Oura Horizon Smart Ring

Each style has identical technical and hardware capabilities.

• Water resistant up to 100 m (more than 328 ft.)
• Lighter than a conventional ring (4 to 6 grams)
• Titanium: durable and wearable
• Includes size-specific charger and USB-C cable
• With daily wear, the ring may develop scratches

Ring sensors should be on the palm side of your finger for the most accurate reading. To help ensure optimal positioning, Oura Horizon has a sleek, uninterrupted circular design with a pill-shaped dimple on the bottom, and Oura Heritage has a classic, plateau design with a flat surface on top.
