Black G-shock watch GMA-P2100BB-1ACR

The Casio GMA-P2100BB-1ACR is a compact, all-black interpretation of the iconic “CasiOak” design, built for a clean and minimalist street-style aesthetic.

Featuring a matte black resin case and strap, it delivers a bold monochromatic look that emphasizes shape and texture over color. The octagonal bezel design keeps the signature G-SHOCK identity intact, while the slightly smaller GMA-P form factor ensures a lighter, more comfortable fit on the wrist compared to standard 2100 models. It uses a durable bio-based resin construction, reinforcing Casio’s focus on both toughness and reduced environmental impact.  

Functionally, the watch offers 200-meter water resistance and full shock protection, along with everyday essentials such as world time, stopwatch, countdown timer, multiple alarms, and a bright double LED light for visibility in low-light conditions. The analog-digital layout also includes a hand-shift function for unobstructed reading of the digital display.  

Overall, the GMA-P2100BB-1ACR is ideal if you want a stealthy, modern G-SHOCK that prioritizes simplicity, durability, and a smaller, more wearable profile without losing the classic 2100 design language.
