The DW001 hit the scene in 1994, featuring the Capsule Tough design concept. Casio now introduces a new evolution of the watch driven by leading-edge technologies, featuring the Carbon Core Guard structure, a metal-clad exterior, and Smartphone Link functionality. On top of all this, the detachable urethane bezel provides a playful touch, offering the choice between two bezels — metal or urethane. A reimagined form of Capsule Tough has arrived, maintaining the design of the original while taking on a fresh new character all its own. A translucent bezel and band are included, offering 12 different customizable design combinations. The additional bezel features two-tone molding in yellow and green, and the additional band displays blue gradations. A slide lever makes the parts easily interchangeable.
