The Watch is very much a companion product & essentially the AR glasses will NEVER replace the physical device that you hold in your hand.
Currently "The Watch is very much a companion product" yet it will evolve.

Reaons for my hypothesis:
More of a personal product, and more fashionable (both the watch and a potential excellent AR glasses with prescription and tinting and polarization). For centuries each product is used by those that require it or not.
AR Glasses solves the issue for those that:
a) Don't want large screens
b) Want large screens to display more (AR glasses)
c) foldable phones are a joke; longevity with more mechanical moving parts = less longevity.
d) You don't really drop your watch often do you?
e) no need for that 'blackberry helmet' jokingly, yet seriously people still stare at their phones while walking or crossing the street in public - still a hazard.
f) distracted driving can be nullified or heavily reduced.
g) (speaking of F) ... Aston Martin has the AMR concept hypercar in development and their centre console is using your smartphone - and an app - NOT a dedicated console; thereby reducing costs: no need for large screen by manufacturer, no need for LTE data for the car - use your mobile carriers via your phone.
