Casio entered watchmaking in 1974 and changed the category permanently in 1983 with the launch of the G-Shock, a watch engineered to survive drops, shocks and water exposure that conventional watches were never designed to withstand. The original development brief reportedly called for a watch that could survive being dropped from a third-floor window, a target that shaped a design philosophy still visible in every G-Shock produced today. Decades later, the G-Shock and the digital Casio catalogue more broadly have built a collector culture entirely separate from traditional luxury watchmaking, with certain vintage and limited-edition references commanding prices well beyond their original retail cost.
