If I update my Apple Watch to OS 10.3, will it disable the blood oxygen sensor?
will Watch 10.3 update disable blood oxygen sensor on a watch series 8 purchased in Hong Kong?

No, it will not be disabled. The legal action only pertains to series 9 and Ultra models sold on or after 1/18/2024. Your series 8 is not involved in any of this. I updated my wife’s series 8 to watchOS 10.3 and the O2 feature continues to work as it always has.
