To install the ‌watchOS 10.3‌ update, developers will need to open the Apple Watch app, go to the Software Update section under "General" in Settings, and toggle on the watchOS 10 Developer Beta. An Apple ID linked to a developer account is required.

Even if they don't remove it in this RC build 21S644 - suppose they make a public release with build 21S645 removing O2 monitoring on ALL apple watches in ALL countries!

Then don't update the watch at all!

Go to apple store asking for refund telling them you bought the apple watch for O2 functionality (even if you didn't).

If they say no, this opens them up to a whole lot more legal trouble because consumer protection legislation in many countries stipulate that if a device does not function as advertised then you are in fact entitled to a FULL REFUND.
