Description

The Colmi R02 Smart Ring is designed for those who want the power of a fitness tracker without the bulk of a traditional smartwatch. Its exterior shell is made of durable, corrosion-resistant stainless steel, while the inner surface uses hypoallergenic epoxy resin to ensure comfort for sensitive skin. Weighing only 4.4 grams, it is virtually unnoticeable on the finger, making it the ideal device for continuous sleep tracking and daily activity monitoring.

Despite its tiny form factor, the R02 is equipped with the BlueX Micro RF03 chipset and advanced sensors that track 21 different sports modes. It captures essential health metrics, including real-time heart rate and blood oxygen saturation, and syncs this data via Bluetooth 5.0 to the QRing app. One of its most impressive features is its 5ATM & IP68 water resistance, meaning you can wear it while washing hands, showering, or even swimming in shallow water. The 17mAh battery provides up to 6 days of life on a single charge and is easily powered up via a dedicated magnetic charging cable.

Why Choose the Colmi R02?

• Stealthy Health Tracking: Unlike a glowing watch screen, the R02 tracks your vitals discreetly. It’s perfect for people who prefer traditional watches but still want smart health data.

• Superior Comfort: The 2.7mm thickness and ultra-lightweight build eliminate the "wrist fatigue" often associated with wearing smartwatches to bed for sleep tracking.

• Built for the Elements: With 5ATM water resistance, it is one of the few budget smart wearables you can truly wear 24/7, including during water-based activities.

• Premium Build: The CNC-polished stainless steel provides a jewelry-grade finish that looks like a high-end fashion accessory rather than a tech gadget.

• Cost-Effective Innovation: It offers the core functionality of premium smart rings (like Oura) at a fraction of the cost, making it the best entry-point into smart ring technology.
