Any thoughts on this one? After A day of swimming in the cold Maine ocean, my riseman's screen went blank. Nothing. No pressing of buttons would do anything. The only sign of life was a minuscule flashing "C" in the lower left corner. Convinced it was dead and likely flooded, I almost threw it away and thought I had my excuse for a 7900. An hour later, it came back to life. Running like it always was. Never lost a second. 24 hours later and it's still good. No condensation or any signs of water damage.
I checked a couple of times during the course of the day while swimming. There was never visible signs of water entry. I'm active and this watch is always outside. It hasn't left the high charge mark since the first month I had it. Oh yeah., it's about a year and a half old.
