Apple Seeds Release Candidate Version of watchOS 10.3

Apple today seeded the release candidate version of the upcoming watchOS 10.3 update to developers and public beta testers, with the beta coming a week after the release of the third watchOS 10.3 beta. The release candidate represents the final version of watchOS 10.3 that will be provided to the public next week when watchOS 10.3 launches.

Apple Watch Faces watchOS 10 Feature Blue
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.

Once beta updates have been activated, watchOS 10.3 can be downloaded under the same Software Update section. To install software, an Apple Watch needs to have 50 percent battery life and it must be placed on an Apple Watch charger.

There's no word yet on the new features that might be included in watchOS 10.3 beyond a new Unity Bloom watch face, and no notable new features were found during the beta testing process.

Full release notes are below:

watchOS 10.3 includes new features, improvements, and bug fixes, including new Unity Bloom watch face to honor Black history and culture in celebration of Black History Month.

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.
