The thing with small phones (or pocket watches) is that they're still something that has to go in a pocket (or bag). For me, and I suspect many others, once I'm putting something in a pocket it might as well be more or less as large as it can be (while, in my case at least, being fairly usable with one hand). IMO the Plus models are a bit big for this but the iPhone X is just about perfect.
A watch OTOH is something that you can have right there for just about any activity and which can alert you even if a phone is tucked away someplace. I tend to also agree that AR, better conversational interfaces, etc. will probably make wearables more capable over time.

Some popular designer jeans can't fit anything much bigger than the SE into their front pockets. It might seem crazy, but the're people who buy the phone that fits into their favorite jeans vs. the other way round.
