Introducing a collection of new G-SHOCK models, whose 35mm diameter surfaces and large cases give an appearance of power and durability. The dial rings and raised hour markers create a three-dimensional depth that lends plenty of character to the dial. The popular G-SHOCK three-dial design incorporates an analog dial in the center, with digital dials on either side. These watches are designed and engineered to offer exceptional shock and water resistance, as well as anti-magnetism. The oversized buttons feature a checkered non-slip surface to make operations fast and safe. The millisecond stopwatch, speed indicator, world time, 5 sound reminders and much more give these models unparalleled functionality and performance.
