Aesthetically, the collaboration timepiece features an off-white resin case and strap that feels modern, sporty, and fun. Bursts of bright colors indicate functionality; sunshine yellow for the Mode and Start/Stop indicators and tangerine orange for the Adjust and Split/Reset indicators. The G-SHOCK text at the top of the watch is a pleasing shade of periwinkle, adding a nice pop of color to the overall design. And what about the legendary "Triple Graph" display? Each of the three registers are circled in one of red, green, or grey. The best part is that all the colors used on G-SHOCK Ref. 6900-PT80 come directly from the original PT-80 keyboard.
