Smart Watch Monitors BLOOD OXYGEN, SLEEP, Heart Rate, Blood Pressure in Addition to Standard Fitness and Social Functions

I am asthmatic. I have been searching for smart watches that track oxygen levels and sleep. Most fitness watches are designed for those who are already fit! I need to monitor my blood oxygen in addition to pulse and blood pressure as I regain my health following mold induced asthmatic illness. With the help of fellow asthmatics, we have been testing oxygen monitors and smart watches. This is one that I use and recommend. It is compact and comfortable, even when exercising and sweating.
