I bought a Garmin 610 last year and love it, but the coating on the back of the watch (part that lies against the wrist) has developed a bunch of tiny bubbles. kind of like a bumpy asphalt road. It actually caused cuts on my wrist due to the protrusions sliding back and forth against my wrist. I started wearing a Band-Aid under the watch, and that solves the problem.
Anyone else experience this problem? Not quite what I expected out of a $400 watch.
