That's right, a watch that does literally nothing but tell the time lasts a long time on a single battery charge. If having to charge your watch is not worth the benefits/luxuries provided by an expensive smartwatch, a smartwatch might not be for you.
To give a quick summary: I look at the upcoming weather, see the times of upcoming meetings, see messages people have sent me, pause/resume/skip tracks on currently-playing music, track hikes or walks, record audio, check my heart rate, check the current time/date, and pay for stuff.
