Product details

Oura Ring 4 Ceramic is the modern realisation of a revolutionary smart ring technology that combines refined elegance with everyday comfort. The high-performance ceramic exterior is designed to keep up with you in all your activities. The Ceramic collection is available in four unique colours: Midnight, Petal, Tide and Cloud. Each new colour has been designed to accentuate your style and personality.

This colourful new edition features the same cutting-edge technology as Oura Ring 4, tracking over 40 biometrics on your health and providing personalised insights on your sleep, activity and daily form, stress, heart, metabolic and women's health, among others. The ring was developed around the advanced Smart Sensing measurement technology, which enables the most accurate and uninterrupted measurements as it adapts individually to your finger. With 5-8 days of battery life, you get a complete picture of your health. It has recessed sensors on the inside, making it comfortable to wear and pleasant to the touch - even on sensitive skin. Oura Ring 4 Ceramic is available in sizes 4-15 and four stunning designs to effortlessly fit your style and your finger.
