I have had this watch for just over a month and it is completely dead. How do I know I've had it for just over a month? Because I seem to have just missed the window to return it. I am still trying to find a way to do so because there is absolutely no way this watch should be dead already - I only wore it to go running a few times a week and it never got wet other than a few drops of my sweat and it sat on a dry counter the rest of the time. I will replace the battery if I can't return the watch, but that will cost about as much as the actual watch and be a pain in the butt and I'm not convinced that it won't just fry a new battery in a month too. I read many positive reviews of this product before purchasing it, so I was surprised it turned out so crappy. It is totally possible I just got a lemon and it is a fine product most of the time, but I thought I should share my experience as I've never had even a cheap watch like this die so quickly.
