Casio G-Shock Classic Watch GA-B2100-2AER

Introducing the Casio G-Shock GA-B2100-2AER, the connected evolution of the iconic GA-2100. This version stands out for its elegant chromatic combination: octagonal case in matte blue resin with textured finish, deep anthracite grey dial and luminescent white hands that contrast perfectly. The small digital display at 3 o'clock shows complementary information, while rectangular metallic grey hour markers define a modern and functional aesthetic.

At its heart beats the Casio module 5689, an analog-digital caliber with Tough Solar technology and Bluetooth connectivity. The display shows day, date and secondary time zone, while connected functions include automatic time synchronization, smartphone alarm setting, phone finder and notifications. It offers world time with 300 cities, 1/100 second stopwatch, countdown timer, 5 daily alarms and automatic calendar until 2099.

Born in 1983 from the challenge of creating an unbreakable watch, G-Shock revolutionized watchmaking with its resistance tests from 10 meters height. The Carbon Core Guard structure combines carbon fiber with resin, offering maximum protection in a surprisingly thin design. Tough Solar technology converts any light source into energy, ensuring continuous operation.
