G-Shock

Active

Overview

G-Shock is a line of shock-resistant watches manufactured by Casio, designed for sports, military, and outdoor activities with features like chronograph, 200m water resistance, and alarms.² Launched in 1983, it established the 'tough watch' category through innovations in structure, materials, and functions, achieving over 200 models and 19 million units sold by 1998.¹²

History

G-Shock originated in 1981 when Casio engineer Kikuo Ibe led a team to develop a watch resistant to shocks, resulting in the DW-5000C launched in 1983 after two years of development.⁷¹ The model met 'Triple 10' criteria: 10m drop resistance, 10 bar water resistance, and 10-year battery life.⁷ Popularity grew in the 1990s with models like Frogman (1993, first ISO diver) and Mudman, expanding into 'Master of G' subfamilies; by 1998, over 200 models were released with 19 million units sold.²³
