Charging case for easy storage and charging
The compact charging case works as a practical docking station and a protective travel case. Simply place the ring into the cradle and charging starts automatically, increasing day-to-day convenience.
Elegant black design with integrated sensors
The glossy black ring looks like jewelry, yet it hides the electronics and sensor module inside for monitoring. It is ideal for discreet all-day wear at work and during sports.
Lightweight construction for comfortable wear day and night
Low weight and a slim profile support comfort during long-term wear. Thanks to this, you can collect activity and sleep data without limitations while working, writing, or exercising.
COLMI R02 is a smart ring in size 10 (inner diameter 19.8 mm) that combines an elegant look with practical functions for everyday monitoring. Thanks to its low weight and thin profile, it is comfortable to wear all day and night – ideal if you don’t want to sleep with a watch but still want insight into recovery.
In the background, it continuously tracks key indicators and stores them in memory, so you won’t lose data even when your phone isn’t with you. After pairing with the QRing app, you get clear statistics and long-term trends.
