Apple has just seeded beta 5 of watchOS 8 and tvOS 15 to registered developers. Both are available to download over the air.

We are just a few weeks away from being treated to new hardware from Apple, including new iPhones. But alongside that, new software will be released to compliment said hardware. And two of the software releases everyone should look forward to right now is watchOS 8 and tvOS 15. Both in beta currently, you can download the fifth pre-release version right now if you are a registered developer with Apple. It is super easy to download as long as you have a previous beta installed onto your device.
