G-SHOCK's GLX-5600 series supports extreme sports and is worn by some of the world's top surfers. The thin, compact and highly wearable DW-5600 is used as the base model and the new 'RT' collection is equipped with a tide graph, 3 alarms, an auto EL light and an auto repeat countdown timer. The metal dial and the mirror-finished tide graph display lends a stylish finish to an already practical, sporty and summer-ready timepiece. The GLX-5600RT-9ER is a sunny yellow hue with a white LCD.
