A Refined Take on the CasiOak Design

The GBM-2100A-2BDR builds upon the hugely popular GA-2100 series, elevating it with a stainless steel bezel that adds both durability and sophistication. The octagonal case maintains its slim, modern profile while giving the watch a stronger, more luxurious wrist presence.

Its deep blue dial paired with a matching resin strap creates a bold yet tasteful color combination. For watch enthusiasts who appreciate sporty watches with a touch of elegance, this model strikes an ideal balance between rugged utility and everyday style.

Despite the metal bezel, the watch remains lightweight and comfortable—one of the defining strengths of the CasiOak lineup.

Built with True G-Shock Toughness

As expected from any G-Shock, the Casio G-Shock GBM-2100A-2BDR is engineered for extreme durability. The shock-resistant carbon core guard structure protects the internal module against impacts, making it suitable for active lifestyles and harsh environments.

This combination of metal and resin construction gives the GBM-2100A-2BDR a premium feel without sacrificing the toughness G-Shock is famous for.

Analog-Digital Display for Modern Enthusiasts

The analog-digital display is clean, legible, and thoughtfully designed. Bold hour markers and luminous hands ensure excellent visibility, while the digital display provides access to advanced features without cluttering the dial.

For watch enthusiasts who value functionality as much as aesthetics, this hybrid layout delivers the best of both worlds—classic analog style with digital precision.
