Speaking of myself, I bought a Pebble watch back in 2013 or so. I quickly realized I liked wearing a watch. Then I also realized I really only needed the time function. I then went from the Pebble to a Seiko mechanical. Now I have no smart watches and about ten different mechanical and quartz watches.
The main reasons I prefer conventional watches: 1) They come in a much wider array of styles 2) They don't run out of power on long flights and leave you without your time reference right when you need it the most 3) They are generally cheaper 4) Some of them, like my Casios, have great features that work offline, like a digital compass, thermometer, altimeter ... all powered by solar! 5) To me (and this is a matter of personal preference) they look better 6) There are a lot of closet wristwatch nerds lurking in tech companies. Once you start wearing a Seiko mechanical, for example, you will soon get comments from other undercover watch nerds. I actually enjoy this random camaraderie.
