Casio is launching a ring-shaped digital watch that also functions as a health-tracking smart ring, creating an unusual alternative to conventional wearables such as the Oura Ring. The device matters because it combines Casio’s distinctive miniature-watch design with features normally found in discreet fitness rings, potentially appealing to buyers who want more visual character.

The CRW-H001M-8 is due to launch in China first at about $294 including local taxes. It tracks heart rate, blood oxygen, sleep, body temperature, steps and estimated calories burned, while retaining a clock, stopwatch and calendar; Casio says its battery should last around four to six days.
