Casio G-Shock GA-2100AS-5AER – Rugged Strength Meets Minimalist Style

The Casio G-Shock GA-2100AS-5AER is part of the iconic G-Shock Classic line, renowned for its unmatched toughness and distinctive design. This model pairs a modern matte beige case with a deep blue dial, creating a striking contrast that works as well in the city as it does outdoors. Its octagonal bezel—an homage to the original 1983 G-Shock—adds a subtle retro edge to its contemporary silhouette.

Constructed from carbon-reinforced resin, the 45 mm case is lightweight yet incredibly durable, offering superior resistance to shocks and external impacts. The fixed bezel and screw-down stainless steel case back reinforce the watch’s rugged build. Hardened mineral glass protects the dial from scratches, while luminous hands and indexes, paired with an LED backlight, ensure clear readability day or night.

Inside, a precise quartz movement delivers both analogue and digital timekeeping. The GA-2100AS-5AER comes equipped with a full suite of practical features, including 12/24-hour display, world time, alarm, stopwatch, countdown timer, date, month, year display, and an automatic calendar—making it as functional as it is stylish. With 200 m water resistance, it’s ready for any adventure, from daily wear to swimming and water sports.
