Product Details

Description

The Casio G-Shock GA-2100K-5AER is an analog-digital watch from the iconic GA-2100 series, inspired by music-driven nightlife. The design evokes the shadowy atmosphere of nightclubs and music festivals, with neon-coloured accents sparkling like laser light, while translucent materials with a matte finish on the bezel and strap deliver a distinctive texture. A newly developed surface finish gives the dial a clean, refined look with the rich depth of piano black.

The carbon and resin case with the proven Carbon Core Guard structure provides outstanding shock resistance and water resistance to 20 bar. The watch combines an analog two-hand dial with a digital display and offers a wide range of functions including world time, stopwatch, countdown timer and five daily alarms. Thanks to Neobrite luminous material and dual LED illumination, the GA-2100K-5AER remains clearly legible even in the dark.

Key Features of the Casio GA-2100K-5AER Watch

  • Carbon Core Guard Structure: Shock-resistant carbon and resin case with water resistance to 20 bar for maximum durability
  • Analog-Digital Combination: Two analog hands (hours, minutes) plus a digital display with world time, stopwatch and countdown timer
  • Neobrite and Dual LED: Luminous material on hands and indices plus Super Illuminator LED lighting for excellent legibility in the dark
