★★★★★ Love my G-Shocks
Date posted : Thursday, Oct 31 2019

I love this watch. Love the blacked out look paired with the atomic/solar features. It’s a bit larger than my previous G-shocks but it is very comfortable on the wrist. Setting was easy and intuitive like my other G’s.

★★★★★ My favorite G-Shock yet
Date posted : Wednesday, Jul 10 2019

I have owned 5-6 G-shocks and this is my favorite. I love the solar atomic feature and the neon double LED light is great, that with the solar is why i bought it. Not many G-Shocks with that neon feature yet and this watch is sold only in Japan i think.

The watch is very gorgeous. I love the way it fits on the wrist. In addition it has a nice color with Beautiful neon light features. Easy to use after downloading the instructions in English from Casio. Love the tough solar and automatic time set feature. I will say that this is the best watch I ever owned.

Product Introduction A new model of radio wave solar with dust-proof and mud-proof structure will appear from the master of G series `` Mad Master ''
that is supposed to be used on the shore of extreme land where rubble and earth are piled up and scattered
In order to respond to use in harsh environments, the button guard cylinder structure that enables dustproof and mudproof performance is adopted for the button.
A cylindrical pipe that protects the button and a gasket built into the button prevent fine sand and mud from entering.
In addition, the cylindrical pipe plays a role in reducing the impact received by the buttons and enhancing operability, and is designed to withstand tough use.
Design expresses a rugged image of special vehicles and tools that are active in disaster relief
In addition, wide hour and minute hands and large Arabic numerals are used to improve visibility even under harsh conditions
The band is given a texture that is anti-slip, and the design is full of military taste everywhere.

Brand introduction G-SHOCK has built a new concept of toughness on watches.
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
