Re: Benefits?
If you only want to know the time, a smartwatch offers no advantages. If you want very simple notifications and handy features like being able to page your phone if it's fallen between sofa cushions, then there are smart watches from Casio and Citizen that have very good battery lives - months. If you want a watch that is also a GPS tracker, means of payment, runs apps, maps and makes calls - then yeah, the downsides such as bulk and poor battery life may make themselves noticed.
All design and engineering is a process of compromise.
