Casio G Shock G9300 Digital watch is very very useless watch. When I opened the watch and press the light button it works like reset button and when I press the reset button it works like light button. May be all buttons exchanged their places. Its battery life is also not good. I used the watch just one month its gone. The parts had came out of the watch. If it not works properly why to design this type of watches. Useless watch is this one only till I used watches. So dont buy this product guys.Thank you!
