GSHOCK has built a new concept of toughness in brand introduction watches
It all started with a passionate belief in creating watches that would not break if dropped, a reckless challenge that overturned common sense at the time.
More than 200 prototypes were repeated, and it took about two years to complete, and the impact-resistant structure was completed
The birth of tough technology
Since then, GSHOCK has continued to evolve
Structure, material, function
Pursue more toughness in every aspect
