I had a nsfw thought so am putting my phone down

I sometimes put mine on a bicep band for workouts. If I’m going on a run I track the run itself with a Garmin watch (I prefer Garmin for sports tracking but Apple Watch for day to day smartwatch) and the Apple Watch is there for Apple Music, an emergency phone, and things like that. It works perfectly well on my upper arm. I wouldn’t want to wear it there day to day though since it is hard to see the display or navigate the watch’s UI but for a workout where once I start the music I don’t have to do much with it it works.

That said, in your case I’d go with something simpler. The Apple Watch seems like overkill for what you want it to do.

Yeah you should be able to wear it like a bicep cuff

The higher location may impact your health stats reporting heart rate, breathing assuming it’s over clothing but should still work

You can try. For some people it works well, for others not.

I’m sure someone makes an arm strap for the Watch. That said, if you don’t care for the smartwatch features, ecosystem integration, or having it on your wrist, why don’t you just get something else?
