Brand Description: G-SHOCK built a new concept called toughness on the clock. Everything began with a reckless challenge that overturned the common sense at the time, a developer’s faith belief that it would make a timepiece that would not break even if dropped. Over 200 prototypes were repeated, about two years have been spent, and the completed shock structure. It is the birth of technology that is the core of tough. Since then, G – SHOCK has continued evolution without end. Structure, material, function. Pursue further toughness from every aspect.

From G – SHOCK pursuing toughness and evolving, G – STEEL will open up a new frontier of metal design by fusing different materials. Lineup of a new color of GST-W 300 combination that fulfilled downsizing due to miniaturization of modules. I imagined a deeply snowy white, a bezel of white, finished in a model that colors the midwinter with treated bands. An index of three-dimensional modeling with edge effect by original microfabrication technology, a lightweight by aluminum material and an analog needle resistant to shock, gorgeous gold coloring. I expressed the glowing light which is seen in illumination etc. in gold. Combined with pairable G-MS, it is finished in a design that can be enjoyed as a pair model. In addition, it realizes downsizing, it has become a compact case hard to interfere with cuffs. It is G – STEEL which is active in casual fashion in midwinter.

* When radio wave reception is not performed, it operates with normal quartz accuracy (average monthly difference of ± 15 seconds).

Layer guard structure

By using different materials for the bezel part, we realized a new shock-resistant structure by adopting a two layer structure.

Multiband 6

Received the standard radio waves of 6 stations in the world. Automatic time adjustment in Japan, North America, Europe, China is realized.

Tough Solar

Unique solar system that turns even light into power. Adopting a film-like solar cell that is hard to crack, precisely calculate the area of ​​liquid crystal and printing. By connecting six cells in series, it is designed so that the received light amount of each cell is the same.

Needle retraction function

A function that temporarily retracts the hour and minute hand overlapping on the liquid crystal display from the current position with one push to make the display data easy to read.

Full Auto Double LED Light

By sensing the brightness of the surroundings and turning on the arm more than a certain angle only in the dark, the LED light is automatically lit. Two white LEDs are mounted, and the needle and the liquid crystal are illuminated brightly. By combining with light storage, excellent visibility is secured in the dark. Since it does not work in bright places, it is possible to suppress unnecessary power consumption.

In case

Impact Structure

Hollow structure protecting module from external shock, cushioning of important parts in module, cushioning direct protection by unique case · bezel shape, omni-directional guard structure to mitigate impact, has a structure resistant to drop impact.

20 ATM water resistant function

We adopt airtight structure corresponding to activities such as daily life, as well as unexpected bad weather, swimming and skin diving.
