- Casio introduces the CRW-H001, its first-ever smart ring with built-in health tracking.
- The device utilizes metal injection molding (MIM) to preserve classic digital watch aesthetics.
- A low-power vibration motor delivers discreet smartphone notifications straight to the finger.
- The smart ring is rolling out exclusively in the Chinese market.
After previously downsizing its digital watches into finger-sized fashion accessories, Casio is taking the concept a step further by introducing its first dedicated smart ring. The CRW-H001 builds directly upon the brand's earlier series of functional ring timepieces, transforming them into a comprehensive wearable device equipped with health monitoring, activity tracking, and smartphone notifications within a unibody metal chassis. Launching exclusively in China, this new release highlights a clear shift from novelty timepiece to a connected personal health gadget, capturing the ongoing convergence of traditional watches, jewelry, and wearable wellness tech.
Unlike previous iterations that faithfully replicated the exact functions of miniature digital watches, the CRW-H001 introduces advanced biometric sensing alongside standard digital timekeeping. The ring tracks daily step counts, calorie expenditure, and physical workouts such as walking, running, and cycling. Furthermore, it keeps tabs on heart rate, blood oxygen saturation levels, body temperature, sleep patterns, and workout recovery metrics.

Engineering a smart ring requires extreme miniaturization, forcing manufacturers to pack complex sensors, a micro-battery, and a haptic motor into an exceptionally tight space while maintaining structural integrity. By employing metal injection molding (MIM), Casio is able to replicate intricate watchcase geometries at a microscopic scale, proving that traditional watchmaking design languages can successfully transition into ultra-compact smart jewelry.
Compressing advanced smartwatch capabilities into a ring-sized form factor demanded a complete overhaul of Casio's manufacturing and construction methods. The company utilized metal injection molding (MIM) to recreate the intricate geometry of its classic watch cases at a much smaller scale, producing a seamless one-piece metal body that preserves the visual DNA of its digital watches. A vapor-deposited mirror finish adds a metallic sheen to the engraved lettering, while miniature internal electronics seamlessly combine a digital display with integrated sensors right on the inner surface.
The CRW-H001 also operates as an extension of a paired smartphone. Utilizing a low-power internal vibration motor, the ring delivers discreet haptic alerts for incoming phone calls, messages, alarms, and selected health notifications, replacing the traditional glance at a wristwatch with a subtle vibration right on the wearer's finger.
