Casio has taken a bold step into the realm of smart wearables with the CRW-H001, its first smart ring that integrates health and activity tracking with digital connectivity. This metallic marvel is exclusively available in China, reflecting Casio’s evolution from traditional timepiece maker to innovator in personal technology.

Miniaturized technology in a sleek, full-metal design

The CRW-H001 compresses the functionality of a smartwatch into a ring-sized accessory, necessitating innovative construction techniques. Casio employs metal injection molding (MIM) to craft a one-piece body that maintains the aesthetic of their classic digital watches. The result is a durable ring with a mirror-like finish, engraved with metallic-shine lettering. Advanced sensors and a digital display are seamlessly integrated into this tiny form.

The ring pairs with smartphones to deliver discreet alerts via a low-power vibration motor. Incoming calls, messages, alarms, and health notifications are signaled through gentle vibrations, replacing the traditional wristwatch glance with subtle finger feedback.

Transforming from watchmaker to smart wearable leader

Casio’s CRW-H001 redefines its ring watch series by prioritizing health tracking. While earlier models offered miniaturized replicas of iconic digital watches, the new smart ring enters the competitive landscape of health-focused wearables. It connects seamlessly with Casio’s companion smartphone app on iOS, Android, and selected HarmonyOS devices, though some features may not work with newer HarmonyOS versions.

Available in three sizes—9, 10, and 11—the CRW-H001 offers versatility to suit different users. It is packaged thoughtfully with a dedicated storage box and carrying pouch, making it a practical choice for daily wear.
