Casio announced Slimmer Profile Shock Resistant MT-G

Casio announced Slimmer Profile Shock Resistant MT-G, the latest addition MTG-B3000 featuring an innovative slim module and shock-resistant construction. These latest additions are even more streamlined models than before to the MT-G line that features a construction making the most of the properties of both metal and resin.

The MTG-B3000 pairs an innovative slim module and shock-resistant structure to achieve a streamlined shock-resistant watch with a case that is more than 2mm slimmer than the previous MTG-B1000 model.

By making full use of high-density mounting technology, Casio has developed the slimmest module for a G-SHOCK solar chronograph. To address the all-new shock-resistant structure required by this new thin module, CASIO delivered an even more advanced Dual Core Guard structure. The newly developed guard structure protects the module with a carbon-reinforced resin case and encloses the exterior with metal components, retaining the metal look and texture while reducing the weight, and further protecting the module with a case back featuring raised sides.

To craft a stainless-steel case back in 3D form, pressing, cutting, and polishing processes are applied repeatedly. The raised sides protect the crown and buttons and serve as the lugs to secure the band. These innovative designs and technologies result in a metal timepiece with a mere 12.1mm case that is very comfortable.

The MTG-B3000 features radio-controlled calibration and Smartphone Link connectivity via Bluetooth. This watch connects with the dedicated CASIO WATCHES smartphone app to automatically adjust to the correct time. They also comes equipped with a solar charging system and high-brightness LED light for practicality and convenience.
