Ultrahuman Ring Air Size 12 Brushed Rose Gold

The Ring Air Size 12 Brushed Rose Gold tracks heart rate, sleep, steps, and skin temperature for continuous health monitoring.

This fitness tracker suits users who want discreet, all-day and overnight tracking without the bulk of a smartwatch. Its size 12 fit is designed for comfort and accuracy, making it suitable for those who prefer a ring form factor for activity and sleep insights.

The ring connects to iPhones running iOS 15 or later and Android devices running Android 6 or later via Bluetooth v5.0. Its battery lasts 4 to 6 days on a full charge, supporting extended use between charges. Water resistance up to 100 meters for up to 12 hours allows for wear during swimming or showering. The outer shell is made from fighter jet grade titanium reinforced with tungsten carbide carbon coating, while the inner surface uses medical-grade hypoallergenic epoxy resin for skin comfort.

Model 170797 in brown comes with a 1 year manufacturer's warranty.
