No watches are not and unlikely to be redundant in the foreseeable future, they are just another choice in life.
don't like or need one? then don't wear one, however, there are still countless situations where watches are more appropriate/desirable/practical than a phone.
I wear a watch, I would feel like something was missing without it, i have grown up wearing one which is probably why.
Also for my job there are many situations where pulling out a phone is neither appropriate or practical, and a good tough watch is a necessity.
