Casio G-Shock GGB100XMB-1A MUDMASTER MASTER OF G SERIES Quad Sensor Black Watch

At A Glance

For the fearless adventurer, a tough and rugged Master of G MUDMASTER featuring a strong, durable metal bezel.

The watches of the G-SHOCK Master of G line, developed for professionals working in the harshest environments, come equipped with even tougher functionality. And the MUDMASTER takes this another step further with the ability to handle the roughest rubble and debris-strewn terrains, earning the appreciation and trust of rangers and rescue teams operating in extreme environments.

The GG-B100XM-1A features a silvery stainless-steel bezel with a honing finish, delivering outstanding scratch resistance that protects against mud and dust and a subtle matte texture that minimizes reflected light. The stainless-steel GG-B100XMB-1ADR bezel is ion-plated in black with a mirror finish for both outstanding scratch resistance and a refined luster.

These MUDMASTER employ high rigidity carbon for the carbon fiber-reinforced case to keep damage and warping at bay and ensure a tight seal and excellent shock resistance. Featuring a filter to protect against mud, a stainless-steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibers, these timepieces provide a high level of resistance to dust and mud. Key components for the case and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.

Practical and functional, the watches are equipped with digital compass, altimeter/barometer, and thermometer, as well as step counter. Easily correct the time using the dedicated app and tap into loads of other useful features including the Mission Log, which automatically records altitude data obtained from the watch and route data obtained by your smartphone.

You can depend on these tough timepieces to deliver what you need to make quick decisions and take decisive action.
