The DW-001 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.
