In late July 2026, Casio introduced the CRW‑H001M‑8 smart ring in China, a retro‑styled wearable that adds continuous heart‑rate, SpO₂, temperature, sleep and menstrual‑cycle monitoring, along with step counting and vibration alerts. The device, priced at about 1,990 yuan, is sold only in China and connects to the AIZO Ring app.

A week later, coverage expanded to include Hama GmbH & Co KG’s Ring One, a stainless‑steel smart ring offering similar health metrics, 120 sport modes, water resistance to 5 ATM and up to 20 days of extra charging. Priced at €129 for US sizes, the Ring One syncs with a free Hama Active app and carries no subscription fees. The report also reiterated Casio’s CRW‑H001M‑8 details, underscoring a growing competitive field of health‑tracking smart rings entering the market.
