Toughness Defined
Casio entered watchmaking in 1974 and changed the game with the G-Shock in 1983 — a watch engineered to survive a 10-meter drop, 10-bar water resistance, and 10-year battery life (the 'Triple 10' standard). Engineer Kikuo Ibe spent three years dropping prototypes from the third floor of a building until the shock-resistant module worked. The G-Shock became a cultural icon across military, hip-hop, extreme sports, and streetwear communities. The metal-cased GM and MRG lines elevate the concept to luxury territory. With over 100 million G-Shocks sold, Casio proved that durability and accessibility aren't compromises — they're features.
G-Shock Triple 10 concept (1983): 10m drop, 10 bar WR, 10-year battery. Over 100 million G-Shocks sold worldwide. MR-G line pushes into luxury territory.
Limited G-Shock collaborations (BAPE, Kith, John Mayer) trade above retail immediately. Vintage Casiotrons and early G-Shocks are emerging collector categories.
