A model equipped with a high-brightness LED backlight from G-SHOCK, which continues to evolve in the pursuit of toughness. Use of a high-brightness LED system and a light guide plate makes the watch easy to read even in the dark. It also has practical functions such as world time, an alarm, and a stopwatch. The color is classic G-SHOCK black, and the brand-color red is used as an accent throughout.
