This Casio men's MT-G series metal twisted G-Shock is tough and highly functional. The metal bezel on the front of the watch and metal back cover create a frame that holds inner workings to reduce the chance of impact force reaching the watch's module. Black finish metal and resin are combined to offer a distinctive and attractive look. This is one of the most durable and dependable radio controlled timepieces you can wear today.

Centrifugal Gravity-Resistant Structure - Highly detailed calculations based on the weight of each hand are conducted to achieve an optimal balance and assure stable hand movement, even under pressure from powerful gravitational forces.

Vibration-Resistant Structure - Alpha Gel is employed as an insulator surrounding the module inside the case. This structure prevents damage and operating errors under conditions of violent vibrations.

Smart Access - This proprietary CASIO system for analog movements combines multiple motors with an electronic crown structure for joint operation of various functions. Once unlocked, simple operation of the electronic crown makes actions such as World Time city selection and alarm setting even easier.

Core Guard Structure - The central portion "core" of the watch, which is resin, is sandwiched between upper and lower metal frames and secured with shared tension screws cushioned with Alpha GEL?. This new Core Guard Structure enabled MT-G to achieve its Triple G Resist toughness.

Layer Composite Band - The solid stainless steel band is layered on the underside with a soft-touch, low-thermal conductance resin panels for a luxurious feel against the skin and further enhances the MT-G's overall shock resistance.

High Quality 3D Index - The watch face's legibility has been enhanced by employing a three dimensional, layered dial structure featuring individually molded parts such as the time index and dial frame, ensuring clear visibility.
