At a time when watches were seen as fragile, delicate instruments, Casio’s head of watch design, Kikuo Ibe, set out in 1981 to create “a watch that doesn’t break, even when dropped.” After 200 prototypes and two years of development, the Casio G-Shock was launched in 1983. Gaining its now legendary toughness from Ibe’s revolutionary decision to suspend the module inside a hollow rubber structure, the G-Shock has been the go-to name in superbly durable and precise wristwear ever since.
