screen on watch is dark, put it on charger, voice from watch says 100% charged then says time.
Screen on watch is dark, can't get it back on. Put it on charge, voice from watch says 100% charged then announces time. Pressing either button doesn't do anything. Pressing and holding both buttons for 10+ seconds and the apple logo appears on screen, stays on for a short while, announces "screen curtain on", then says 100% charged. Did not drop or bang it, just started while on charger. Any suggestions?
Apple Watch, purchased new April 2015
