Two to Four Weeks
A few days ago I think I ran and then swam. While waiting for lunch I noticed that the Garmin Forerunner 570 had a bit of plastic sticking out of it so I pulled on it, to see if it came loose. It didn’t. It stayed put. It appeared to come from between the case, and the screen. I suspect that it is part of the o-ring or adhesive mateerial that keeps the screen attached to the body of the watch that came loose.
