Specifically for the Apple watch, people did with the original, but the newest model has enough battery to survive longer than 24 hours. I sleep with mine on for (3rd party) sleep tracking and charge it while I'm in the shower.
interesting, does it charge fast enough so it holds the charge until the next shower?
I got my girlfriend an Apple Watch S1 which is usually at around 50-60% in the evening, but she always charges overnight and my feeling was that the inductive charging is rather slow.
Sometimes not if I'm quick or it's been used for exercise tracking the day before, but by "shower" I really mean "morning routine". Take it off when I get out of bed and then put it on as I leave the house for work. It's always at 100% in that case, and I'd guess it's usually charging for 45 minutes to an hour.
