DAMN. I just did a little drop test with my 5600 E.....it failed the test....miserably. I stood at the top of my staircase, help the watch by the strap, and released it. It landed directly flush on its face, (just like in the drop test video on the casio website) and when I picked it up I knew something was wrong. No beeping when I hit the buttons, switched to 24hr mode, scrambled the year and everything else. I played around with it for a minute trying to get it back in order and the screen went dead. BOO!!! So much for the 10 meter drop resist.
