Casio G-Shock Watch GA-2100CA-8AER

Introducing the Casio G-Shock GA-2100CA-8AER, one of the most striking variants of the legendary GA-2100. This grey with camouflage dial version stands out with its camouflage gris urban dial and resin gris dark strap, creating an ensemble that demands attention.

Inside beats the Casio module 5611, an analog-digital caliber combining three hands for the main reading with a compact digital display at 3 o'clock. This display shows the day of the week, date, and a secondary time zone. The watch offers world time across 31 time zones (48 cities), a 1/100-second stopwatch, countdown timer, 5 daily alarms, and auto-calendar until 2099.

The Carbon Core Guard structure is the key innovation of the GA-2100: a carbon fiber inner case that shields the module from impacts while drastically reducing weight. At just 51 grams and 11.8 mm thick, this G-Shock feels as comfortable as a dress watch but delivers the legendary toughness of the series.

G-Shock was born in 1983 with one goal: to create an unbreakable watch. Over 40 years later, every G-Shock still passes free-fall tests from 10 meters, centrifuge and water pressure tests. The GA-2100 is the modern evolution of that philosophy: thinner, lighter, but equally indestructible.
