Iconic Octagonal Design. Ultra-Slim Profile. Legendary G-Shock Toughness.

Experience the perfect combination of modern styling, advanced durability and reliable timekeeping with the Casio G-Shock GA2100-1A.

Part of the renowned G-Shock Carbon Core collection, this impressive analog-digital watch combines the brand's legendary shock-resistant construction with a sleek, minimalist design.

Inspired by the original G-Shock DW-5000C introduced in 1983, the GA2100-1A features the distinctive octagonal bezel that has become one of the most recognisable designs in the G-Shock collection.

Its bold black resin case and matching strap create a versatile, contemporary appearance that looks equally impressive with casual clothing, sportswear and everyday outfits.

Iconic Octagonal Styling with a Slim Profile

The Casio GA2100-1A stands out with its distinctive eight-sided bezel, clean dial layout and streamlined construction.

Despite its rugged design, the watch measures just 11.8mm thick, giving it a surprisingly slim profile compared with many traditional G-Shock models.

This carefully balanced design makes the GA2100-1A comfortable for everyday wear while maintaining the durability expected from a G-Shock.

The combination analog-digital display features bold hands, a convenient day indicator and a practical digital screen.

Neobrite luminous detailing helps improve the visibility of the analog hands in low-light conditions.

Whether you're heading to work, enjoying a weekend adventure or looking for a stylish everyday watch, the GA2100-1A offers a timeless sporty appearance.

Advanced Carbon Core Guard Technology

At the heart of the GA2100-1A is Casio's innovative Carbon Core Guard structure.

This advanced construction uses a high-strength resin case reinforced with carbon fibres to protect the watch's internal module.

The carbon-reinforced structure provides excellent strength and resistance to impacts while allowing the case to remain lightweight and slim.

Combined with G-Shock's legendary shock-resistant design, the GA2100-1A is built to withstand the demands of active lifestyles and everyday adventures.

The durable mineral glass helps protect the dial, while the flexible resin strap provides a comfortable and secure fit.

200M Water Resistance – Ready for Adventure

Designed to keep up with your lifestyle, the Casio G-Shock GA2100-1A offers impressive 200-metre water resistance.

Suitable for swimming, snorkelling and a wide range of water-based activities, this rugged timepiece provides dependable protection against water exposure.

Whether you're enjoying outdoor adventures, travelling or simply looking for a durable everyday watch, the GA2100-1A delivers reliable performance in demanding environments.

Practical Analog-Digital Functionality

The GA2100-1A combines the classic appearance of an analog watch with the convenience of modern digital features.

Its world time function covers 31 time zones, including 48 cities and Coordinated Universal Time, making it a practical companion for international travel.

A precise 1/100-second stopwatch allows you to measure elapsed time, split times and first- and second-place finishes.

The countdown timer can be set for periods of up to 24 hours, making it useful for workouts, sports activities and everyday tasks.

Five daily alarms and an optional hourly time signal help you stay organised throughout the day.

Double LED Super Illuminator

For convenient visibility in dark environments, the GA2100-1A features a double LED lighting system.

The Super Illuminator provides dedicated illumination for both the analog dial and the digital display, with selectable illumination duration and afterglow.

The convenient hand shift function temporarily moves the analog hands away from the digital display, making it easier to read important information.

Additional features include a full automatic calendar programmed until 2099, selectable 12/24-hour time format and the option to mute button operation sounds.

Powered by reliable quartz movement with an approximate three-year battery life, this versatile watch delivers dependable performance with minimal maintenance.
