MT-G This watch is a new addition to the MT-G lineup that combines metal and resin into attractive, high-function timepieces. This new model features a new Core Guard Structure that provides outstanding shock resistance. The metal bezel on the front of the watch and metal back cover create a frame that houses the inner workings to reduce the chance of impact force reaching the watch's module. In addition, αGEL®* is used at points of contact on the bezel and back cover to further absorb impact. All of this is in addition to G-SHOCK's renowned Triple G Resist structure. The case and band surfaces are done to a hairline finish, while the beveled surfaces of parts are sallaz polished to a shiny finish. The large resin dial ring combines CASIO original cutting technology and new evaporation technology, which enable both light weight and outstanding shock resistant. The band of the watch is fitted with highly durable fine resin panels that deliver a great fit to the wrist along with light weight. * αGEL® is a material with silicone as its main component and featuring superior vibration-absorption capabilities. * αGEL® is a registered trademark of Taica Corporation in Japan, the United States and other countries.
Core Guard Structure Four stainless-steel pipes form a metal frame that joins the bezel securely with the case back. A resin case is mounted inside the frame to protect the module from direct shocks. This CoreGuard Structure with its metal frame mirrors the basic G-SHOCK concept of a “hollow structure” in which the module is fl oated in the air with support at just a few points.
Layered composite band Metal band parts are combined with lightweight but highly durable fine resin parts to achieve a solid feel and reduce weight simultaneously.
Four-layer dial structure The 3D dial, comprising four layers and conveying an impression of depth, is mounted with oversized hour markers with prominently protruding edges. Despite the use of resin material to absorb shocks, G-SHOCK's unique cutting and evaporation technologies have helped to produce a robust, radiantly beautiful form.
Sallaz polishing The bezel, bevelled case sections are processed with Sallaz polishing, a superlative metal-polishing technique, to create beautiful mirror surfaces.
