GST-S120L-1A is a G-STEEL analog-digital model featuring a stainless steel bezel layered over a resin case and paired with a black leather band for a refined yet durable construction. The black dial with metallic accents integrates a digital display within the multi-layered analog layout, delivering a balanced industrial aesthetic. Powered by Tough Solar, it converts light into energy for reliable performance. Built with shock resistance and 200-meter water resistance, it is suited for everyday and active wear. Mineral glass protects the dial, while confirmed functions include world time, stopwatch, countdown timer, daily alarms, and LED illumination for enhanced visibility in low-light conditions.
