The Casio GA-900-1A watch is perfect for active people like athletes and adventurers. You can wear it while doing water sports thanks to its 200m water resistance, or when you're traveling around the world as it has world time feature. It's tough enough to handle shocks from any rough activities. The watch has a case size of 52.8mm × 49.5mm × 16.9mm and weighs just 65g, so it's not bulky to wear.
