"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.
Yes. Every modlab Casioak starts with an authentic Casio GA-2100, then we replace the case, bezel, dial, hands, and strap by hand in our Detroit workshop. The original G-Shock movement, water resistance, and shock protection all stay intact.
Case 45.4 mm × 48.5 mm × 11.8 mm. Strap fits 5.5"–8.5" wrists. Total weight ~52 g. Uses a standard 22 mm strap, easily swappable.
Yes — pick from our Classic, BeSpoke, and Signature series. Classic is a sleek case + bezel upgrade; BeSpoke lets you mix-and-match every component; Signature uses sapphire glass and a Japanese-copper dial for the highest-end build.
