G-Shock Full Metal Watch. GMCB2100D-1A - The "Full Metal" Silver Oak

The GM-B2100D-1A is a study in Brutalist Elegance. Unlike the "Metal-Covered" (GM) series, this is a Full Metal Construction—every exterior component, from the octagonal bezel to the integrated bracelet and the inner screw-back case, is crafted from solid stainless steel. It features a sophisticated multi-finish: a sharp vertical hairline brush on the top of the bezel and mirror-polished facets on the sides that catch the light like a cut diamond.

The dial is a monochrome masterpiece, featuring a silver vapor-deposition finish on the dimensional indexes, creating a high-contrast "Steel-on-Steel" aesthetic that feels both industrial and incredibly refined.

Key Performance Features

Full Stainless Steel Construction: A solid metal bracelet and case that provide a heavy, premium weight (165g) and a "Luxury Integrated Bracelet" feel.

Screw-Back Case Construction: Features a solid steel inner housing with a DLC-coated (Diamond-Like Carbon) screw-down back, ensuring the highest level of structural integrity.

Smartphone Link (Bluetooth®): Pairs with the G-SHOCK app for automatic time adjustment, "Phone Finder" function, and easy setting of world time for 300+ cities.

Tough Solar Power: High-capacity solar panels integrated into the dial ensure the high-torque analog motors and Bluetooth functions never run out of juice.

Ultra-Slim Profile: Despite the massive full-metal screw-back construction, it maintains a remarkably slim 12.8 mm profile, making it the most "Shirt-Sleeve Friendly" G-SHOCK in the catalog.

Fine Resin Buffer: A specialized resin cushioning layer between the metal bezel and the inner case ensures the watch meets G-SHOCK’s elite shock-resistance standards.

200m Water Resistance: Fully professional-grade protection—this "Silver Suit" is built for the ocean or the office.
