I'm in the US and I totally forgot about the blood oxygen patent fiasco. I have an Apple Watch Series 8 and it continues to work. Maybe it's only newer models that are affected?

(Aha, this article says it's Series 9 and Ultra 2 that are affected: <https://www.tomsguide.com/wellness/smartwatches/apple-wins-p...>.)
