Casio G-Shock Watch (Official Japanese Product) Full Metal Watch with Bluetooth, Tough Solar, Black Bezel, GM-B2100BT-1AJF, Men’s Silver

These models, inheriting the octagonal form of the original G-SHOCK model, the DW-5000C, feature a black octagonal top bezel. The black accents the silver, emphasizing the G-SHOCK’s iconic strength while creating a monotone design that easily complements a wide range of styles. The GMW-B5000BT features a mirror-finished top bezel and silver vapor deposition on portions of the glass, adding a sophisticated shine to its tough style. The GM-B2100BT and GMC-B2100BT feature a hairline finish on the top bezel, creating a sophisticated metallic look. Furthermore, for enhanced visibility, the indexes are silver vapor deposition, creating a striking contrast with the dial. The stainless steel bezel is beautifully crafted through painstaking processes including forging, cutting, and polishing, resulting in a three-dimensional shape. To achieve a full-metal shock-resistant construction, a fine resin buffer is implemented between the bezel and case. The metal band pieces are also dimpled, inheriting the resin band design of the original G-SHOCK. These watches are manufactured at Yamagata Casio, the mother factory that produced the original G-SHOCK. Furthermore, the stainless steel cases of the GMW-B5000BT and GM-B2100BT feature a highly airtight screw-back case.
