G-SHOCK Classic watch, black and neon blue, 51mm - GA-100-1A2ER

Introducing a collection of new G-SHOCK models, whose 35 mm diameter surfaces and large cases give a powerful and rugged appearance.

The popular G-SHOCK three-dial design incorporates an analog dial in the center, with digital dials on both sides. These watches are designed and engineered to offer exceptional shock and water resistance, as well as magnetic resistance. The oversized buttons feature a checkered non-slip surface to make operations quick and secure.
