This Casio G-Shock Master of G Mudmaster model is a collaboration with the world-famous snowboarding brand BURTON in 2020.

It is designed for use in extreme natural snowy environments and with standard features like shock resistant, dust resistant, and mud resistant MUDMASTER as based on the GG-B100 series, which uses carbon materials to create a new tough and rugged structure.

The pattern used on the strap is directly reflecting the nature and feel of the brand and the sports it is associated with.
