Casio Unveils $294 CRW-H001M-8 Ring Watch With Health Sensors

Summary

  • Casio’s new CRW-H001M-8 adds continuous heart-rate, blood-oxygen, body-temperature and sleep tracking to its ring watch line, turning the 2024 CRW-001 from a display novelty into a health wearable.
  • At 19 grams, the ring is far heavier than most smart rings, and that matters most for sleep tracking because users must keep it on overnight for the feature to work.
  • Three sizes—9, 10 and 11—replace the original one-size design with plastic spacers, a change that also helps the optical sensors maintain direct skin contact.
  • Priced at 1,990 yuan, or about $294, the silver-only model launches first in mainland China with Bluetooth syncing to the AIZO Ring app, 4-6 days of battery life and China-only after-sales support.
  • The release pushes Casio deeper into a niche it has expanded over 19 months, while undercutting Oura on upfront price even as software quality remains an open question.
