Meet the G-Shock GA2100K-2A, a men's watch that pairs carbon-core guard resilience with a carbon and bio-based resin case and a bio-based resin band for a feather-light, durable feel. The case measures 48.5 × 45.4 × 11.8 mm and weighs 51 g, protected by mineral glass and a dial rendered in piano black with electric neon accents reminiscent of nightclub light. This analogue-digital timepiece delivers 31 world time zones, a 1/100-second stopwatch, five daily alarms, a 24-hour countdown timer and a double LED backlight for easy reading in any lighting. With 200 m water resistance and a battery life of about 3 years, it blends rugged performance with refined, contemporary style.
