I used to have a wear OS 2.0 watch, you could actually pirate alot of watch faces for free using a loophole in the wear play store. Only works for Android phones.
-
Basically install an apk of the companion app for the watch face.
-
Then open the wear play store on your Watch and into owned apps, it will give you an option to install the watch face associated with the companion app installed on your connected phone.
-
Install the watch face, and there you go, you will even get updates as if you bought it.
Ofcourse it all depends on if someone archived an apk of the companion app or not. It's been a whole year too since my wear OS watch - a Huawei II Sport stopped working on me and I didn't bother to try to fix it, probably a battery issue. With Wear OS 3.0, Google may have patched it. Worth a shot though, if you have a 2.0 watch, should work.
Same method works for paid apps too pretty much.
I personally use Kodi with Seren and a Real Debrid sub(£15 for 6 months is great) .It's basically Netflix but has pretty much everything.
