Apple is now selling Watch Series 9 and Ultra 2 with disabled blood oxygen monitor
 

If you're in the US, any Watch Series 9 or Ultra 2 model you buy from Apple will no longer have a functional blood oxygen monitoring feature. Apple failed to convince the court to allow it to keep selling the aforementioned models while it's appealing a ruling by the US International Trade Commission (ITC). If you'll recall, the commission found that Apple had violated patents owned by medical technology company Masimo, which accused the iPhone-maker of infringing on its intellectual properties related to light-based blood-oxygen monitoring. The ITC ordered the company to stop selling the contested watches.
