Casio G-Shock Watch Ring CRW-001G-9ER

A watch… for your finger. A surprising idea that combines practicality, compact design, and a touch of pure fun. This digital ring watch reinterprets the iconic Casio style in a miniaturized and fully functional version.

Creating a ring with the shape and functions of a real digital watch was no easy feat: sophisticated MIM (Metal Injection Molding) technology was used to faithfully reproduce every detail in stainless steel. The structure is then finished with gold ion plating for a dazzling, sophisticated look.

The unibody case, combined with a special glass bonding technique, ensures perfect sealing for daily water resistance while still maintaining the battery replaceability. The module of a classic digital watch has been reduced tenfold and combined with a micro-button battery, creating a true, fully functional three-button digital watch... but in a ring format.
