Casio G-Shock Classic Watch GBM-2100A-8BER

Introducing the Casio G-Shock GBM-2100A-8BER, a sophisticated evolution of the legendary GA-2100 that combines advanced technology with refined design. The octagonal case features a striking metallic silver finish with brushed texture that elegantly contrasts with the light gray dial displaying horizontal geometric patterns. Black rectangular indices mark the main hours, while a small analog subdial at 9 o'clock shows additional information. The triangular digital display at 3 o'clock exhibits data like alarms and signals, complementing the robust black hands with luminescent tips. The black textile strap with woven texture provides comfort and a contemporary touch.

At its heart beats the advanced Casio module 5729, integrating Bluetooth connectivity for automatic smartphone synchronization, Tough Solar technology for light-powered charging, and complete world time functions. The analog subdial can display different configurable parameters, while the digital display offers 1/100-second stopwatch, five daily alarms, automatic calendar to 2099, and phone finder function. Bluetooth connection enables automatic time adjustment and function configuration through the G-Shock Connected app.

The G-Shock series was born in 1983 from engineer Kikuo Ibe's dream of creating an unbreakable watch. After more than 200 prototypes and drop tests from 10 meters high, a legend was born that has withstood earthquakes, space missions, and the wrists of explorers in the most extreme corners of the planet. The 2100 line represents the most elegant evolution of this philosophy, maintaining legendary resistance in a more refined and connected format.
