Episode Overview

In this episode of The Design Vault, hosts Albert Shum and Thamer Abanami explore the remarkable story of the Casio G-Shock DW5000C—a watch born from heartbreak that revolutionized an entire industry. When engineer Kikuo Ibe's cherished graduation gift from his father shattered on the floor in 1981, it sparked a two-year obsession to create the "unbreakable watch." What emerged wasn't just a timepiece, but an entirely new design language of durability that would influence everything from smartphones to extreme sports culture. This episode reveals how three engineers, armed with the "Triple 10" challenge and radical thinking, transformed failure into one of the most iconic products of the 1980s.
