I found a solution.
Apple sent me a brand new SE gen 1. The old one was just returned in the same box.
Turn off automatic system updates on the Apple iPhone Watch App.
Keep the OS that came with the watch 9. something.
DON'T UPDATE!!!
Maybe 6 months from now I'll update.
Also, make sure you turn off App mirroring and de install any 3rd party apps that automatically install while setting up.
I got a brand new SE gen 1 out of the deal. Battery health is 100% and should last another 2 years like my last one did.
Solved for now.
