Casio is pushing its ring watch concept further with the CRW-H001, a tiny wearable that now looks positioned as an alternative to devices like the Oura Ring. Instead of being just a novelty take on the brand’s classic watch style, the new model appears to add health and smart features that move it into the broader wearable market.
Based on the available details, the Casio CRW-H001 can track heart rate, blood oxygen, and sleep. Those features put it closer to health-focused smart rings than to traditional digital watches, even though Casio is still working within its own distinctive ring watch format.
The device also supports vibration alerts for incoming notifications, giving it another layer of everyday smartwatch functionality. That combination of wellness tracking and notification support suggests Casio is trying to blend compact design with practical connected features in a much smaller form factor.
Casio has experimented before with adding modern features to its familiar watch designs, but this release signals a different approach. By turning the follow-up to its viral ring watch into a more capable wearable, the company appears to be targeting shoppers who want smart ring-style tracking without giving up Casio’s recognizable design identity.
