjunction with the Samsung Health app on your Galaxy phone, offering clear visuals to help you track your levels. Simply open the Samsung Health app on your Galaxy Watch3, and go to Stress, then tap Measure. Hold your finger on the sensor when it prompts you, and hold still to let the pulse oximeter work. When it's done, you'll get your results on your watch, and also on your phone.
