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. 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. A special G-SHOCK app, which simplifies configuration of watch settings, also includes a new Mission Function.

Mud-resistant structure 

(dust and mud resistance)

By using hard materials in the case, the design of the watch prevents damage and deformation from shocks and other sources, and achieves a high level of airtightness without the use of metal parts. In addition, the watch contains a filter that avoids the intrusion of dirt, allowing it to exhibit strong mud resistance in harsh environments.

Carbon core guard structure

A new shock-resistant carbon core guard structure integrates the case. An external structure capitalises on its toughness and lightness.

Shock-resistant button

The new carbon case helps to develop a new structure of button. This also enables removing the button guards from the exterior.

Exterior using a dual-layered case back

GG-B100 features a stainless-steel panel back that keeps the watch airtight, as well as a fine resin glass fibre case back that makes it tough against shocks. This design is inspired from the petrol tanks carried on offroad vehicles often used on rough roads.

Shipping Restrictions by location.

It's up to YOU to know the laws in your state, county and city and to fully comply with them. The following are examples of some state and local restrictions governing various products. This list shows products that are prohibited in the locations indicated. When criteria must be met for ownership, those are also listed.

Unable to ship due to shipping restrictions.

In some situations we are unable to ship an item because our shipping partners require us to restrict it to ground transportation only (the FAA will not allow them to transport it on an airplane).

If you have a restricted item on your order, we can only provide ground shipping options. Sometimes you live in a place that does not have guaranteed ground delivery, and in this instance we are not able to ship the restricted items to you.

You can remove the restricted items if you would like to receive the items on your order that are allowed to be sent via non-ground delivery.
