Will Oxygen readings work in USA on Apple Watch 9 if purchased in UK?
Will Oxygen sensors work in USA, with an US Apple iCloud account, on Apple Watch 9 (or in a few months Series 10) if purchased in UK and brought into the US?
I plan to be in the UK this autumn, and was hoping to purchase the Series 9 (or 10 if available) in the UK. My Apple account is based on the USA location. Will the Oxygen sensor work for me when I return to the US?
Apple Watch Series 9
