Introducing new color variations to the lineup of slim G-STEEL GST-B400 models with new, improved designs made possible by a thin module and carbon core guard structure. There is a standard model in this lineup, the GST-B400 with silver color face and resin band.
The GST-B400 is made possible by even further miniaturization of its parts and thinning of its modules without sacrificing any Bluetooth or solar function. Power consumption has also been significantly reduced.
In addition, the carbon core guard structure of this model helps to make it the thinnest of the G-STEEL Series (as of Apr 2021) while maintaining a high level of impact resistance. The thickness from the back cover to the bezel top is only 12.9 mm, which is more than one millimeter less than the GST-B100 model.
In terms of design, the number of button guards has been reduced as much as possible, enabling the use of large stainless steel buttons that are slim yet easy to operate.
The top bezel has been given five different finishes, while the middle bezel has been given four different finishes, which creates an elegant effect and changes the appearance of the texture of the metal depending on the viewing angle.

Introducing new Utility Color additions to GA-2100 thin, analog-digital combination line up from G-SHOCK, the watch brand that is constantly setting new standards for unmatched timekeeping toughness.
These new models combine practical and utilitarian colors of the bezels, faces, and bands that go well with street fashions, to create distinctive looks that fit right in with a wide range of fashions and activities. The new dual-layer molded bezel cover of the GA-2110SU model create great looking new designs.
These new G-SHOCK models combine thin cases with new designs.

Carbon Core Guard Structure
A new carbon core guard structure protects the module by enclosing it in a carbon case. The case is made of fine resin embedded with carbon fibers for outstanding strength, crack resistance, and durability.

From the MASTER OF G Series MUDMASTER, the watch that is designed and engineered to withstand rough land environments, come carbon resin models that incorporate a new type of structure.
The case is made of high-rigidity carbon material to protect against damage and deformation due to impact and other rough treatment, while metal button pipes ensure a tighter seal against the external environment. A filter further protects against the invasion of mud, for the high level of dust and mud resistance required when in severe environments. In addition, the dual back cover consists of a stainless steel panel back and an outer cover made of shock resistant fine resin embedded with glass fibers.
The bezel is formed of three layers of fine resin with carbon fiber inserts. The top layer is transparent, resulting in a bezel that shows the embedded carbon material.
Quad Sensor capabilities use compact sensors that make it possible to pack compass, altitude/barometer, and temperature measurements, along with an accelerometer that keeps track of your step count, into a compact configuration. This provides the outdoor adventurer with the means to keep track of the surrounding environment while on the go.
A special G-SHOCK app, which simplifies configuration of watch settings, also includes a new Mission Function. The app automatically records altitude data measured by the watch and route information acquired by a smartphone’s GPS. Manually obtained altitude points can be plotted on your route.
Altitude measurement and the step count are used to perform consumed calorie calculations that take up and down grades into consideration, and to record the results in an activity log.
A watch button operation can be used to record your current location with the app. Then the second hand indicates the bearing to the recorded location, while the digital display shows the distance to the location.
These new models also support Mode Switching Customization.
You can use the app to enable or disable modes individually so only enabled modes appear. You can even specify the sequence to be used when displaying the modes.
