Except for all the young, fit people that want to track their workouts and health. Maybe the time of watches that just tell time has passed - I would argue even against that with the continuing existence of Swiss luxury brands - but watch as a small health monitor is still in full force.
To be honest I usually wear a cheap Timex even though I have an Apple Watch because charging is a task. Wear for hiking. Care less about regular fitness tracking.
People that care about battery life probably use something more sporty like the new Suunto's (I get about 2weeks+ of batter life). However the smart watch health features are nowhere near as good.
