Casio to Release Shock Resistant MT-G with Slimmer Profile
Featuring a Newly Developed Slim Module and Shock-Resistant Structure



Norderstedt, March 15, 2022 — Casio Europe GmbH announced today the latest addition to the G-SHOCK brand of shock-resistant watches. The MTG-B3000, which boasts an innovative slim module and shock-resistant construction, is an even more streamlined addition to the MT-G line of timepieces, all of which feature a construction that makes 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 case that is more than 2mm slimmer than the previous model.*

Making full use of high-density mounting technology, Casio has developed the slimmest module yet for a G-SHOCK solar chronograph. To address the all-new shock-resistant structure required by this new slim module, Casio delivers 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.


Repeated processes of pressing, cutting, and polishing are applied to craft a stainless steel case back that protrudes upward in a 3D form. The raised sides protect the crown and buttons and serve as the lugs to secure the band. All of these innovative designs and technologies result in a metal timepiece with a mere 12.1mm case that is extremely comfortable to wear. 


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