Sorry to hear about your watch problems. The GH-625M has an IPX7 rating, so running in the rain shouldn't be a problem. If moisture leaked into the display area, then there might be a compromise on the seal around the display. How long have you had the GH-625M? And where did you purchase it from? It might be covered under warranty, if you purchased it from an authorized reseller & it was purchased within a year. If it's not, then your best bet would be use the blow dryer and the sun and see if that helps revive your watch.
