The Casio G-Shock Watch has a built-in calculator and digital display, plus it stores numbers and keeps track of the date for you (so you don’t miss that ever-important dinner rendezvous). While keeping you in the good graces of your object of desire, the G-Shock also ensures that you’re the perfect picture of retro accessorizing.
