Casio G-Shock Watch (Official Japanese Product) Full Metal Chronograph with Bluetooth and Tough Solar, GMC-B2100D-1AJF, Men’s, Silver

This analog “2100” series full-metal chronograph inherits the concept of the original G-SHOCK model, the DW-5000C. While the case, bezel, and band are made of stainless steel, it also retains the octagonal bezel shape and dimpled band design from the DW-5000C, which debuted in 1983. A fine resin buffer between the bezel and case ensures shock resistance even with a metal exterior. The bezel is crafted into a three-dimensional shape through time-consuming forging, cutting, and polishing processes, with a beautiful finish on the top surface with a circumferential hairline and a mirror-polished bevel. The indices and subdial ring are delicately crafted using micro-machining technology and finished with vapor deposition for a high-quality texture. The screw-lock crown shares the same octagonal shape as the bezel, contributing to the watch’s compact size while maintaining its shock resistance. High-density implementation technology allows for a slim, highly functional module, achieving a slim profile. Comfort is also a key consideration. Connecting to a dedicated app via Bluetooth® communication, this watch obtains time information and keeps accurate time. It also features practical features such as Tough Solar and a high-brightness LED light.
