"Casioak" is the watch-community nickname for the Casio G-Shock GA-2100, blending "Casio" with "Royal Oak" — a nod to the Audemars Piguet luxury watch with the same octagonal bezel silhouette. The Casioak became a phenomenon thanks to its slim profile, accessible price, and how easy it is to customize into a luxury-feeling timepiece.
