Hello all! I've just wanted to ask you. In 1985 my parents bought me in London a watch of Casio which I'm not sure if it's a G-Shock or not. I wonder if you could tell me which model it was. Here is the picture, it's got 2 coarse buttons in the bottom and 2 in the left side (the top one is for adjust). It got a blue circle in the right with the seconds inside of it.
Thanks a lot!
