Can I have 2 Apple Watches (Series 8 and Ultra) and switch between them? If so, how would I do that?

Yes, you can pair more than one watch with your iPhone, but you can only use one watch at time.

That Support Article has been "Archived." I wonder why?🤔

I honestly don't know why it's been archived. To my knowledge, you can use more than one watch with an iPhone.
