Casio Ships First Smart Ring With On-Device LCD and Full Health Sensors

Casio's CRW-H001M-8, launching first in China at roughly $294, is the only smart ring pairing a functioning LCD display with a full health sensor stack — heart rate, blood oxygen, sleep, body temperature, steps, and calories. Every competitor, including Oura, remains screenless. Four-to-six-day battery life suggests the display draws meaningful power. Casio has not yet detailed the companion software layer.
