## Long description

G-SHOCK GA-2100-1A4ER is a quartz wrist watch with a carbon-reinforced resin case and a black finish. Designed for everyday wear, the watch combines shock-resistant construction with a compact profile — case diameter 48.5 mm, depth 45.4 mm and thickness 11.8 mm — and offers reliable timekeeping with an estimated battery life of approximately three years. The dial is protected by mineral glass and features LED illumination and a Neo-display for enhanced visibility in low light. Water resistance up to 20 bar makes the model suitable for water activities without scuba gear.
Advantages
The carbon-reinforced resin case increases impact resistance while keeping overall weight low, and the mineral glass provides scratch resistance for long-term durability. Integrated functions such as world time, stopwatch, countdown timer, five daily alarms and a fully automatic calendar deliver practical everyday utility. Additional convenience features include a hand moving function for unobstructed view of digital displays, selectable button tones and LED illumination with long-lasting luminescence.
