At its launch in 1983, the G-SHOCK model DW-5000C with its revolutionary shock-resistant structure became the first wristwatch
to deny the conventional idea of the watch as a breakable item. In so doing, it established the “tough watch” as a new wristwatch genre.
G-SHOCK’s subsequent history of continuous evolution has now reached an impressive milestone with the 40th anniversary of its birth.
Structure. Functions. Materials. Design.
G-SHOCK focuses strict attention on these four factors in pursuit of further enhanced toughness.
Its primary objectives are robustness ensuring confident wear in any environment,
and practicality assuring reliable operation under any circumstances.
These objectives are realized in pursuit of the ultimate goal: supreme toughness.
Up to the present and into the future, with pride in its toughness,
G-SHOCK will continue to challenge even greater heights.
This is genuine toughness, passed down from one era to the next.
