This is a counterfeit variant mimicking the premium Casio G-Shock GM-2100B-3A “CasiOak” Metal Series design.

Materials: Low-grade alloy or chrome-plated plastic bezel instead of true forged stainless steel.

Build: Basic silicone or cheap plastic strap that mimics the textured green resin band.

Internals: Cheap, generic quartz movement replacing the authentic multi-functional Casio module.

Durability: Lacks genuine G-Shock shock-proof engineering and has minimal to no water resistance.
