Carbon Core Guard Technology
The reinforced Carbon Core Guard structure combines carbon fibre with high-performance resin to provide exceptional impact resistance while significantly reducing weight. This advanced construction allows the GA-2100CM-8AER to remain remarkably slim without compromising durability.
Both the case and strap are manufactured using bio-based resin, helping reduce environmental impact while maintaining the strength and flexibility G-SHOCK is known for.
Analogue & Digital Performance
The large analogue hands provide excellent readability, while the digital display offers instant access to advanced functions including World Time, stopwatch, countdown timer and calendar. The convenient Hand Shift feature temporarily moves the hands away from the display whenever additional visibility is required.
Designed for Everyday Adventure
The watch includes five independent daily alarms, a fully automatic calendar, selectable 12- or 24-hour time format and the ability to mute button operation tones without affecting alarms or timer notifications.
The integrated stopwatch measures elapsed time, split times and final times for up to 24 hours, while the countdown timer can be programmed from one second up to 24 hours, making it ideal for sports training and everyday time management.

Protected by scratch-resistant mineral crystal and featuring luminous hands for improved visibility in low light, the GA-2100CM-8AER is built for demanding conditions. Its 200-metre water resistance makes it suitable for swimming, snorkelling and a wide range of water sports.
