G-SHOCK was born from a simple idea — a watch should not break when dropped. Back in 1983, the original square-shaped DW-5000C was created after Kikuo Ibe witnessed a child bouncing a rubber ball. It struck him that a watch floating within a rubber case would be impervious to shocks. After a bunch of testing and design with toughness in mind, the brand was born. Nearly 35 years and hundreds of models later, G-SHOCK is still best known for being some of the toughest, hard-wearing watches that money can buy.
