Target: Men s
Set contents: Body, box, instruction manual, warranty card are included in the instruction manual

New model GA- that combines digital display with 3-needle analog from G-SHOCK, which continues to evolve in pursuit of toughness. 800 will appear

It is a new classic model with the G-SHOCK face icon front button located at 6 o'clock.

Adhering to the rugged design of the GA series, we adopted a compact case size and improved wearability by making it thinner.

The combination model allows the second hand to be driven independently, enhancing the legibility of sensational time, focusing on analog visibility in combination with a large three-dimensional index and hour and minute hands.

Lineup of Black and Red 2 models that symbolize the brand concept

1AJF has a second hand, 4AJF has a red to accent the hour hand, expressing toughness spirit.

In addition to the practicality of the combination model, it also has high usability such as the double LED light of the super illuminator and the needle retracting function.

The new standard design GA-800, which is simple but inherits the mainstream of G-SHOCK, is fused with a unique toughness design that is powerful in middle size.

It all started with a developer's passion for creating a watch that would not break even if dropped, and a reckless challenge that overturned the common sense of the time.

Over 200 prototypes have been repeated, and about two years have been spent, and the shock-resistant structure has been completed.

It is the birth of technology to play the core of toughness

Since then, G-SHOCK has continued to evolve endlessly

Structure, material, function

Pursuing further toughness in every aspect
