GAX-100MB-4A is a G-LIDE surf-inspired G-SHOCK featuring a red resin case paired with a matching red resin strap for a bold, sporty construction. The analog-digital display is set against a dark dial with large hands and markers designed for clear readability during outdoor and water activities. Built with shock resistance and 200-meter water resistance, it is well suited for active marine environments. Equipped with tide graph and moon data functions, it supports surf and ocean condition tracking. Mineral glass protects the dial, while confirmed features include world time, stopwatch, countdown timer, daily alarms, and an LED light for improved visibility in low-light conditions.
