Casio Computer Co, Ltd, based in Shibuya, Tokyo, Japan, has announced the latest addition to its family of G-Shock watches. The new Mudmaster GWG-B1000, a member of Casio’s ‘Master of G’ lineup, features a complex stainless steel front button guard manufactured by Metal Injection Moulding (MIM).
With its main case made from carbon fibre-reinforced resin, the Mudmaster GWG-B1000 is designed to withstand harsh environments and employs a newly developed guard structure that features components made with stainless steel.

In addition to the MIM front button guard, the other stainless steel guard components include the upper and lower bezel guards. These are machined out of pre-forms that are first forged into bezel shapes, explained Casio. Carbon fibre-reinforced resin is then used for left and right side button guards.
MIM enables the production of high-precision metal parts with complex three-dimensional shapes, and was said to be the ideal production method for the front button guard. “We use Metal Injection Moulding to achieve a dimensional form befitting the Master of G name,” stated Kazuyasu Kojima from the Product Planning Section, Timepiece Business Unit at Casio.
