Overview
Oura Ring 4 Ceramic pairs a high-performance zirconia ceramic exterior with a seamless titanium interior. Each ring is fired to strengthen the ceramic and give it a smooth, polished finish. It is 7.9 mm wide and 3.51 mm thick, weighs 5.1 to 8.1 g depending on size, is water resistant to 100 m and lasts 5 to 8 days on a charge. It has the same Smart Sensing and health tracking as Oura Ring 4: sleep, readiness, activity, heart rate, HRV, blood oxygen, temperature trends and stress.
