That's a cool picture:-! , the one on the bottem right (5700) with the golden buttons was my first G-shock which i bought in 1989 -1990 on a dutch navy base on Curacoa. Gave it away to a good friend which wanted the same watch but coldn't buy it anymore.This is a vintage Ad's of casio G-shock featuring some grael model... I've find in abandoned japanese fashion magazine called: BOON
Nice that you have gave your watch to a friend!!!
