I was always partial to my Timex watch.  I like the indiglo.

I'll admit I have a Garmin VivoSmart at the moment.  It was the only watch I could find that I could turn bluetooth and wifi off, but would do a decent job of tracking my sleep because I was having some significant sleep issues and wanted to figure things out.  I like being able to track sleep and steps, but I really miss my old Timex watch.  I might go back.

FYI, my garmin is linked to an email that isn't used for anything else, so it isn't tracking me like most smart watches.
