## Product: Apple Watch Series 9 (Renewed)
**Brand:** Apple

Yep, the Apple Watch Series 9 does have blood oxygen monitoring. Our research shows that it comes with a built-in sensor for checking your blood oxygen levels right from your wrist. It's a handy feature for keeping tabs on your respiratory and heart health.

Apart from that, the watch packs a bunch of other health tracking capabilities like heart rate monitoring and fall detection. According to the manufacturer's product description, it works best with [iPhones XS](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3DiPhones%2BXS%26tag%3Dssw.ans.tx-1-20) and newer. This compatibility makes sure all the watch's advanced features run smoothly.

Keep in mind, though, for the blood oxygen monitoring (and other cool features) to work properly, you need to pair it with one of those newer iPhones. If you try using it with an older model, you might face some connectivity issues.

Our data suggests folks generally find the blood oxygen monitoring accurate and user-friendly. 

But just make sure your iPhone's compatible before hopping in—it could save you from dealing with any frustrating tech hiccups and helps you get the most out of the watch's health tracking capabilities.
