The MTG-B1000, which features a shock-resistant structure that fuses metal and resin, a smartphone link function, and radio wave solar power, is now available in a new model with a "volcanic thunder" theme. The new model features a bezel with rainbow IP, a multi-colored dial, and a skeleton red soft urethane band for the first time in the MT-G series to represent "volcanic lightning", which is lightning generated by volcanic eruptions. The rainbow IP is superimposed on the image of this phenomenon that occurs in a special environment, and is expressed in different shades for each item. The same IP is also applied to the packaging, making it a special model. New MT-G is a fusion of the hard feeling of metal and unique colors in a new design.
