Casio developed its Tough Solar technology to reduce waste and be friendly to the environment. This G-Shock Digital GR-8900A-7ER makes full use of this technology, integrating micro solar panels on the face to recharge its batteries on its own. Also this version goes back to basics by using minimal colors, staying well away from bright colors. Matte grey wrist bands and casing gives a classic look, along with the black face and reversed LED complementing the timepiece. The chunky casing offers shock resistance and magnet resistance and a full range of digital functions make this a timeless watch for active individuals.
