Casio Men's G-SHOCK MT-G B4000 MTG-B4000-1AJF Watch

Product Highlights
Introducing the MT-G series, a fusion of the resin and metal materials that are the origin of G-SHOCK, striving for innovative structural beauty. The MTG-B4000 features a new Dual Core Guard structure developed with AI utilizing accumulated impact resistance data, along with a frame that combines carbon and stainless steel. This combination has brought to life an innovative design that embodies both strength and beauty. Through the collaboration of AI and human creativity, materials, structure, and form are organically integrated, pursuing a unique functional beauty. The development process utilizing AI optimizes the analysis and simulation of designer base concepts, achieving shapes that balance functionality and beauty through complementary iterations. 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 on the inside and outside, meticulously polished with hairline and mirror finishes for a beautiful appearance. The MTG-B4000B-1A2 features newly developed blue-gray IP processing on stainless steel parts like the bezel. Additionally, it incorporates highly transparent sapphire glass and meticulous dial designs crafted with Casio's Yamagata factory's fine processing techniques, paying attention to every detail. On the functional side, it connects to the exclusive app "CASIO WATCHES" via Bluetooth® communication for time information retrieval. Equipped with Multi-Band 6, Tough Solar, and a high-brightness LED light, it offers practical functions.
