I wouldn’t rely on the Apple Watch if you have a condition that needs oxygen monitoring. You’re better off buying a portable pulse oximeter and going to your doctor’s office and comparing its accuracy to your doctors WIRED meter that connects to a portable unit the nurses use. 

Some offices use the same battery operated ones that can be inaccurate. 

This along with blood sugar are readings you can’t get wrong because the consequences can be fatal. 

You’re more comfortable using a $10 pulse oximeter from Amazon that was probably made in the same factory that makes 1,000 other unrelated products?  Good luck to you.
