Built for the pilot that encounters severe environments, Casio G-Shock's Carbon Core Gravitymaster Limited Edition Watch is designed to withstand rigorous levels of adventure
The 50mm case and back cover are expertly crafted from fine resin mixed with carbon fiber, an innovative composition that is lighter and more durable than resin
This allows the internal mechanics of the watch to be protected from shock-induced damage and deformation
