Carbon Core Guard structure
From G-SHOCK, the watch brand that is constantly setting new standards for unmatched timekeeping toughness, comes a new series of GA-2000 timepieces that are destined to become the next-generation standard of the G-SHOCK world.
The three models of the GA-2000 lineup were designed with a utilitarian flair.
A multidimensional face, a big front button, and other design elements create a powerful and tough design.
