Brand description: G-SHOCK who 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, completed, the impact resistant 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 the G - SHOCK pursuing toughness and evolving, we will realize downsizing, and a new model of G - STEEL that extends the range of design variation will appear. The conventional layer guard structure · function is intact, realizing down sizing * to about 90% of the case as a whole. Due to the drastic miniaturization of the module, it made it possible to reduce the size of the case and make it thinner, and finished it into a middle size. Attention also to the finish of the detail, the index made of resin that can withstand impact realized face design that toughness and beauty are compatible with laser by scraping vapor deposition film applied on the surface with laser. GST-W 310D using stainless steel bezel and band, finished in a standard design that emphasized the hard feeling of metal. The GST-W 300 using a resin bezel has two types, a metal band and a soft urethane band. A thick soft urethane band that enhances wearability reduces the burden on the wrist even when worn for a long time. In addition, GST-W 300 of a casual design with a combination of GST-W 300 BD with fearless expression with black IP, resin bezel × stainless steel case, GST-W 300 for casual design, GST-W 300 G for gold and blue IP to produce coolness, It was. It has practicality such as multiband 6 corresponding to 6 standard stations in the world, needle retraction function to ensure visibility of liquid crystal part, full automatic double LED light excellent in time check in dark place. With the fusion of metal parts and plastic parts, G-STEEL which expanded the variation of toughness design, is the appearance of a model finished to middle size. (This is GST-W 300 G-1A 9 JF of the gold IP model.)
● Impact Structure

● 20 ATM water resistant function
● Radio reception function for 6 stations worldwide: Automatic reception (up to 6 times / day) (China radio is up to 5 times / day) / manual reception, compatible area / Japan · North America region · Europe region · China
* If you set the home time setting as a receivable city, you will receive stations that match the city. The time difference is set by the selected city.
● World Time: 48 time cities (31 time zone, with summer time setting function) + UTC (Coordinated Universal Time) time display, home time city replacement function
● Stopwatch (1/100 second, 60 minutes total, with split)
● Timer (set unit: 1 second, maximum set: 100 minutes, measured in 1 second increments)
● 5 time alarms (with countdown function) · time signal
● Battery indicator display
● Power saving function (In the dark, save time by turning off the display after a certain period of time elapses)
● Full auto calendar
● 12/24 hour display switching
● Operation sound ON / OFF switching function
● Double LED light: LED light for dial plate (full auto light, super illuminator, afterglow function, with after hours switching (1.5 seconds / 3 seconds)), LED backlight for LCD section (full auto light, super illuminator, Afterglow function, with afterglow time change (1.5 sec / 3 sec))
● Drive time in the state without solar power generation from the time of full charge: about 7 months in case of function use / case in power saving state / about 18 months
※ When radio waves are not received, 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.
Full specifications
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 withdraws 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 ambient light and darkness, only by darkening the arm more than a fixed angle only in the dark, the LED light is automatically lit. Two white LEDs are mounted, and the needle and liquid crystal are illuminated brightly. By combining with light storage, outstanding visibility is secured in the dark. Since it does not operate in a bright place, it is possible to suppress unnecessary power consumption.
Impact Structure
Hollow structure protecting module from external shock, cushioning protection of important parts in module, cushioning direct bezel shape to mitigate direct shock, omnidirectional guard structure, strong structure against drop impact.
20 ATM water resistant function
We adopt an airtight structure that corresponds not only to everyday life, but also unexpected bad weather, swimming, skin diving and other activities.
