Casio Men's G-SHOCK Mt-g B4000 MTG-B4000B-1A2JF Watch

Product Highlights
The MT-G series pursues innovative structural beauty by combining the origin of G-SHOCK, resin, and metal materials. The MTG-B4000 features a new dual-core guard structure developed with AI utilizing accumulated impact resistance data, along with a fusion frame of carbon and stainless steel. This combination has brought forth an innovative design that embodies both strength and beauty. Through the collaboration of AI and human creativity, materials, structure, and form are organically integrated to achieve a unique functional beauty. The development process leveraging AI optimizes the analysis and simulation of designer base concepts, iteratively complementing each other to realize shapes that balance functionality and beauty. The carbon layered frame is intricately shaped by carving out a stacked material of carbon and glass fiber in a three-dimensional form, creating a complex frame. The stainless steel parts of the bezel adopt a dual bezel design for both the inner and outer sides. Each part is meticulously polished with hairline and mirror finishes, resulting in a beautifully crafted timepiece. The MTG-B4000B-1A2 features a newly developed blue-gray IP treatment on stainless steel parts like the bezel. Additionally, it incorporates high-transparency sapphire glass and meticulous dial design crafted with Casio's Yamagata factory's fine processing techniques, paying attention to every detail. On the functional side, it offers Bluetooth® connectivity to the exclusive "CASIO WATCHES" app for time information retrieval. It also includes features like Multi-Band 6, Tough Solar, and a high-brightness LED light, providing practical functionalities.
