Has this happened to anyone?

So I started a physical therapy regimen this week where I’m getting electrical stimulation therapy to my arms and legs. The first day when I got there I checked the time and everything was ok. That day they started my therapy on my legs- and when they were done my watch had this much condensation inside- he watch works fine but I can’t believe that having electrical currents pulsating through my legs could have cooked off this much moisture in my watch…
