Casio G-SHOCK Limited Watch GA-B2100BEG-1AER

Introducing the Casio G-SHOCK GA-B2100BEG-1AER, a limited edition GA-2100 that takes the total black aesthetic to a new dimension with neon green highlights throughout the dial. The octagonal resin case in matte black features the iconic eight-sided profile borrowed from high-end watchmaking, paired with a smooth black integrated resin strap. The all-dark dial contrasts sharply with silver luminescent main hands and dark grey minute markers around the bezel. At 9 o'clock, a dedicated Tough Solar charge indicator subdial stands out immediately, its slender neon green pointer moving against a concentric-ring background to display the current charge level. The central LCD display, backlit in green, constantly shows digital time, date, and active function indicators. The legends «TOUGH SOLAR» and «Bluetooth» are printed in green on the dial, making the watch's technological credentials visible at a glance. Side buttons labeled ADJUST, MODE, LIGHT and START complete a design that blends military utility with urban style.

Inside runs the Casio module 5689, a next-generation ana-digi caliber combining three-hand analog reading with a compact digital display. Bluetooth connectivity allows pairing with a smartphone via the G-SHOCK Connected app, automatically syncing the time anywhere in the world. Tough Solar charging delivers virtually unlimited autonomy under any light source. The module provides world time across 38 time zones and 300 cities, a 1/100-second stopwatch up to 24 hours, countdown timer, five daily alarms with hourly time signal, auto calendar programmed through 2099, power-saving function, and automatic analog hand synchronization with digital time.

G-SHOCK was born in 1983 from a Casio engineer's obsession with building the ultimate indestructible watch. After months of testing, dropping modules from heights of 10 meters, the G-SHOCK line launched and changed watchmaking forever. Four decades later, every G-SHOCK still undergoes the same rigorous tests for shock resistance, vibration, extreme temperature, and water pressure. The GA-B2100 family represents the natural evolution of the original GA-2100, adding solar power and Bluetooth connectivity without sacrificing a single millimeter of the ultra-slim profile that made the series iconic.
