Taking into consideration the latest Multi-Band 5 Atomic Solar Technology and the best balance of stainless steel and urethane, the new GIEZ from G-Shock is one tough and sophisticated timepiece. Utilizing a new 2-piece screw back construction on a full stainless steel case, allowed designers to capture full radio signal reception while maintaining G-Shock's legendary Shock Resistance and 200M Water Resistance. They've also created a more supple and breathable band through a high level molding technology that textures the bands underside.
