Until I started wearing the watch to workout. Before, I was wearing a case on it, but the case wasn't that good, so I started going without. After the 2nd run without it, I started getting some of that slowed crown movement that I've read about. I've read the solution to that is to let water run into that area, but there's some sweat on the watch at that point too. It just seems so much more convenient to jump in the shower and clean everything at once, even if it does make cleaning your wrist slightly more complicated.
