Casio G-Shock Octagon Quartz Black Dial Resin Strap Men's Watch GA-2100-1A3ER
The Casio G-Shock GA-2100-1A3 combines rugged durability with sleek urban style, a watch built for everyday wear, sport, and adventure without sacrificing contemporary design. Its octagonal carbon-resin case paired with a resin strap gives the watch a bold yet streamlined profile, while neon-accent details on the hands and dial add a fresh, modern flair.
Tough Build & Reliable Protection
Built with G-Shock’s Carbon Core Guard construction, the GA-2100-1A3 is shock-resistant and designed to withstand rough handling, making it ideal for travel, sports, outdoor adventures or simply everyday urban life. It also offers 200 metres (20 bar) water resistance, so it’s ready for swimming or heavy rain without worry.
Feature-Rich Quartz Movement & Everyday Utility
Under the hood, the GA-2100-1A3 runs on a quartz analogue-digital combination movement, offering a suite of useful functions: a 1/100-second stopwatch, countdown timer, 5 daily alarms, full auto-calendar, world time (31 time zones), dual LED illumination (both for the analogue face and digital display), and a 12/24-hour format option. The analogue hands are coated with phosphorescent paint, ensuring visibility in the dark.
Slim Profile & Everyday Wearability
Despite being a G-Shock, the GA-2100-1A3 is notably slim: the case measures roughly 48.5 × 45.4 × 11.8mm, and the watch weighs about 51g. Its relatively low thickness and lightweight build make it comfortable for daily wear, whether under a jacket, during active use, or casual outfits.
A Stylish, Functional All-Rounder
The GA-2100-1A3 doesn’t hide its toughness; it also expresses a bold, modern aesthetic. It works as a dependable sports watch, a robust outdoor companion, or a stylish urban timepiece. For someone wanting a watch that balances resilience, versatility, and contemporary style, this G-Shock hits the mark.
