Description
The streamlined GA-2100 design features a carbon and resin case measuring 48.5 × 45.4 × 11.8 mm and weighs just 51 g. Built with G-SHOCK’s Carbon Core Guard structure, it delivers outstanding shock resistance alongside 200-metre water resistance, mineral glass, and Neobrite luminous coating for reliable performance day or night.
Packed with functionality, the GA2100K-5A offers world time across 31 time zones, a 1/100-second stopwatch, countdown timer, five daily alarms, and a full auto-calendar up to 2099. Double white LED illumination ensures clear visibility, while the hand-shift feature keeps the digital display unobstructed. Powered by dual SR726W batteries, it provides approximately three years of battery life with an accuracy of ±15 seconds per month.
A bold new take on the iconic GA-2100 — cutting-edge style infused with legendary G-SHOCK toughness.
